Occasionally hard drives encounter continuity errors, even on Linux. Recently I had a disk which I tried running every manner and combination of FSCK commands and various other repair tools. After giving up and returning to the issue, the following solved my drive troubles:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | [root@nuuk /]# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 74.5G 0 disk ├─sda1 8:1 0 1G 0 part /boot └─sda2 8:2 0 73.5G 0 part ├─centos-root 253:0 0 44.4G 0 lvm / ├─centos-swap 253:1 0 7.5G 0 lvm └─centos-home 253:2 0 21.7G 0 lvm /home sdb 8:16 0 298.1G 0 disk └─sdb1 8:17 0 298.1G 0 part /media/usb_drive2 sdc 8:32 0 1.8T 0 disk └─sdc1 8:33 0 1.8T 0 part /media/usb_drive1 sdd 8:48 0 1.8T 0 disk └─sdd1 8:49 0 1.8T 0 part /media/usb_drive3 |
sdd1 was giving me issues:
1 2 | umount /dev/sdd1 fsck /dev/sdd1 -y -C |
To check for bad blocks as well (very time consuming):
1 2 | umount /dev/sdd1 fsck /dev/sdd1 -y -C -c |
For XFS Partitions with Superblock issues:
1 2 3 | xfs_repair /dev/device xfs_repair -n /dev/device xfs_repair -L /dev/device ##Potentially destructive use as last resort |
