Expand a Hard Disk with Ubuntu LVM
On vCenter new disk 20G
Scan new disk
echo "- -
-" > /sys/class/scsi_host/host32/scan
#parted
When your system comes back
up, check on your new partition
So now let's pull it into
our LVM configuration. First we'll create the physical volume:
1/ Create
physical volume
Check disk
#pvdisplay
Now, extend our volume group
(mmvn)
into our new physical volume (/dev/sdb):
2/ Extend volume
group
The whole purpose of this
exercise is to expand the root filesystem, so let's find our main logical
volume:
#lvdisplay
Now, let's extend the
logical volume to all free space available:
3/
Extend logical volume
Or
lvextend -L +5G /dev/mmvn/root
4/
Next, extend the filesystem
# resize2fs /dev/mapper/mmvn-root
5/ Verify partition
