Hello Group,
Currently we facing below issue.
*Issue : *
/scratch is on dasda1 device. We need mount sda device on /scratch so that
we can do porting work.
Steps taken to solve issue :
# umount -l /scratch
# fsck -y /scratch
fsck 1.39 (29-May-2006)
e2fsck 1.39 (29-May-2006)
fsck.ext3: Attempt to read block from filesystem resulted in short read
while trying to open /dev/sda1
Could this be a zero-length partition?
*cat /etc/fstab*
LABEL=/ / ext3
defaults,usrquota,grpquota 1 1
tmpfs /dev/shm tmpfs size=8045M 0
0
devpts /dev/pts devpts gid=5,mode=620 0 0
sysfs /sys sysfs defaults 0 0
proc /proc proc defaults 0 0
/dev/sda1 /scratch ext3 defaults 1 0
*We changed *
/dev/sda1 /scratch ext3 defaults 1 0
to
/dev/sda1 /scratch ext3 defaults 1 2
*So, that fsck run on reboot time and we rebooted system and after reboot
I was getting below messages.*
Checking all file systems.
-/sbin/fsck.ext3 (1) -- /- fsck.ext3 -a /dev/dasda1
/: clean, 177325/5412928 files, 1517520/5408976 blocks
-/sbin/fsck.ext3 (1) -- /scratch- fsck.ext3 -a /dev/sda1
fsck.ext3: No such file or directory while trying to open /dev/sda1
/dev/sda1:
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
-FAILED-
*** An error occurred during the file system check.
*** Dropping you to a shell; the system will reboot
*** when you leave the shell.
Give root password for maintenance
e2fsck -b 8193
Usage: e2fsck --panyrcdfvstDFSV- --b superblock- --B blocksize-
--I inode_buffer_blocks- --P process_inode_size-
--l|-L bad_blocks_file- --C fd- --j external_journal-
--E extended-options- device
Emergency help:
-p Automatic repair (no questions)
-n Make no changes to the filesystem
-y Assume "yes" to all questions
-c Check for bad blocks and add them to the badblock list
-f Force checking even if filesystem is marked clean
-v Be verbose
-b superblock Use alternative superblock
-B blocksize Force blocksize when looking for superblock
-j external_journal Set location of the external journal
-l bad_blocks_file Add to badblocks list
-L bad_blocks_file Set badblocks list
(Repair filesystem) 2 #
Any solution of this issue.
