[lustre-discuss] FLR mirroring on 2.12.1-1

[John Doe]

After mirroring a file , when one mirror is down, any reads from a client
just hangs. Both server and client are running latest 2.12.1-1. Client
waits for ost idx 1 to come back online.  I am only unmounting ost idx1 not
ost idx 7.

Has anyone tried this feature?

Thanks,
John.
