Errors in /var/log/messages:
kernel: Current sda: sense key Recovered Error kernel: Additional sense: Failure prediction threshold exceeded kernel: EXT3-fs error (device sda9) in ext3_setattr: Journal has aborted kernel: EXT3-fs error (device sda9) in start_transaction: Journal has aborted
Fix with (requires reboot + can be slow):
fsck.ext3 -f -y /dev/sda9
To identify that name /dev/sda9 I used:
fdisk -l e2label /dev/sda9
Following this, force a full fsck to double check everything with:
touch /forcefsck reboot
The /forcefsck file is removed automatically post reboot.
If that doesn’t fix the problem – and maybe even if it does, for safety – replace the hard disk.
