Subject: [PATCH 447/450] cluster/ec: Don't update trusted.ec.version if fop
|
|
|
887953 |
succeeds
|
|
|
887953 |
|
|
|
887953 |
If a fop has succeeded on all the bricks and trying to release
|
|
|
887953 |
the lock, there is no need to update the version for the
|
|
|
887953 |
file/entry. All it will do is to increase the version from
|
|
|
887953 |
x to x+1 on all the bricks.
|
|
|
887953 |
|
|
|
887953 |
If this update (x to x+1) fails on some brick, this will indicate
|
|
|
887953 |
that the entry is unhealthy while in realty everything is fine
|
|
|
887953 |
with the entry.
|
|
|
887953 |
|
|
|
887953 |
Avoiding this update will help to not to send one xattrop
|
|
|
887953 |
at the end of the fops. Which will decrease the chances
|
|
|
887953 |
of entries being in unhealthy state and also improve the
|
|
|
887953 |
performance.
