Subject: [PATCH 585/587] extras: Disable remote-dio in gluster-block profile
|
|
|
21ab4e |
|
|
|
21ab4e |
gluster-block file is opened with O_DIRECT but because block-profile has
|
|
|
21ab4e |
remote-dio enabled, it is leading to high latency for fsync which leads to
|
|
|
21ab4e |
failures in cassandra. Disabling remote-dio fixed this issue. We need to change
|
|
|
21ab4e |
remote-dio to disabled in gluster-block.
