cache/log/spare devices are treated differently, but AIUI special devices should just have the normal rules for other data vdev behavior.

3 years ago Here is an example. The host zfs3 is able to see raidz3 devices from the pools home1 and home3, but there is no indication that it can't see the special devices that are part of those pools as seen from the hosts cascade2 and zfs4 that currently have those pools imported. Note, zfs3 is running version 2.1.1 on Rock Linux 8.4.

errors: No known data errorsIf I had to guess what's happening...
Normally, it does try to print special vdevs that it found:
Or tell you if it knows there are more vdevs that it didn't find:
But the latter wouldn't happen if reason was ZPOOL_STATUS_HOSTID_REQUIRED, which it had to be for you to get the MMP error in the first place. Maybe you could munge up the config after getting that back to go try the import again with the multihost status fudged to be ignored?

3 years ago As a first test I ran zgenhostid, but that didn't make a difference. I will take a look at setting up a non-production pool to see what happens with MMP disabled.

sdfc ONLINEHere is another example where the host zfs1 does not report unaccessible special devices from the home4 pool that is currently imported on another system (zfs2). Note, zpool import reports the pool as FAULTED even though it is state: ONLINE with no errors on the system where it is active. Perhaps the missing devices are trigging the state: FAULTED? Or this may the result of zfs2 running ZFS version 2.1.1 and zfs1 version 2.0.5?
Not sure what to test next, but I can export and re-import this home4 pool to run additional tests if that would be helpful?
[root@zfs1 ~]# zpool import
pool: home4
id: 7815774519246331192
state: FAULTED
status: The pool was last accessed by another system.
action: The pool cannot be imported due to damaged devices or data.
The pool may be active on another system, but can be imported using

Describe the feature would like to see added to OpenZFS
zpool importwith no pool specification should report whether discovered pools withspecialdevices could be importedHow will this feature improve OpenZFS?
This would facilitate checking HA setups to confirm that all hosts can see all the necessary devices before they actually need to import a pool.
Additional context
I think it would also be helpful to report on the accessibility of
logandcachedevices as well.
