zpool status says there are errors, but won't say what they are #79

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Have a 77.0.9 system that kernel panics approximately every day (seriously 
driving me insane)
2. Presumably one of those kernel panics caused some corruption
3. Run zpool status -v

What is the expected output? What do you see instead?
The list of errors actually available is expected, instead:

root@cole:/Users/patrick# zpool status -v
  pool: Apathy
 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.
   see: http://www.sun.com/msg/ZFS-8000-8A
 scrub: none requested
config:

    NAME         STATE     READ WRITE CKSUM
    Apathy       ONLINE       0     0     0
      raidz1     ONLINE       0     0     0

        disk4s2  ONLINE       0     0     0
        disk5s2  ONLINE       0     0     0
      raidz1     ONLINE       0     0     0
        disk2s2  ONLINE       0     0     0
        disk3s2  ONLINE       0     0     0
        disk1s2  ONLINE       0     0     0

What version of the product are you using? On what operating system?
77.0.9 on 10.6.5 (I'm very wary of trying to install 10.6.6 when it can kernel 
panic at any moment)

Please provide any additional information below.
n/a

77.0.9 is a developer release which has known problems; it's not for general 
use. You should use MacZFS 74.0.1 if you want a stable system (but please 
ensure that you delete the /System/Library/Frameworks/zfs.kext and 
/System/Library/Filesystems/zfs.util directories before re-installing; there 
are some issues with using the installer to downgrade).

As for the file, I'm not sure why it's not showing the list of files. Does a 
zpool scrub help find the file?

74.0.1 has show stopper bugs for me (after writing ~10GB the file system would 
just stop responding), which is why I upgraded to 76.(whatever it was).

I tried downgrading to 76, but after doing so the file system didn't appear 
(zfs/zpool status showed no volumes).

Doing a zpool scrub on this FS (which currently has 5.3TB of data on it) takes 
a couple of days, so not sure I could complete a scrub before a kernel panic 
would take down the machine. Would zpool scrub continue, or would it need to be 
restarted?

MacZFS has been discontinued.  Please switch to https://openzfsonosx.org/
