Title: Resize LVM Partition to max free space
Post by: HACKERSOFT2011 on February 17, 2021, 09:35:24 AM: Hi!

My smeserver main storage running on ESXI is now at around 90% full so I've decided to increase the virtual disk size to 700G.

My question is, how can I safely resize the LVM partition to fully use the available disk space in smeserver 9?

Code: [Select]

Post by: ReetP on February 17, 2021, 09:43:32 AM: Stacks of howto resize lvm around.

This was my first hit

https://www.rootusers.com/lvm-resize-how-to-increase-an-lvm-partition/

Note IIRC it is usually recommended to run "no lvm/no raid" on virtual machines.

Post by: HACKERSOFT2011 on February 18, 2021, 02:14:32 AM: I've already tried that prior to posting a question here but it does not see the remaining free space:

Code: [Select]

Free PE/Size = 0

But as you can see from below, the drive is now 834.3GB:

lvextend -l +100%FREE /dev/mapper/main-root lvresize -l +100%FREE /dev/mapper/main-root resize2fs /dev/main/root

and voila!

Title: Re: Resize LVM Partition to max free space
Post by: ReetP on February 19, 2021, 10:55:45 AM: Cool.

I'd take a look at v10 Beta 1 and if you are on a hypervisor lose the LVM. Think it save a bit of overhead, and resize issues ;-)

Remember it isn't like running real hardware where you need to add disks and increase the LVM.

You can just increase the VM size, resize the partition table and expand the file system. It is MUCH easier without LVMs (done it loads of times on my Prox servers)
Title: Re: Resize LVM Partition to max free space
Post by: ReetP on February 19, 2021, 11:44:37 AM: FYI - v10 defaults to a LVM install. You should be able to change that if you use the manual partitioner during install.

We are looking at ways to change/disable it during install like the old no raid/no lvm options, but no guarantees on that yet.
Title: Re: Resize LVM Partition to max free space
Post by: TerryF on February 19, 2021, 12:56:53 PM: Yep, when installing sme10 using the graphic installer you can delete the partition scheme that kickstart has created and created a custom one with no lvm, test vm running with this now, just a basic setup

Post by: TerryF on February 19, 2021, 12:59:48 PM: and there are those quicker on the gun than me

just redid mine, ext2 for /boot and ext4 for /

xfs_growfs /dev/mapper/main-root

That would only work on an xfs file system, but v9 is ext4.

CentOS7 defaults to xfs though there is some debate whether we use that or stick with ext4 for v10.

See the bug tracker for details.
