Growing filesystem using LVM
Hi,

I have a LUN presented to a Linux system and would like to ask if someone can advise if the logical volume /dev/mapper/VGOra-LVOra 12G 11G 659M 95% /usr/app/oracle can be extended. Is there any free space to allocate.... The LUN (25G) has been configured as follows:

Code:
 
LUN - ROOT... /dev/mapper/VGRoot-LVRoot = 6.6G
                   /dev/mapper/VGOra-LVOra = 12G
                   /dev/mapper/VGRoot-LVVar = 2.4G
                   /dev/mapper/VGRoot-LVTmp = 512mb
 
[root@jdcbpeltst6 ~]# df -h

I think you have free 16 GB on /dev/sdc


Code:
root@jdcbpeltst6 ~]# fdisk -l
.
.
.
Disk /dev/sdc: 16.1 GB, 16106127360 bytes
64 heads, 32 sectors/track, 15360 cylinders
Units = cylinders of 2048 * 512 = 1048576 bytes
.
.

you can configure a physical volume there and then add it to LVOra and VGOra.

Sun Fire thanks for the response. I will have a look at this disk and try as you suggest. Can I complete this without rebooting?

yes for LVM does notrequire a reboot

It can be done without a reboot by extending the logical volume, but I really recommend a full backup (tested) before you do this activitiy on a production machine
