Linux LVM Logical Volume error recovery case __linux

Use LVM to establish a logical volume as/dev/mapper/test-test.

Due to an abnormal shutdown, a logical volume error was made and cannot be mounted.

So check the logical volume and prompt:

# fsck.ext3-f/dev/mapper/test-test
E2fsck 1.38 (30-jun-2005)
Fsck.ext3:Attempt to read blocks from filesystem resulted into short read while trying to open/dev/mapper/test-test
Could this is a zero-length partition?

Then, look at the information for this logical volume:

# mkfs.ext3-n/dev/mapper/test-test
MKE2FS 1.38 (30-jun-2005)
FileSystem label=
OS Type:linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
6553600 inodes, 13107200 blocks
655360 blocks (5.00%) reserved for the Super user
The Data block=0
Block groups
32768 blocks per group, 32768 fragments per group
16384 inodes per group
Superblock backups stored on blocks:
32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,
4096000, 7962624, 11239424

Then, try it and fix it with a spare super block:

# Fsck.ext3-b 163840/dev/mapper/test-test
E2fsck 1.38 (30-jun-2005)
Fsck.ext3:Attempt to read blocks from filesystem resulted into short read while trying to open/dev/mapper/test-test
Could this is a zero-length partition?

The result is still an error. Then try restarting the LVM service and performing

/ETC/INIT.D/LVM stop

/ETC/INIT.D/LVM start

And then execute:

# Fsck.ext3-b 163840/dev/mapper/test-test
E2fsck 1.38 (30-jun-2005)
EXT3 recovery flag is clear, but journal has data.
Recovery flag not set in Backup Superblock, so running journal anyway.

/dev/mapper/test-test: * * * * FILE SYSTEM was MODIFIED * * * * *
/dev/mapper/test-test:31/6553600 files (3.2% non-contiguous), 1823265/13107200 blocks

Perform/etc/init.d/checkfs.sh start, or you can check and repair the file system.
