Subject: [PATCH 457/473] extras: Provide group set for gluster-block workloads
|
|
|
21ab4e |
|
|
|
21ab4e |
For gluster-block workloads I/O is always with o-direct so it doesn't
|
|
|
21ab4e |
benefit by any of the perf xlators so disabling all of them to save
|
|
|
21ab4e |
on memory.

We want the I/O on the file to be with o-direct

VM workloads which is very similar to gluster-block

ports that are > 1024 in tcmu-runner are allowed.
