So I just extended the VG on my server. Basically, the local disk is 300GB. I initially created two partitions: sda1 is a primary partition, with ext4 assigned to /boot; sda2 is where 74G VG resides (vg is server hostname).
So I had an extra 225G left. I went ahead and created a third primary partition sda3, and after succesfuly creating a VG on sda3, I used lvextend to extend the size of my lv by 1GB.
So, here are the commands I ran after fdisk:
pvcreate /dev/sda3 vgextend hostname /dev/sda3 lvextend -L+1G /dev/hostname/home
For which I received the following output:
Extending logical volume home to 2.00 GiB Logical volume home successfully resized
However, the prompt has been stuck on the last message now for several hours. My attempts to perform an lvscan / or lvdisplay fail with the following error:
/var/lock/lvm/V_hostname: flock failed: Interrupted system call Can't get lock for hostname Skipping volume group hostname
So my question is, do you think my system actually succesfully performed the resize? Am I safe to reboot? Or should I wait around a little longer? This is LVM2, so I was under the assumption that I could perform these operations live while the lv is actively mounted. I know this depends on type of filesystem you're using, but I figured I was good since I am on ext4.
