Input/output error

[Ronaldve]

Today I was running the pleskbackup program to make a full backup of everything. after a while I saw these messages:

Phase 2/2: packing data
/bin/tar: ./access_log.processed.1.gz: Cannot stat: Input/output error
/bin/tar: Error exit delayed from previous errors
/bin/tar: ./access_log.processed.1.gz: Cannot stat: Input/output error
/bin/tar: Error exit delayed from previous errors

On two domains I found access_log.processed.1.gz files with these characteristics:
size: 0kb
modified: Thu Jan 01 01:00:00 CET 1970
chmod: 0000
user: root
group: root

Any idea what's going on here?
Also I'm not able to delete these files as root. When I try I get an Input/output error.

It seems the file mode (0000) is the problem. That means no access for anyone. I don't know how those files got chowned to 0000, but as root you should be able to change the mode again.

Run chown 644 access_log.processed.1.gz in the dir where you found those files and you should be able to access them again.

When I try that i get this message:
chown: cannot access `access_log.processed.1.gz': Input/output error

Looks like file system corruption: http://www.eukhost.com/forums/showthread.php?t=979
