Moving filesystems into LVM - query.
Hi Guys,

Looking for advice really this time, I have just completed building a server. As it was a fresh build and was just a standard RHEL 6.6 server which would run TSM I just went for partitioning up the disks as I built it.

The disks are 3 500Gb disks in a RAID5 configuration giving just under 1Tb of useable space. The build went smoothly and I built the filesystems as per the provided specification, but my european colleagues forgot to mention the fact that they wanted the disks under the control of LVM - I've found a lot of stuff about LVM and converting to it.

here is the output of a df;

Code:
[root@ekbtsmprod01 ~]# df -k

Does anyone have any thoughts on the best way forward with this - I have about 130Gb unalloacted on the RAD5 set.
