read-only

So, this is it. Everything is working as usual except the disk is read only and dont want to change back.

^_^! thanks.

root@NODE02:/tmp# df .

root@NODE02:/tmp# mount -o rw,remount /dev/sda5
mount: cannot remount block device /dev/sda5 read-write, is write-protected

root@NODE02:/tmp# touch helll
touch: cannot touch `helll': Read-only file system

It's not multipath. It's nothing special. Just a server with ubuntu 9.10.

makes no sense for me, does it?

I guess I could chmod ... /dev/sdb1 but I was thinking of a more dynamic way (kind of like uid= and gid= options for vfat and such). >>> More
