Hi.
Â
I have a file server that has had 2 xfs Kernel trace dumps about 2 weeks apart.ÂÂ
Â
The RAID 60 data store is mounted as /home with xfs as the file system. The /home space isÂshares viaÂNFS exportÂandÂCIFS share. At the time of theÂTrace dumpsÂNFS access hangs and crashed users sessions on the client side.ÂÂTheÂoutputÂof the last traces is below.Â
Â
Can you advise as to the causeÂof this dump and possible resolution ?ÂÂÂ
Â
System information:

CentOS release 6.5 (Final)

Intel(R) Xeon(R) CPUÂÂX5560Â @ 2.80GHz
