I'm believe this is because the data center has a status of Non responsive (because a host cannot connect to storage or start SPM). The only option available on the gluster storage is activate. I have put all the hosts into maintenance. Is this enough to continue with the initialize lockspace step?

Put the gluster domain to maintenance (via engine) No host should access it while you reconstruct the ids file 2. Mount the gluster volume manually mkdir repair mount -t glusterfs <server>:/<path> repair/ 3. Create the file: touch repair/<sd_uuid>/dom_md/ids 4. Initialize the lockspace sanlock direct init -s <sd_uuid>:0:repair/<sd_uuid>/dom_md/ids:= 0 5. Unmount the gluster volume umount repair 6.
