once after the
during booting linux(debian 3.0) found some corruption in root (/) partition. Then it corrected it; but problem here is root partition is getting mounted in readonly. Other partitions like /home /tmp /boot are normal (rw).
after doing
for the root partion it finds some errors in fs and then cleans it. Now if i do reboot then for some short time (may be 2-3 mins) root is mounted as rw. then it gets to its ro state.
Hi
I would like to write a shell script which should first check wheather the tape is placed in the tape drive .
if the tape is there
it should rewind it like mt -f /dev/rmt/0m rew
if the tape is missing from the tape drive
then send a mail saying that the tape is missing and exit.

how do you fsck the / filesystem? I know it does it automatically the next time I boot up following a switch on the wall shutdown but is there a flad somewhere that forces this on next boot up?
Thanks (2 Replies)
can somebody help me out in editing the /etc/fstab. I am on RHEL5 (Tikanga).
**The problem is that i have given a wrong LABEL in /etc/fstab for root volume and so after reboot, it is unable to resolve the wrong LABEL;
so, i have to edit the /etc/fstab :-(

fsck.jfs
fsck.jfs(8) JFS utility - file system check fsck.jfs(8)NAME
fsck.jfs - initiate replay of the JFS transaction log, and check and repair a JFS formatted device
SYNOPSIS
fsck.jfs [ -afnopvV ] device
DESCRIPTION
fsck.jfs is used to replay the JFS transaction log, check a JFS formatted device for errors, and fix any errors found.
device is the special file name corresponding to the actual device to be checked (e.g. /dev/hdb1).
fsck.jfs must be run as root.
WARNING
fsck.jfs should only be used to check an unmounted file system or a file system that is mounted READ ONLY. Using fsck.jfs to check a file
system mounted other than READ ONLY could seriously damage the file system!
OPTIONS
If no options are selected, the default is -p.
-a Autocheck mode - Replay the transaction log. Do not continue fsck processing unless the aggregate state is dirty or the log replay
failed. Functionally equivalent to -p. Autocheck mode is typically the default mode used when fsck.jfs is called at boot time.
-f Replay the transaction log and force checking even if the file system appears clean. Repair all problems automatically.
-n Open the file system read only. Do not replay the transaction log. Report errors, but do not repair them.
-o Omit the replay of the transaction log. This option should not be used unless as a last resort (i.e. the log has been severely
corrupted and replaying it causes further problems).
-p Automatically repair ("preen") the file system. Replay the transaction log. Do not continue fsck processing unless the aggregate
state is dirty or the log replay failed. Functionally equivalent to -a.
-v Verbose messaging - print details and debug statements to stdout.
-V Print version information and exit (regardless of any other chosen options).
EXAMPLES
Check the 3rd partition on the 2nd hard disk, print extended information to stdout, replay the transaction log, force complete fsck.jfs
checking, and give permission to repair all errors:
fsck.jfs -v -f /dev/hdb3
Check the 5th partition on the 1st hard disk, and report, but do not repair, any errors:
fsck.jfs -n /dev/hda5
EXIT CODE
The exit code returned by fsck.jfs represents one of the following conditions:
0 No errors
1 File system errors corrected and/or transaction log replayed successfully
2 File system errors corrected, system should be rebooted if file system was mounted
4 File system errors left uncorrected
8 Operational error
16 Usage or syntax error
128 Shared library error
