[Gluster-users] [Gluster-devel] Multiple Geo Rep issues due to SELINUX on CentOS 8.3

[Srijan Sivakumar]

Hi Strahil,

Selinux policies and rules have to be added for gluster processes to work
as intended when selinux is in enforced mode. Could you confirm if you've
installed the glusterfs-selinux package in the nodes ?
If not then you can check out the repo at
https://github.com/gluster/glusterfs-selinux.

Regards,
Srijan
