[Ocfs2-users] Recreated FS - getting "no free slots available" message when trying to mount

[Sunil Mushran]

Do:
# debugfs.ocfs2 -R "stats" /dev/sdX
Ensure the Number of Slots is what it is supposed to be.

Also, do:
# debugfs.ocfs2 -R "ls -l //" /dev/sdX
Ensure you see the journals for all the above slots.
