attempt to access beyond end of device
Posted on 2008-10-22
A list below is what we have been experiencing over and over again. I am not sure if it is a bad hard drive or something with the 3ware raid card.
The first thing that happens is a file shows up on the file system that is about 6.2 PetaBytes. This is impossible because the raid is only 182GB
Second, are backup server tries to backup this 6.2 PT file. It continuously tries to back it up until someone finally has to stop it. I guess it would backup until the backup server drive is full.
Third, the log shows
Oct 22 04:03:02 fs kernel: attempt to access beyond end of device
Oct 22 04:03:02 fs kernel: sda2: rw=0, want=6736695736, limit=386427510
This makes perfect since because the file is not really there.
The last thing that happens is the file system will finally switch over to read only mode. We then have to reboot the server. On reboot FSCK always says the drive contains errors. FSCK then goes though and fixes a lot of inode problems.
Any ideas on why the big 6.2 PT file would keep being created and how we could stop it?
This is a raid 1 with two 186.31 GB WD drives. This is an ext3 filesystem.
