I have a database server that is running out of space. All my databases are being stored in a 80G /opt partition. Because I'm using LVM, wouldn't I be able to pop the HDDs (a h/w raid volume) in, add it to the LVM, and resize my ext3 /opt partition? Everything that I've been reading says this is possible, but I'm not sure. Has anyone done this and are there any pitfalls to watch out for? Is there a better way? I've thought about just rebuilding the server and restoring the databases from a backup on the new setup. Any suggestions on proper path would be appreciated. I'm running the current version of CentOS 5.
Hi,
This is perfectly possible with LVM. First add the HD (aka the HW RAID volume) to the OS. Then do a pvcreate on that disk so that LVM can use it. Then do a vgextend, this adds the disk to the volume group. A vgdisplay should then show that you have again free space in the volume group. Then you can do a lvextend and resize2fs as normal.
