Hi,

I went on the particular server on which the file in question
resides.  I check the RAID and all the disks show up as OK.
I looked in dmesg and did not see anything on xfs.  To confirm
this absence, I did "grep -in xfs dmesg" and that also came
up empty. "grep -in fs dmesg" (no "x") returns

161:checking if image is initramfs... it is
196:usbcore: registered new driver usbfs
256:VFS: Disk quotas dquot_6.5.1
453:EXT3-fs: mounted filesystem with ordered data mode.
