After following the Nagios XI - Resizing the VM Disk Size documentation step by step, we have come to a halt at resizing the logical volume (LV).

With the following command:

Code: Select all

# lvresize /dev/mapper/VolGroup00-LogVol00 /dev/sda2
The following error appears and the partition has not been resized.
Volume group "VolGroup00" not found
We are unable to the continuing steps to complete resize after this. Can you please assist?

Is this install from our provided CentOS VM or your own install? We can start with:

Code: Select all

ls -lv /dev/mapper/
df -h

Yes this is from your provided CentOS VM. I want to resize to the partition to 25GB

I have the following after starting the instructions again:

Code: Select all

[root@issmonitor ~]# lvresize /dev/mapper/volgroup00-logvol00 /dev/sda2
  Volume group "volgroup00" not found
[root@issmonitor ~]# ls -lv /dev/mapper/
total 0
lrwxrwxrwx 1 root root      7 Dec  1 17:33 VolGroup-lv_root -> ../dm-0
lrwxrwxrwx 1 root root      7 Dec  1 17:33 VolGroup-lv_swap -> ../dm-1

Replace all instances of "/dev/mapper/VolGroup00-LogVol00" with "/dev/mapper/VolGroup-lv_root" in the document's commands.

Code: Select all

lvresize /dev/mapper/VolGroup-lv_root /dev/sda2
resize2fs /dev/mapper/VolGroup-lv_root
