Extending Datastore

[knippinski]

Hello,

we have installed PBS as a vm on PVE. The vm has a virtual disk for the Backup Storage. (40 GB as Directory Storage)

Now i want to expand the Storage. At the PVE side i increased the virtual disk. A moment later PBS shows the new disk size. (50GB)

But the Datastore shows 40GB. How can i tell the Datastore to use the additional 10 GB?

you need to resize the partition/../filesystem, e.g. as described in https://pve.proxmox.com/wiki/Resize_disks

@fabian,

The link you referenced uses parted to extend the file system. PBS iso install does not include parted and will not install with apt-get install parted. So what is the next step?

I am in a similar position with you, but I am using ZFS for my datastore.
So I have enabled autoexpand for the zfs pool and the pool automatically expanded to fill the new Virtual Disk:
zpool set autoexpand=on backup

You certainly should be able to install parted in a fresh debian, do you really mean that "apt update" and "apt install parted" is not installing it for you? What does "apt search ^parted" show?

Hello,

I have also installed PBS as vm on PVE with disks for datastore1 and datastore2. Currently also resized first disk and from PBS I run zpool set autoexpand=on datastore1 and disk was successfully resized. But on the tab ZFS datastore1 has original size. Could you please help me, how can I increase ZFS datastore?

Thank you
Daniel

Thank you @oversite for the reply. I guess I could have prefaced my post with my lack of experience in linux. Running apt update first did in fact allow install to run. I understand now why. I'm kicking myself for not thinking of that before I posted.

For others who may be struggling to extend a datastore....
(PBS installed in a PVE cluster. The pve virtual disk in PBS is /dev/sdb)

-resize disk in PVE
-verify resized disk in PBS -> administration -> storage/disks
-open PBS shell and run the following

parted /dev/sdb
(parted) print
Warning: Not all of the space available to /dev/sdb appears to be used, you can
fix the GPT to use all of the space (an extra ########### blocks) or continue
with the current setting?
Fix/Ignore? F
(parted) resizepart 1 Yes 100%
(parted) quit

(* I had to add "yes" to the resizepart line from the wiki tutorial)

resize2fs /dev/sdb1

(*this step can take some time)

-verify datastore extended

Thanks a lot for help. Datastore is expanded.

Seems that parted is no longer included in PBS
