Hello,
I'm still fairly new to using LVM, and I need to do something on a live
server, so just need to be sure of what I'm doing...
Hardware:
3ware 9500S-8 Raid card with 8 Seagate 160GB hard drives
Ports 0 & 1 are mirrored, and contain:
Device Boot Start End Blocks Id System
/dev/sda1 1 100 803218+ 83 Linux
/dev/sda2 101 163 506047+ 82 Linux swap
/dev/sda3 164 2654 20008957+ 83 Linux
/dev/sda4 2655 19450 134913870 83 Linux
The other 6 are set up in a Raid 10, and contain:
Device Boot Start End Blocks Id System
/dev/sdb1 1 24900 200009218+ 8e Linux LVM
/dev/sdb2 24901 58352 268703190 8e Linux LVM
pvscan shows:
myhost # pvscan
/dev/cdrom: open failed: Read-only file system
Attempt to close device '/dev/cdrom' which is not open.
PV /dev/sdb1 VG vg2 lvm2 [190.74 GB / 0 free]
Total: 1 [190.74 GB] / in use: 1 [190.74 GB] / in no VG: 0 [0 ]
myhost #
lvscan shows:
myhost # lvscan
ACTIVE '/dev/vg2/home' [50.00 GB] inherit
ACTIVE '/dev/vg2/usr' [20.00 GB] inherit
ACTIVE '/dev/vg2/var' [120.74 GB] inherit
myhost #
So, /dev/sdb2 was being used for backups, but I was finally able to
convince the boss to let me get a QNAP NAS, so am using that for backups
now.
What I want to do is make the space from /dev/sdb2 available to my vg2
volume group, so I can extend my /var partition (it is filling up fast -
damn email packrats)....
Am I correct in that all I need to do is:
vgextend vg2 /dev/sdb2
then I can extend any of the logical volumes?
What I want to do is add all of /dev/sdb2 to the /var partition, so am I
correct taht to do this I would do:
lvextend -l %FREE /dev/vg2/var
(I think the %FREE is how I tell it to use all of it, right?)
then resize the filesystem (it is reiserfs):
umount /dev/vg2/var
resize_reiserfs /dev/vg2/var
mount -t reiserfs /dev/vg2/var /var
Thanks for any help and/or suggestions...

Charles
