Renaming a FILESYSTEM


Hi...ALL

I M new to LINUX

During installation of Linux (RHEL 5) i have created a filesystem Named "/oracle"....now i want to rename the same to "/oracledbase"

(The content of the "/oracle" file system is zero and the file system is... ext3)

Please help me

You just need to create the directory /oracledbase and mount the relevant filesystem (i.e. partition, NFS share, etc) there.

The name in fstab must be the same as the new name you gave the directory (mount point). (You have "oracledbase" and "oradbase")

But: If it is now booting into maintenance mode, there is something else wrong. Can you post the complete content of /etc/fstab, and also the results of "fdisk -l" (ell, not one---and run this as root)

Since you renamed the mount point, the entry in /etc/fstab fails, dropping you into the maintenance console if you don't have the noauto option.

Have you tried commenting out the changed file system line in fstab? Does it boot OK then? If it does then we know that line was the cause of the boot problem. If it does not then there is some other reason for the boot problem. Please post your fstab here.

Now you have "oracle" and "oradata" in fstab, but not either of the other two names you mentioned. Again, the directory (mount point) must have the same name as the fstab entry.

Have you tried catkin's suggestion?

You could also try bypassing the LABEL method and mount the partitions by actual device names----e.g.:
Code:
/dev/hdd1 / ext3 defaults 1 1
Make a backup of the fstab file before making any more changes.

It might be helpful to post the output from this command, too
Code:
/bin/ls -l /dev/disk/by-label/

THANK YOU VERY MUCH..everybody..I have solved my problem....using following Steps.

1) Make a directory in root named "oracledbsae" given "chmod 777" permission.
2) unmount /oracle filesystem
3) changed the /etc/fstab entries...from

LABEL=/oracle /oracle ext3 defaults 1 2

TO

LABEL=/oracledbase /oracledbae ext3 defaults 1 2

4) changed the LABEL using the following command "e2label /dev/hdd5 oracledbase"

5) Reboot the system

Glad you got it working. 777 permissions are more open than necessary and so less secure. That may not matter in your situation.
