So, I am off sick and my colleagues decided to load test our set of five
servers excesively. All ran out of swap. So far so irritating, but whats has
happened is that twoof them now will not boot, as it appears the ZFS pool
they are booting from has become corrupted.
One starts to boot, then crases importing the root pool. The other doenst
even get that far with gptzfsboot saying it can't find the pool to boot from!
Now I can recover these, but I am a bit worried, that it got like this at
all, as I havent ever seen ZFS corrupt a pool like this. Anyone got any
insights,
or suggstions as to how to stop it happening again ?
We are swapping to a separate partition, not to the pool by theway.
Good.
Try downloading live disc or mfsBSD and importing pool r/o from there.
zpool import -N -O readonly=on -f -R /mnt/somezpoool
If that doesn't help try:
zpool import -N -O readonly=on -f -R /mnt/somezpoool -Fn
Drop us a line of your configuration and used ZFS features. Like dedup,
snapshots, external l2 logs and caches.
