Hi, I'm having a problem on CentOS 6.5 with a two-node cluster for HA NFS. Here's the cluster.conf: http://pastebin.com/aVAuUDtc The cluster nodes are VMware guests. Occasionally the node providing the NFS service has a problem accessing the disk device (I'm working with VMware on that...), but long story short -- the kernel shuts down the XFS filesystem: Apr 25 02:29:51 sdo-dds-nfsnode2 kernel: XFS (dm-10): metadata I/O error: block 0x170013a900 ("xlog_iodone") error 5 buf count 65536 Apr 25 02:29:51 sdo-dds-nfsnode2 kernel: XFS (dm-10): xfs_do_force_shutdown(0x2) called from line 1062 of file fs/xfs/xfs_log.c. Return address = 0xffffffffa027f131 Apr 25 02:29:51 sdo-dds-nfsnode2 kernel: XFS (dm-10): Log I/O Error Detected. Shutting down filesystem Apr 25 02:29:51 sdo-dds-nfsnode2 kernel: nfsd: non-standard errno: 5 Apr 25 02:29:51 sdo-dds-nfsnode2 kernel: XFS (dm-10): Please umount the filesystem and rectify the problem(s) rgmanager noticed the filesystem problem (see log at http://pastebin.com/mPPBP2HY ), and marked "HA_nfs" service in a failed state. What I'm confused about is why the fencing is not taking place in the above scenario. I'm guessing I have either a misunderstanding or misconfiguration. At this point I'd like the other node to fence the failed one and take over. Or, the failed node to fence itself. I've tested fencing from the command line and it works: fence_vmware_soap --ip 192.168.50.9 --username ddsfence --password secret -z --action reboot -U "423d288c-03ff-74bf-9a4f-bf661f8ed87b" I'd appreciate any help with this. package versions, if it matters: rgmanager-3.0.12.1-19.el6.x86_64 cman-3.0.12.1-59.el6_5.2.x86_64 -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Robert Jacobson Robert.C.Jacobson@xxxxxxxx Lead System Admin Solar Dynamics Observatory (SDO) Bldg 14, E222 (301) 286-1591 -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
