Consolidating LVM volumes..

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Hi,

Something I haven't done before is reduce the number of volumes on my server.. Here is my current disk setup..

[root@server1 /]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/VolGroup00-RootVol00
                       15G  1.5G   13G  11% /
/dev/md0              190M   42M  139M  24% /boot
/dev/mapper/VolGroup00-DataVol00
                       39G   16G   22G  42% /data
none                  157M     0  157M   0% /dev/shm
/dev/mapper/VolGroup00-HomeVol00
                       77G   58G   15G  80% /home
/dev/mapper/VolGroup00-VarVol00
                       16G  382M   15G   3% /var

Rather than try and reduce the size of the VarVol00 volume to make more unallocated space which I have heard is a little dangerous.. I would like to get rid of the VarVol00 and have the /var directory on the RootVol00 volume.. Then I can allocate some of the free space to HomeVol00 which is filling up..

So how do I do this?

Do I simply copy /var to /var2 and then edit the /etc/fstab file to remove the line that mounts VarVol00??

Then at what point and how do I rename /var2 to /var to get it all working as normal again?

Should this all be done in "single" mode?

As you can see I am really not sure about this procedure so any help or step by step instructions for be great..

Thanks..
