child corrupted

Post by BillyPrefect » Sat Feb 02, 2013 11:59 am

LOL. I just like the title.
I have a pool I called puddle, mounted in Volumes, I have no originality while experimenting.
One of the children, pool/MovieShare is now empty since last night.

zpool status shows...

pool: puddle
state: ONLINE
status: One or more devices has experienced an error resulting in data
corruption. Applications may be affected.
action: Restore the file in question if possible. Otherwise restore the
entire pool from backup.
scan: scrub in progress since Sat Feb 2 10:40:23 2013

zfs list shows...
NAME USED AVAIL REFER MOUNTPOINT
puddle 775Gi 140Gi 91.9Ki /Volumes/puddle
puddle/DocShare 31.4Gi 140Gi 31.4Gi /Volumes/puddle/DocShare

puddle/WorkOutShare 35.4Gi 140Gi 35.4Gi /Volumes/puddle/WorkOutShare

here is the annoying part...

theserver:/ admin$ ls /Volumes/puddle/MovieShare
theserver:/ admin$

That is the output... shows empty, blank. zfs list though shows what is was last night, around 20Gb.
I do have this to work with
theserver:/ admin$ zfs list -t snapshot

puddle/DocShare@jan31 235Ki - 31.4Gi -
puddle/MiscShare@jan31 361Ki - 186Gi -

puddle/MusicShare@jan31 202Ki - 15.5Gi -

puddle/TVShare@jan31 263Mi - 460Gi -
puddle/WorkOutShare@jan31 186Ki - 35.4Gi -
theserver:/ admin$

It would be down maybe a movie, just one if any, and I can live with that.
I would very much appreciate any help in restoring, I have tried a couple different threads but I am not getting anywhere.

result of ls

Suspect a mount point conflict. In lieu of

Code: Select all
ls /Volumes/puddle/MovieShare


try:

Code: Select all
ls -al /Volumes/puddle/MovieShare

Output from zpool status commands

Post by grahamperrin » Sat Feb 02, 2013 9:49 pm

That's probably corruption of just a little data.

Not corruption of the child file system.

Please run the following command:

Code: Select all
sudo zpool status -v puddle


If there's nothing sensitive or confidential in the output, please paste it to this topic.

Hint: use the full editor, paste as code.

What I think I did was create my own grief by hammering at it with different permissions from various sources. I rethought my whole process... also I rebuilt my entire system, reinstalled the OS then Zevo, and there was my vdev all safe and sound.
This time around I haven't bothered to install the server.app component of the OS. I am going to try with just Mountain Lion and SMBup running. I think this should work for me without any added grief.
