Hi list, Is it normal for a fresh install that CLVM says that the locking is disabled while locking_type is set to 3 in lvm.conf ?
[root@myhost ~]# clvmd -d CLVMD[e2bd6170]: May 18 12:42:24 CLVMD started CLVMD[e2bd6170]: May 18 12:42:24 Connected to CMAN CLVMD[e2bd6170]: May 18 12:42:24 CMAN initialisation complete CLVMD[e2bd6170]: May 18 12:42:25 DLM initialisation complete CLVMD[e2bd6170]: May 18 12:42:25 Cluster ready, doing some more initialisation CLVMD[e2bd6170]: May 18 12:42:25 starting LVM thread CLVMD[e2bd6170]: May 18 12:42:25 clvmd ready for work CLVMD[e2bd6170]: May 18 12:42:25 Using timeout of 60 seconds CLVMD[42aa8940]: May 18 12:42:25 LVM thread function started File descriptor 5 (/dev/zero) leaked on lvm invocation. Parent PID 6240: clvmd WARNING: Locking disabled. Be careful! This could corrupt your metadata. CLVMD[42aa8940]: May 18 12:42:25 LVM thread waiting for work I guess it's related to this following warning when trying to list the vg's (while clvmd is up) : [root@myhost ~]# vgs connect() failed on local socket: No such file or directory WARNING: Falling back to local file-based locking. Volume Groups with the clustered attribute will be inaccessible. VG #PV #LV #SN Attr VSize VFree vg00 1 7 0 wz--n- 24.28G 10.44G This prevents me from creating a clustered VG (actually I can create a clustered VG, but not the LV inside). [root@myhost ~]# vgcreate -c y vggfs01 /dev/sdb2 connect() failed on local socket: No such file or directory WARNING: Falling back to local file-based locking. Volume Groups with the clustered attribute will be inaccessible.

Volume Groups with the clustered attribute will be inaccessible. Skipping clustered volume group vggfs01 [root@myhost ~]# The final goal is to build a GFS shared storage between 3 nodes. The cman part seems to be OK for the three nodes : [root@lhnq501l ~]# cman_tool services type level name id state fence 0 default 00010001 none [1 2 3] dlm 1 rgmanager 00020003 none [1 2 3] dlm 1 clvmd 00010003 none [1 2 3] This is my first RHEL cluster, and I'm not sure where to investigate right now. If anyone has ever seen this behaviour, any comment is appreciated, Thanks, - Ben.
