Massive I/O errors on virtual machine using shared NFS
I'm not sure what information you need but here's what I'm experiencing:
Running Cpanel as a virtual machine under XenServer 6.2 and using a ReadyNAS 314 (Raid 10) as shared storage. ReadyNAS running firmware 6.1.8
A few days ago, Cpanel became unaccessible. When checking the console using Xencenter, I saw massive I/O errors. Rebooting the VM took me to maintenance mode (Centos 6.4) where I ran fsck. After fixing numerous errors, I rebooted and everything came back up normal with all mounts as RW. After about 4 or 5 hours, it went down again with I/O errors and fsck did not fix the problems. After rebooting the NAS and running fsck again, I was able to successfully boot the machine with drives in RW mode. This time it ran for about 12 hours before crashing.
Long story short, this went on for two days and now fsck is not fixing the problem. In addition, when I mount one of the NAS NFS shares onto another Linux machine, I'm getting a "No space left on device" error when trying to copy between folders even though there is 1.2TB free space on the share.
df -h shows: 192.168.50.67:/data/Backup 3.7T 2.5T 1.2T 67% /mnt/Backup
For right now, I'm getting all of my files off of the shared NAS and putting them on local storage repositories?
Thank you in advance for any suggestions,
Dan
