Hello list,
I have two-head ZFS setup with external disk enclosure over SAS expander.
This is a failover setup with CARP and devd triggering spool export/import.
One of two nodes is preferred master.
Then master is rebooted, devd kicks in as of CARP becomes master and the second node picks up ZFS-disks from external enclosure.
Then master comes back, CARP becomes master, devd kicks in and pool gets exported from the second node and imported on the first one.
However, I have experienced metadata corruption several times with this setup.
Note, that ZIL(mirrored) resides on external enclosure. Only L2ARC is both local and external - da1,da2, da13s2, da14s2
root@nfs2:/root # zpool import
pool: jbod
id: 17635654860276652744
state: FAULTED
status: The pool metadata is corrupted.
action: The pool cannot be imported due to damaged devices or data.

config:
