Subject: [PATCH 539/539] extras: disable lookup-optimize in virt and block
|

groups
|
|
|
14f8ab |
|
|
|
14f8ab |
lookup-optimize doesn't provide any benefit for virtualized
|
|
|
14f8ab |
environments and gluster-block workloads, but it's known to cause
|
|
|
14f8ab |
corruption in some cases when sharding is also enabled and the volume
|
|
|
14f8ab |
is expanded or shrunk.
|
|
|
14f8ab |
|
|
|
14f8ab |
For this reason, we disable lookup-optimize by default on those
|
|
|
14f8ab |
environments.
