How to solve hard disk damage when Linux cropping system

In the system cropping, in order to reduce the waiting time, generally choose to hang the host and directly run the target system, but too frequent operation, often causes the hard disk can not be synchronized in time, causing the hard disk partition damage, resulting in the target system can not start normally. In this case, it would be too cumbersome to reformat the partition again.

This paper solves the problem by means of archive packing, and avoids the tedious repairing process effectively.

First, go to the root directory of the target system package compressed files to the specified location (assuming the host's/mnt/sysroot directory)

Find. | Cpio-h NEWC--quiet-o | gzip >/root/sysroot.2.gz

Second, uninstall the damaged partition

Fuser-km/mnt/sysroot

umount/mnt/sysroot/

Third, reformat and mount the partition

Mke2fs-j/dev/hda2

mount/dev/hda2/mnt/sysroot/

Iv. return to the root of the target system again, restore the files and perform the synchronization

cd/mnt/sysroot/

zcat/root/sysroot.2.gz | Cpio-id

Sync

Five, hang the host, open the target system of the virtual machine, the general will be able to run normally
