Here is the situation:
We have a file server that is not saving timestamps to a small portion of its files (77 files out of serveral million). It instead writes a default mtime of 1969-12-31 19:00 (unix epoch).
When this does happen, it happens irregularly with no set pattern (ie. one file here, a group of files in the same directory there. etc.) The files that are timestamped this way have been uploaded to the server through NFS.
It should be noted that we are only seeing this happen in an NFS share that is on this server and it has not happened to any of the servers system files, it seems isolated to just the NFS share.
Some additional info:
- the server is running Ubuntu Server 9.04
NFSv4 for file serving. Here is the exports line:
- We recently migrated our files to this server using rsync from our old file server
- This server has a hardware RAID 5 array using a 3ware 9650SE controller.
- Filesystem is ext3 with LVM and LUKS/DMCRYPT on a single root partition
- The server is regularly syncing its time with ntpd.
Updated the filesystem and partitioning info above as requested in comments.
