Check your physical devices.

nirmit · 06-11-2008, 03:16 AM

i have checked the drive...
no problem with it.

U can try this -- remount the filesystem with rw permissions...
for ex. # mount -o remount rw /dev/sda1
Then clean tmp and again run makewhatis..

i have tried to mount /
bt it gives me an error like:-

[root@vasdb ~]# mount -o remount -t ext3 rw /
mount: block device rw is write-protected, mounting read-only

What is your partitioning scheme?

Does dmesg produce any output (other than I/O error)?

nirmit · 06-11-2008, 06:37 AM

this is the o/p of the dmesg:-

EXT3-fs error (device cciss/c0d0p8) in start_transaction: Journal has aborted

now,please tell me what should i do?...

Try rebooting your machine and see if it works. If not ... then log into single user mode using command "init 1"

and run fsck command as fsck -y.

Thanks,

That should be
mount <device> -t ext3 -o remount,rw

You don't have a device (which may be OK for the remount option) and the options aren't separated by comma's. So (rw) was taken as a device instead of an option.
