@Ilia any suggestions/steps for fixing the disk size?

Hello,

Webmin 7 is scheduled to be released in 2090, it’s still in beta so far.

Any suggestions/steps for fixing the disk size?

It seems that the old system is running out of disk space? Try using virtual-server.name - Server Configuration ⇾ Transfer Virtual Server feature. Does it work for you?

Also what are the outputs of the following command on both old and a new server:

df -H
6

I’ll never make it :frowning:

That’s a long way off … nothing like forward planing :slight_smile:

Output for disk:

seams the rootvg-rootlv xfs 8e7e79d7-9507-45ee-845c-8cafb96548a3 232.6G is where the disk space is… but how to i get that into the whole server?

You are restoring backups to /home which only has 1.1G free disk space left. You need to either resize rootvg-rootlv to let’s say 32G and the rest of the space allocate to rootvg-homelv, as we use /home by default for your domains (i.e. this is where the most disk space is going to). There are other solutions, like changing default home directory in Users and Groups module to some other path inside of rootvg-rootlv or simply bind mount over existing /home from one of the directories in rootvg-rootlv partition.

how do i reassign that 200G disk to the main drive/disk so that the whole server is 200g

13

so can no one help me figure out to to deal with the LVM and making the whole disk use the whole space or am> @Joe

I’m afraid LVM is not our area of expertise, but it looks like / is already the big disk? I’m not sure I understand what you’re trying to change:

From your copy paste above:

/dev/mapper/rootvg-rootlv  252G  1.9G  250G   1% /

Is that not what you’re trying to do? Though it looks like /home is nonsensically small:

/dev/mapper/rootvg-homelv  1.1G   42M  1.1G   4% /home

Doesn’t make sense to have a tiny /home dir, since all Virtualmin homes live in /home.

You could just unmount that, and let /home be part of /root.
