Total system failure

Post by BillyPrefect » Sat Mar 02, 2013 9:33 am

Please help.
My system has failed completely. It has done this before when I have messed things up trying different sharing methods, I have rebuilt the OS and all was well. As soon as I installed Zevo the pool remounted itself. I would scrub and everything would show as all good. Yesterday the system failed completely complete kernel panic not able to start the OS. I attempted a Time Machine restore as I couldn't recall doing anything that would have corrupted the system. This didn't work so I reinstalled Mountain Lion.
I am able to load Mountain Lion without a problem as long as my drives from my pool are not attached. Everything is working fine, right up until I plug in my storage drives (3 X 3Tb).
I would just like the data back at this point. Is there any possibility of installing a different OS and being able to run an import on the pool possibly?
Zevo is at zpool 28, so if I were to install maybe Solaris or atleast run some live installer, would the up'ed version at 31 be able to work some sort of magic and let me at least try to scrub my data? I want to pull my pictures out really. I can find the video files again, all 4Tb if needed, I just know that I will not be able to download anything resembling my wedding pictures!
Any help at all would be very appreciated.

Details please

OK so in essence you have:

  • OSx86 with a working version of Mountain Lion that panics when a pool with some disks are used with a version of ZEVO.

Please provide the details suggested below, and anything else that might be relevant. Hint: use the full editor and for legibility, paste as code where appropriate.

The version of ZEVO Community Edition: 1.1 or 1.1.1. (Recall that the full installer does not provide the latest version.)

The version of Mountain Lion, and the build.

Makes and models of each disk drive, including those that are used for HFS Plus.

Makes and models of enclosures.

Connectivity.

Computer hardware.

In the days before the issue, did you keep any record of outputs from any of the following commands (or similar)?

Code: Select all
zfs list

zpool get all puddle

sudo zpool status -v puddle

zpool history puddle

sudo zdb -h puddle


If no recent records, then with a different OS – without the dynamic import of ZEVO – you could get relevant information.

Compatibility with other ZFS systems

I shouldn't rush to upgrade from ZFS pool version 28. First understand the nature of the issue.

Off-topic from ZEVO

How did the restoration fail? Understanding this might help to realise the bigger picture.

Thank you.
This is the first response.
Zevo 1.1.1 - It was up and running very stable for the month of February. Files were added to the pool on a regular basis. I believe I saved some screen shots of the zfs and zpool commands - I will look after I finish this first response.
Mountain Lion 10.8.2
Seagate 3Tb - 4K drives, built with the offset. Could that be the problem now? I am attempting to have Zevo simply fire up the pool, but it is crashing out due to not seeing the offset?? The drives are all ST3000DM001.
I took snapshots at least twice a week of the pool. I would also scrub again once a week - four weeks with a scrub action probably every Saturday night.
No enclosures. SATA 3Gbps internal from motherboard direct. Motherboard is gigabyte ep45-ud3p with a q6600 quad core 2.4Ghz processor. 8Gb ddr2. Mountain Lion has been running flawlessly since last october, went with zfs probably in January, and it has been working fine up until this incident. I started with 3 X 500G drives, rebuilt once I had my first 3Tb drive on boxing day when I realize the offset issue.
If I have the drives connected before I install zevo ML shows unreadable drives, once I install Zevo the system kernel panics.

kernel panic

Post by grahamperrin » Sun Mar 03, 2013 10:50 am

Thanks, if you can please paste (as code) the content of the most recent .panic file. I'd like to see whether it's comparable to one or more in another topic.
