Weird DF Output

Hello,

We have a monitoring system set up to make sure our /tmp usage isn't being exceeded on our webserver. All of a sudden DF is now showing this output:

Code:

Filesystem            Size  Used Avail Use% Mounted on
/dev/scsi/host0/bus0/target0/lun0/part1
                       14G  126M   13G   1% /
/dev/scsi/host0/bus0/target0/lun0/part6
                       49G  403M   46G   1% /home
/dev/scsi/host0/bus0/target0/lun0/part8
                       21G  -64Z   20G 101% /usr
/dev/scsi/host0/bus0/target0/lun0/part7
                       49G  2.8G   44G   6% /var

The /dev/scsi part has always been normal, but for the /usr partition, the used amount is showing up really weird. Even more strange is the output from "df -H"

Code:

Filesystem             Size   Used  Avail Use% Mounted on
/dev/scsi/host0/bus0/target0/lun0/part1
                        15G   132M    14G   1% /
/dev/scsi/host0/bus0/target0/lun0/part6
                        53G   422M    49G   1% /home
/dev/scsi/host0/bus0/target0/lun0/part8
                        23G -76.0Z    21G 101% /usr
/dev/scsi/host0/bus0/target0/lun0/part7
                        53G   3.0G    47G   6% /var

Thanks for any help

What filesystem is being run on that partition? It almost looks like some kind of REALLY weird filesystem corruption. Tried running fsck?

I read about this on another website, it was found to be a fault with the drive, see here: http://www.suramya.com/blog/ you should consider copying all data from it and do an RMA with the drive manufacturer (if the drive is still within the warranty period).

Thanks for the help. I've got this on an EXT3 filesystem with hardware RAID 5.

I have fixed the issue. Here's what I did:

booted from the Gentoo live install CD (It's a small iso to download and does everything I needed)

fsck -f /dev/sda8 (to check the partition even if it reports as being clean)

I then fixed all the errors that it found and rebooted. Problem solved
