Your Linux server may not load after boot and requests fsck of the root filesystem. If this happens server filesystem goes into read-only mode.
- When prompted for language, and keyboard, provide the pertinent information for the system.
- Boot your server from CentOS ISO image and select rescue mode at the boot command prompt.
- When prompted to enable the network devices on the system, select: No
- If you are using Software RAID, first initialize the RAID array.
mdadm --assemble --scan
- Activate the volumes in order to scan them, If using LVM.
lvm vgchange -ay
1 logical volume(s) in volume group "VolGroup00" now active
- Run fsck on the device which has the root filesystem (ext3/ext4).
e2fsck -fvy /dev/mapper/vg device
e2fsck -fvy /dev/sd device
e2fsck -fvy /dev/md device
xfs_repair /dev/mapper/vg device
xfs_repair /dev/sd device
xfs_repair /dev/md device
- You may have to recreate the log if xfs_repair does not run. You may implement this by running xfs_repair -L
- Exit rescue mode and boot system normally.
