Subject: [PATCH 101/104] tier/dht: check for rebalance completion for EIO error
|
|
|
12a457 |
|
|
|
12a457 |
When an ongoing rebalance completion check task been
|
|
|
12a457 |
triggered by dht, there is a possibility of a race
|
|
|
12a457 |
between afr setting subvol as non-readable and dht updates
|
|
|
12a457 |
the cached subvol. In this window a write can fail with EIO.
