CFS umount abnormally
Created: 10 Dec 2012 | 3 comments
I have ten SFCFS nodes on the same version of AIX OS platform with SFRAC 5.1SP1RP3. This SFCFS cluster has two CFS resources which running on all nodes.Recently, I encounter a very strange problem for service group sg-cfs-mount01 on a specific node.(DB2) The resource cfsmount1 related to service group sg-cfs-mount01 was offlined abnormally. I have checked in engine_A.log and there are shown I/O test failure by CVMVolDg agent.Then I also checked SYS logs, dmpevent.log .. etc. but there are no related errors.This problem only occurs on node DB2 with SG sg-cfs-mount01,but the SG sg-cfs-mount01 on other nodes and SG sg-cfs-mount02 on all nodes (include DB2) is working normally.(This is what I think strange for)
I attached engine_A.log CFSMount_A.log CVMVolDg_A.log etc.. in logs.tar
Thanks in advance.
