Hi.
I have a CentOS 6.2 virtual machine in a vmware ESXi 4.0 host 4G Ram 4
virtaul cpus and with about 4 TB of disk space formatted with XFS .
I'm seeing a lot of :
Mar 21 10:49:42 nzhmlfpr05 kernel: XFS (dm-4): xlog_space_left: head behind tail
Mar 21 10:49:42 nzhmlfpr05 kernel: tail_cycle = 129, tail_bytes = 20163072
Mar 21 10:49:42 nzhmlfpr05 kernel: GH cycle = 129, GH bytes = 20162880
Mar 21 10:49:42 nzhmlfpr05 kernel: XFS (dm-7): xlog_space_left: head behind tail
Mar 21 10:49:42 nzhmlfpr05 kernel: tail_cycle = 5, tail_bytes = 333417984
Mar 21 10:49:42 nzhmlfpr05 kernel: GH cycle = 5, GH bytes = 333417792
Mar 21 10:49:42 nzhmlfpr05 kernel: XFS (dm-7): xlog_space_left: head behind tail
Mar 21 10:49:42 nzhmlfpr05 kernel: tail_cycle = 5, tail_bytes = 333417984
Mar 21 10:49:42 nzhmlfpr05 kernel: GH cycle = 5, GH bytes = 333417792
What would casue this ? A quick google , I found a post that indicated
I should unmount and mount the file systems. I have live production
data on this machine so I need to be careful. What is the best
solution ?
Thanks
Greg
