To enable shared storage I used next command:
# gluster volume set all cluster.enable-shared-storage enable
But it seems that it doesn't create gluster_shared_storage automatically.
# gluster volume status gluster_shared_storage
Volume gluster_shared_storage does not exist
Do I need to manually create a volume "gluster_shared_storage"? Do I
need
to manually create a folder "/var/run/gluster/shared_storage"? Do I
need to
manually mount it? Or something I don't need to do?
If I use 6 cluster nodes and I need to have a shared storage on all of them
then how to create a shared storage?
It says that it have to be with replication 2 or replication 3. But if we
use shared storage on all of 6 nodes then we have only 2 ways to create a
volume:
1. Use replication 6
2. Use replication 3 with distribution.
Which way I need to use?
Sincerely,
Alexandr
