FreeNAS ZFS Kernel Panic

kernel-panic zfs freenas

I'm running FreeNAS 8 and my computer had a hard reset from a power outage and now every time I try to boot I get the following error message:

Error Message: panic: zfs_replay_acl_v0:898: unsupported condition

I am running ZFS with ZFS filesystem version 4, ZFS storage pool version 15. Any ideas on how to fix this?


You could use the live option of the FreeBSD media(shell) and try to create a new zfspool.cache.

I don't know how the internals of FreeNAS are, but once you could find the pool, it is just to create another zfspool.cache. Just don't forget to backup your current zfspool.cache.

Use the command fmdump -eV to figure out what could be the software root cause of this crash
