You can do this:

1. 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. Activate the gluster domain (via engine)

The domain should become active after a while.


David: can you confirm this is the best way to reconstruct the ids file?
