Re: Graceful shutdown doesn't stop all Gluster processes

Basically the lvm operations on the iSCSI target are online, and then on the client rescan the lun: 'iscsiadm -m node --targetname target_name -R and then just extend the FS.Of course, test the procedure before doing it in production.

Why do you use glusterFS on iSCSI ? You can have a shared file system on the same lun and mounted on multiple nodes.

Gluster is supposed to be used with local disks in order to improve resilience and scale to massive sizes.

Hi Strahil,

In our setup, the Gluster brick comes from an iSCSI SAN storage and is then used as a brick on the Gluster
 server. To extend the brick, we stop the Gluster server, extend the logical volume (LV) on the SAN server, resize it on the host, mount the brick with the extended size, and finally start the Gluster server.

Please let me know if this process can be optimized, I will be happy to do so.

Many thanks,

Anant

Hi Anant,

why would you need to shutdown a brick to expand it ? This is an online operation.
