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 :)
