Permanent errors on replicated pool

[alexg]

bk-tank is my replication pool and consists of a single disk. My primary pool is "tank" and raidz-2. I can always recreate bk-tank and I have another offline backup.
Is there a way to clear these errors from replication pool or do I need to start from scratch?

Code:

  pool: bk-tank
state: ONLINE
status: One or more devices has experienced an error resulting in data
        corruption.  Applications may be affected.
action: Restore the file in question if possible.  Otherwise restore the
        entire pool from backup.

You can delete those offending files.

Keep in mind that these errors usually mean that your disk is failing. I'd consider destroying the pool and recreating it from your backup.

That is, assuming your backup doesn't have those files in their "now corrupted" state.

Running long test now. My primary pool looks good.

Will replication detect that it needs to replicate these files?

You mean if you are replicating from your primary pool to bk-tank? I don't think so. The whole expectation with ZFS is that you either:

1. Don't care about file consistency.
2. Use a pool with redundancy to ensure that any corruption can be repaired.

You've chosen #1 since you clearly didn't use a pool with redundancy.
