hello, recently I remove-brick from the 1×3 DHT volume. Using vdbench, which is io test tool，It was terminated because the file could not be found when remove-brick is commited at the nfsv3 mountpoint

client: nfs-ganesha v3
From /var/log/ganesha/ganesha-gfapi.log, I found some info as follow:

From rebalance log, I found some info as follow:

A problem has arisen， At 17:53:49, f9054.file'rebalance has completed, it should update the cache subvol from wkvol03-client-18 to wkvol03-client-17.
But after rebalance, at ganesha-gfapi.log it still lookup use the old subvol name wkvol03-client-18. As the result, wkvol03-client-18 has been removed, lookup occurs problem
