The only way to fix it is to (a) add redundancy to both 4 & 5, or (b) destroy and recreate the pool, and this time be very careful that you mirror 4 & 5.

What does that show?

You accidentally added 4 & 5 without mirroring.Not true. 4 & 5 may have been added initially as a mirror, then 5 detached from the mirror and later added as a single drive (rather than reattached to 4 as a mirror again). It can be easy to confuse "add" and "attach" commands.> The only > way to fix it is to (a) add redundancy to both 4 & 5Yes, attach 2 new disks, one to each of 4 and 5, to turn those vdevs (back) into mirrors.>, or (b) destroy and > recreate the pool, and this time be very careful that you mirror 4&5.Unfortunately, yes, if you can''t attach more disks, this is necessary, since it''s not currently possible to remove a top-level vdev. -- Dan. -------------- next part -------------- A non-text attachment was scrubbed...
