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?
Yes, that looks right.
