update only running "zpool scrub -s test1" stops kernel message errors. |
|
when the errors begin, zpool status output appears stalled, ie running it again shows no modification of "scanned" or percent. only the speed decreases (because is the average and "zero" decreases de average) pool: test1 errors: No known data errors |
|
These warnings were addressed in the 0.6.0.76 Ubuntu release. I see you have 0.6.0.78 installed but the older modules must have been loaded. I'd suggest you update to the latest daily source, reboot your machine, ensure the 0.6.0.78 (or newer) modules get loaded and try again. |
|
I am afraid this has happened with .78: note the logs are timestamped Sep 18 13:11:01 while the module has been loaded earlier: root@homerouter:~# fgrep ' module v0.6.0.' /var/log/messages nonetheless, I'll retest now with this latest verson. |
|
Yes, please do. If your able to recreate the issue we'll absolutely reopen the bug and get it fixed. |

stalled at 5 percent scan: scrub in progress since Wed Sep 19 20:53:34 2012 do you want me to wait for 100% or shall I cancel the scrub and send what's been dumped so far? |
|
Can you check the console via |

it eventually finished - dump truncated at 10Mb, hope it's long enough: http://dl.transfer.ro/transfer_ro-19sep-26074c8905.zip 0.6.0.80-0ubuntu1~oneiric1 |
This warning indicates the incorrect use of KM_SLEEP in a call path which must use KM_PUSHPAGE to avoid deadlocking in direct reclaim. See commit b8d06fc for additional details.

@mailinglists35 Your right, you found a few new cases of this related to dedup. The above patch should fix it, you can either roll a custom version or wait a few days for this to make it in to the daily PPA. |
|
thank you, i'll just wait for normal update and report status. |
|
I waited and waited for this patch to get into a new daily ppa build but eventually I gave up and downloaded zfsonlinux-spl-a6c6839 & ran "autogen.sh; configure; make" for the first time in years. this was tested on ubuntu precise amd64 |
|
According to the attached log you loaded the Ubuntu v0.6.0.80-rc11 modules not the latest master source with the fix. |
|
scrub messages appears to have stopped once I updated to the latest ubuntu-zfs package, thanks. |
|
is this related, or is another bug? maybe related to openzfs/spl#97? using latest ubuntu-zfs package on ubuntu 12.04 lts amd64 errors: No known data errors kernel: Oct 11 18:24:27 mailhost kernel: [ 1965.517305] VERIFY(!RW_LOCK_HELD(&l->l_rwlock)) failed |
|
referenced log file /tmp/spl-log.1349969067.337 |
|
Yes, your second issues certainly looks like openzfs/spl#97 . So it's a different bug. |

at the time of output I was trying to stress snapshots.
i first created about 200 snapshots then while creating new ones I started to randomly delete previous:
"while true; do zfs-auto-snapshot -p$(uuidgen) //; zfs destroy $ (let "snap = $RANDOM % $ (zfs list -H -o name -t snap|wc -l)"; zfs list -H -o name -t snap|head -n $snap|tail -n1); done"
during this I started a cp from dir1 to dir2 inside a zfs filesystem.
then during this madness I started zpool scrub :)
at some point I noticed these kernel messages.
