/var partition turned to read only

hi,

i am having trouble on my linux machine running in centos 5. my machine restarted and after booting my /var partition changes to read-only.

i tried to create a file on /var but i get error.

Code:

[root@server ~]# touch /var/test
touch: cannot touch `/var/test': Read-only file system

i command mount to see my file system.

Code:

[root@server ~]# mount
/dev/hda2 on / type ext3 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/hda6 on /home type ext3 (rw)
/dev/hda5 on /var type ext3 (ro)
/dev/hda1 on /boot type ext3 (rw)
tmpfs on /dev/shm type tmpfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)

i did a fsck on /dev/hda5 and it seems to be ok.

Code:

[root@server ~]# fsck /dev/hda5
fsck 1.39 (29-May-2006)
e2fsck 1.39 (29-May-2006)
/dev/hda5 is mounted.  

WARNING!!!  Running e2fsck on a mounted filesystem may cause
SEVERE filesystem damage.

Do you really want to continue (y/n)? yes

/var: clean, 2130/12812288 files, 4801684/12799780 blocks

i also try to remount.

Code:

[root@server ~]# mount -o remount /var
mount: block device /dev/hda5 is write-protected, mounting read-only

is there is any way to make my /var to RW?

thanks in advance.

Code:

sudo chmod -R 777 /var

That isn't going to do anything if it's mounted read-only.

Code:

mount -o remount,rw /var

Change your /etc/fstab file so that /var gets mounted as rw instead of ro.

Extremely unlikely fstab has ro - logs wouldn't work. More likely it has remount-ro for /var.
The mount command needs to be run as root, but really it probably needs a fsck.
