performance degradation over time

Post by jesse » Thu Apr 04, 2013 11:41 am

hi zevo users,

i have a hackintosh (i know, sorry) with one boot disk and a zpool raidz1 named Users, consisting of a pair of 250gb disks. i recently added a 750gb disk and used it to make a single-disk zpool named Users2, and used rsync to copy all of my data from the old pool to the new one.

when i created the Users zpool (not sure of exact date, but months ago) it was pretty snappy. from memory i would get 30MB/s during scrub operations. not blistering speeds, but more than serviceable. right now, doing simultaneous scrubs on Users and Users2, there is a marked performance difference between the pools:

crackmonkey:~ % zpool status -v | egrep 'scrub|scanned'
scan: scrub in progress since Thu Apr 4 10:20:52 2013
2.50Gi scanned out of 168Gi at 11.9Mi/s, 3h57m to go
scan: scrub in progress since Thu Apr 4 10:20:55 2013
7.18Gi scanned out of 168Gi at 34.7Mi/s, 1h19m to go

the first pool is Users, running slowly, and the second is Users2, running much more quickly. i started both scrubs within seconds of each other, Users first. if i stop the scrub of Users2, the scrub of Users speeds up a little bit, but not a lot:

crackmonkey:~ % zpool status -v | egrep 'scrub|scanned'
scan: scrub in progress since Thu Apr 4 10:20:52 2013
7.45Gi scanned out of 168Gi at 15.3Mi/s, 2h58m to go
scan: scrub canceled on Thu Apr 4 10:28:01 2013

i have read threads of people seeing performance degradation corresponding to increased uptime, but this is right after a reboot, and i'm only logged in remotely to minimize processes owned by me. here are my processes:

crackmonkey:~ % ps -ef | grep 501 | grep -v grep
501 199 1 0 4:19PM ?? 0:00.14 /sbin/launchd

and here's lsof output showing what processes have files open in Users and/or Users2:

a long time ago (ten's complement) i complained about performance, and accidentally discovered that recreating my zpool had a similar speed boost. i followed the same procedure (two disks in mirror, add extra disk, make new pool,
rsync data from old pool to new pool, remove old pool, attach second new disk to new pool) and things were much more snappy, even though the data should be identical. i feel like i'm seeing the same behavior now. same zpool version, same zfs version, same data on the pools, and the new pool exhibits performance characteristics nearly identical to what the old pool showed when it was brand new.

has anyone else noticed a drop in performance that disappears when the zpool is recreated?

thanks,

jesse

sorry, this is 10.8.3, zevo 1.1.1, only third party kexts are a NIC driver, fakeSMC and zevo. system is stable if a bit of a dog. my secondary account that does not have a zfs home directory is pretty snappy.

It would be very helpful to have the output of zpool status -v and zpool iostat -v for at least these two pools. A snapshot of zstat would be useful as well.

For a pair of identical disks, a mirror will behave better than a raidz1 for a variety of reasons, most notably that parity does not need to be calculated or stored and reads can come from any mirror component. A mirror is also more flexible, since one can attach and detach physical devices to the vdev to change the replication level. This is one bit of legacy where zfs exposes too much tunability; there is pretty much never any reason why anyone should want to create a two-physical-disk raidz1 vdev, and attempting to do so really ought to raise a warning when the '-f' flag is not provided to zpool create.

Time estimating algorithms are messy things; the important numbers there are the running average Mi/s figures. It is not terribly surprising that for very similar data[*] the raidz1 vdev will take longer. Scrubs proceed to examine blocks in birth order, as do resilvers; this ensures that the newest metadata is dealt with first, then the most recently created data blocks, then less recent data, and so forth. This has several operational advantages, and one big performance disadvantage in the form of avoidable disk IOPS. Scrubbing works at the pool level, and block checking is spread out to the storage vdevs based on their workload. Scrubs are low prirority, so that the pool remains usable while they're in progress.

The devices in mirror vdevs are examined concurrently; the birth orders may also vary slightly for a number of reasons (previous disconnections and subsequent resilverings, differences in performance absorbed by the write scheduling system in zfs, and so forth). One drive only has to wait on another drive in a mirror vdev when a repair is necessary. The devices in raidz1 (and raidz2 and raidz3) cannot be examined fully independently because each vdev block is likely to be scattered across several disks and the parity block also needs to be read and verified. However there is often still concurrency available in wider raidzN vdevs because of the dynamic stripe width, although it will never be as high as in a mirrored vdev.

750gb disk and used it to make a single-disk zpool named Users2,


A single device vdev is a degenerate case of a mirror. They are also DANGEROUS since they offer little protection for your data. A burst of errors will make the whole pool unavailable. A variety of errors may also lead to actual data loss up to and including rendering the whole pool unimportable, no matter how many vdevs are in the pool.

simultaneous scrubs on Users and Users2


Generically, if you stop the scrub on Users2, does the scrub on Users speed up ? (Also, what about vice-versa?)

Specifically, the answer to this would depend on things like the actual hardware involved and how it's connected to your machine, and
whether there is any other activity on the pools other than the scrub. Scrubs are *usually* IOPS-limited rather than bandwidth-limited.

Generically again, scrubbing takes a long time. Do you know why you are scrubbing in the first place?

Also, returning to the [*] above, while the datasets in the pools have identical information in them from the perspective of the zfs posix layer (ZPL), which is what tools like rsync or rmdir care about, they may not be the same at lower layers, and they may diverge remarkably at the level of vdevs and physical disks.

Vdevs, for example, are assigned about 200 metaslabs, which are allocation areas. Differently-sized vdevs will thus have differently-sized metaslabs. As files are added in the same order, even if allocation were always first-fit, the layout would diverge. Additionally, not all allocations are first-fit, for a number of reasons. Ditto blocks (all zfs metadata, and any user data where the copies property is greater than 1) will be spread to different metaslabs. In a two-disk raidz, that means verifying each block of metadata means both disks have to do long seeks at nearly the same time; your one drive vdev has to do a similar seek but does not have to wait on the other disk.

Finally, your figures are all quite early in the scrubs -- the first few GiBytes.

640Mi scanned out of 168Gi at 10.3Mi/s, 4h36m to go
919Mi scanned out of 168Gi at 7.53Mi/s, 6h18m to go
1.67Gi scanned out of 168Gi at 9.39Mi/s, 5h2m to go
2.43Gi scanned out of 168Gi at 10.3Mi/s, 4h34m to go

and
2.04Gi scanned out of 168Gi at 33.6Mi/s, 1h24m to go
4.33Gi scanned out of 168Gi at 36.3Mi/s, 1h16m to go
6.36Gi scanned out of 168Gi at 35.8Mi/s, 1h16m to go
8.31Gi scanned out of 168Gi at 35.2Mi/s, 1h17m to go


Again, scrubs start with the newest data blocks by birth order, so a pool which has been exposed to writes (that includes an army atime updates, which your rsync likely created if you did not set the atime=off property; those will in turn have created new zfs metadata that will be checked first) will have relatively randomly laid-out blocks to check first, while a freshly rsynced pool will start with the last files copied nice-and-sequentially by your rsync.

IOPS limits Mi/s for scrubs; there are fewer IOPS available for more randomly laid-out blocks than for highly sequentially laid-out blocks.

Finally, scrubbing is a fairly rare operation, even if performed as regularly as monthly or even biweekly. Worrying about scrub performance seems to be wrong-headed. You might worry about the impact of a scrub on your usual use of the datasets one might expect to find in a pool called "Users", but as it's low priority, unless your pool performance is marginal in the first place, it should not be that much of a problem.

So the key questions are:

1. is the performance of "Users", when used normally, noticeably different from that of "Users2" when used in the same way ?

2. if "Users" performs noticeably less well, is the VASTLY greater data availability guarantees of a pool where all the storage vdevs have replication ("all" being "1" and "replication" being two-device degenerate raidz1) offset that?

Finally, do you know about "zfs send" / "zfs receive" ? That may be faster than your particular invocation of rsync, particularly if the --delete/--inplace flags are meaningful (e.g. because you're doing an incremental rsync). And *especially* if you're using rsync 2.x.

your explanation of mirror performance makes sense, but i see the
opposite: my single-disk pool is outperforming my mirror.

regardless of whether or not the other pool is being scrubbed, my
new pool scrubs at over 30MB/s, and my old pool, which scrubbed at
30MB/s when it was newly created, now scrubs at 15MB/s on a good
day. i know scrubbing isn't the holy grail of performance monitoring,
but i can tell you that my system has become close to unusable with
my old pool (as in i open a terminal window and i wait ten or twenty
seconds for zsh to parse my dotfiles, which, i admit, are getting
out of hand). unfortunately, there's no good performance metric i
can provide regarding 'logging in seems slow' or 'terminal windows
are slow to open.' scrubbing may be a lousy way to benchmark, but at
least it provides tangible numbers.

your final questions:

1. Users is always slower than Users2.

2. replication is a must-have.

3. yes, but speed isn't an issue here.

the rest of your message sort of implies i don't know my ass from
my elbow. that may be the case, but i came looking for answers, not
ridicule.

i guess the only way for me to test is to break my Users mirror,
create a new pool using one of the disks from Users, and benchmark
it against Users. again, i think it's silly that my zpools are
somehow 'degrading' over time, but i've seen this twice now.

hi graham,

i don't seem to be affected by reboots. i tried, no change. new pool is still dramatically faster than the old one. my pool(s) are used as my home directory, and with the new one, it is as usable as hfs+. with the old pool, i get beach balls inside apps and applications slow to open and all sorts of slow I/O behavior that makes zevo painful to use for a home dir. my old pool led to the first spinning beach ball inside a terminal window i have ever seen.

my old pool never hit 80% (that i know of) but every time i upgrade my pool i also increase the pool size, so it's possible the pool performance is dropping off as free space is reduced.

if scrubbing is a pol way to benchmark, what tare people using? i know traditional unix tools are of varying usefulness since you often wind up benchmarking the arc. i use scrubs because it's a useful way to compare pools, even if it's not a good way to measure outright performance numbers.

I'm sorry you think it's ridicule.

Nobody here has any visibility into your system other than what you communicate.

Also, you're not the only person likely to read posts in this thread.

a zpool raidz1 named Users, consisting of a pair of 250gb disks


vs.

NAME STATE READ WRITE CKSUM
Users ONLINE 0 0 0
mirror-0 ONLINE 0 0 0
GPTE_C7015CF8-E5EA-4C9E-93C9-B4A2190F7AFE ONLINE 0 0 0 at disk2s2
GPTE_EED64656-120D-49EF-86E8-E0A746061DC3 ONLINE 0 0 0 at disk1s2


That's actually a mirror vdev, not a raidz1.

The most likely reason why a mirror vdev will dramatically underperform vs a single disk vdev is if they are connected differently. If these are two USB2 external enclosures while your single-drive vdev is in a FW800 external enclosure, that would explain this degree of performance difference, for example.

What does "system_profiler -detailLevel mini" say ?

if scrubbing is a pol way to benchmark, what tare people using? i know traditional unix tools are of varying usefulness since you often wind up benchmarking the arc. i use scrubs because it's a useful way to compare pools, even if it's not a good way to measure outright performance numbers


It's *a* way, sure, but I don't agree that it's a useful one. Since the ARC is key to good performance of any zfs dataset, measuring it really does tend to be useful.

However, you can strip out its influence to a large degree:

Code: Select all
$ zfs create -o primarycache=none -o secondarycache=none -o sync=always -o logbias=throughput pool/testset
...do some benchmark in /Volumes/pool/testset ...
$ zfs destroy pool/testset

hello,

sorry, i just didn't need the primer on data redundancy or scrubbing, been using zfs since 2005. and, apparently, can't tell a mirror from a parity setup. i'm a moron. i only have single-disk vdevs or mirrors.

all disks in both pools are connected to the same ich10r controller.

i'll try messing with filesystems that don't cache.

here is stat and system_profiler output.

Re: performance degradation over time

That's OK, with a simple caveat: ZEVO developer testing is limited to Apple-branded hardware.

A hint: if you can switch to the full editor for future posts (or edition of your past posts), formatting of some areas as Code could make things easier to read. Columns and indents are particularly difficult to interpret when alignment and white space is lost.

(Only one downside: code is currently not indexed by the forum (but is indexed by Google [Bot]).)

Back to the essence of this topic … alongside the questions and observations offered by raattgift: is there compression=gzip-9 or anything comparably hungry in this history of the dataset(s) in the affected pool(s)?

For what it's worth: with my own setup, which is not optimised for performance, I suspect that occasional slowness – during scrub of a particular pool – is to be expected when 'going over' points in time where compression was greatest for blocks for a large compressible file (or for a succession of relatively small compressible files such as bands of a .sparsebundle).
