I need to resize /dev/mapper/VolGroup-lv_home disk size was increased but the partition I still small Not sure if it can be resized without damage, I assume the home partition is on /dev/xvda2 , see below.
Looks like xvda2 is hosting the single PV constituting "VolGroup", and /home is a logical volume in that group. Please provide the output of the commands "cat /proc/partitions", "pvdisplay", and "vgdisplay".
The server is remote from my location, so don’t assume I can do this unless I’m local to the server.
Hmm, why would that make a difference?
ideas, comments apprecitaed
The safest way is probably to create an additional partition (type LVM) on the free space on xvda, pvcreate(8) an additional PV on it, and vgextend(8) the volume group with that. You can then lvextend(8) the lv_home volume and finally use resize2fs(8) to grow the filesystem on it.
I'm less sure that moving the end of xvda2 and using pvresize(8) would work.
