Hello All, I am experiencing the same problem as described in this thread: https://www.redhat.com/archives/linux-cluster/2004-July/msg00145.html The cluster is setup with two nodes. One one of the nodes whichever runs lock_gulmd is able to mount GFS file systems. Initially I didn't run lock_gulmd on the second node which is not mater but later after reading this posts I started it and got the same error message: lock_gulmd[18399]: You are running in Standard mode. lock_gulmd[18399]: I am (clu2.abc.com) with ip (192.168.11.212) lock_gulmd[18399]: Forked core [18400]. lock_gulmd_core[18400]: ERROR [core_io.c:1029] Got error from reply: (clu1:192. 168.11.211) 1006:Not Allowed Has anyone solved this problem before.
