[Ocfs2-users] Recreated FS - getting "no free slots available" message when trying to mount
Had to recreate one of eight OCFS2 filesystems normally mounted by six
identical servers running Slackware 11.0 + open-iscsi + ocfs2-tools.
Used this command:
mkfs.ocfs2 -L je111 -N 6 /dev/sde1
Now, when I attempt to mount the new file system, I get this (from dmesg):
OCFS2 Node Manager 1.3.3
OCFS2 DLM 1.3.3
OCFS2 DLMFS 1.3.3
OCFS2 User DLM kernel interface loaded
ocfs2_dlm: Nodes in domain ("E8739DF804DF48A693DC984C96AD63E6"): 2
OCFS2 1.3.3
ocfs2_dlm: Nodes in domain ("51D68831F9E44A9FAC939AA8A45A48F3"): 2

(3443,1):ocfs2_mount_volume:1090 ERROR: status = -22
ocfs2: Unmounting device (8,65) on (node 2)
No problems mounting and umounting several previously created FSs with
prior generation of ocfs2-tools. Normal dmesg excerpt:
ocfs2_dlm: Nodes in domain ("9A383D91EC2149E5AF519FBE871852C7"): 2
kjournald starting. Commit interval 5 seconds
ocfs2: Mounting device (8,81) on (node 2, slot 0) with ordered data mode.
Various kernels tried including 2.6.20.13, 2.6.20.15, 2.6.21.5, 2.6.21.7
The 2.6.20 kernels had this patch applied:
http://www.kernel.org/pub/linux/kernel/people/mfasheh/ocfs2/backports/2.6.20/ocfs2_2.6.20_fixes-20070502-1.patch
The 2.6.21 kernels had this patch applied:
http://www.kernel.org/pub/linux/kernel/people/mfasheh/ocfs2/backports/2.6.21/ocfs2_2.6.21_fixes-20070502-1.patch
Any clues or hints what to try next?
I even went so far as to dd </dev/zero >/dev/sde1 to wipe out the
1.8tb partition before rerunning the mkfs.ocfs2 command.
Thanks, Rich B

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.

Can you use the packages provided on oss.oracle.com. The issue is strange and I would like to rule out a build error.
