I incorrectly named a filesystem mount on my server.  What would be the best way to rename the mount system?

Edit /etc/fstab and either reboot or unmount and remount it

I do that and I get the following:

# mount -a
mount: special device LABEL=/mount/point does not exist
Copy your current /etc/fstab in please

Sorry - neglected to consider the LABL syntax. You've got to relable the partition. Use e2label and then remount

"e2label /dev/sda1" << iterate through your drives until you find /oracle/archivelog
"e2label /dev/sda1 /<newlabel>"
edit /etc/fstab to reference the new label
"mount -o remount,rw /<newlabel>"
Note that you can just do "fdisk -l" to find the /dev partitions

After I have done this:

# mount -o remount,rw /oracle/archivelog
mount: no such partition found

Is there something else I ca look at?

Thanks for your help...
Lets say the old label is /oracle/OLDarchive and the new label is /oracle/NEWarchive

You identified the /dev partition associated with /oracale/OLDarchive - call it /dev/sda1
You confirmed that was correct eith "e2label /dev/sda1"
You renamed it with "e2label /dev/sda1 /oracle/NEWarchive"
You renamed any /oracle/OLDarchive entries in /etc/fstab to /oracle/NEWarchive
You remounted /oracle/NEWarchive << if that doesn't work then remount /oracle/OLDarchive

Can you confirm this?

I'm still having problems getting this:

mount -o remount,rw /oracle/archivelog
mount: no such partition found

I restarted the server, the OS would not boot because it could not verify the /oracle/archivelog
while it was doing the fsck.
I had to enter a record on the /etc/mtab as well.  But still no luck.  Any help would be great.
This one is on us!

Thanks very much!  You were right, the LABLE was /oracle/archivel - I had
/oracle/archivelog in the fstab.
