Dear List, I'm running a Rhel 6.4 cluster and periodically i'm unable to mount some volumes. The volumes are iSCSI attached and clvm confirms them to be healthy and reachable.
The mount fails, actually just hangs. The failing volumes have the"blocked,join" status. Any ideas on how to unblock these specific volumes without rebooting the whole cluster ? root@node12:~# uname -a Linux node12 2.6.32-358.18.1.el6.x86_64 #1 SMP Fri Aug 2 17:04:38 EDT 2013 x86_64 x86_64 x86_64 GNU/Linux root@node12:~# group_tool fence domain member count 6 victim count 0 victim now 0 master nodeid 3 wait state none members 1 3 10 11 12 16 dlm lockspaces name disk10-thin id 0xbcc604bc flags 0x00000008 fs_reg change member 4 joined 1 remove 0 failed 0 seq 1,1 members 3 10 11 12 name clvmd id 0x4104eefa flags 0x00000000 change member 6 joined 1 remove 0 failed 0 seq 4,4 members 1 3 10 11 12 16 gfs mountgroups name disk10-thin id 0x8016e569 flags 0x00000008 mounted change member 3 joined 1 remove 0 failed 0 seq 1,1 members 10 11 12 name cluster4_disk8 id 0xef70c9dc flags 0x00000005 blocked,join change member 5 joined 1 remove 0 failed 0 seq 3,3 members 3 10 11 12 16 name disk2 id 0xe1c9eb17 flags 0x00000005 blocked,join change member 3 joined 1 remove 0 failed 0 seq 1,1 members 3 11 12
