Re: Ro,Rw permission Filesystem -linux

By default, Linux will change a filesystem to read-only mode if it detects errors on the disk. You may find disk error messages in the syslog (see the log files in /var/log) and/or in the "dmesg" command output.

My recommendation:
- take a backup of the /sed filesystem
- umount /sed
- fsck /dev/cciss/c0d1p3
- mount /sed

If the fsck command fails, the filesystem has been seriously damaged.

The device /dev/cciss/c0d1p3 is partition 3 on logical disk 1 of SmartArray controller 0. This is a hardware RAID controller: if you have the "hpacucli" tool installed, you can view the SmartArray configuration with this command:

hpacucli ctrl all show config detail

Re: Ro,Rw permission Filesystem -linux

If it got remounted read-only because of errors your filesystem is likely corrupted. You really should copy everything off or restore from backup. However, you may be able to umount, fsck until it stops returning errors, and remount.

Re: Ro,Rw permission Filesystem -linux

edit the /etc/fstab and add rw after the word defaults like below

/dev/cciss/c0d1p3 /sed ext3 defaults,rw 1 1


save the file and then execute the command

#mount -o remount /sed

then see the mount -v output
