Increase size of PBS Datastore Directory

[Noah0302]

Edit: fixed it in my latest comment!

----------

Hello guys,


I'm running PBS 2.2-6 on my TrueNAS SCALE as a VM.
I started out with a 6TB Volume for my PBS Storage and a 32GB Volume for my PBS Boot drive.


The Storage started to fill up, so i increased the 6TB Volume to 11TB.
After a Reboot PBS did recognize the change from 6 to 11TB:


The directory did stay the same size though:



I could not find anywhere how to increase the Datastore to the full size of the Disk, only with ZFS wich I don't use within PBS, so I would greatly appreciate any help!



Thanks for reading.

After extending the disk size, you usually need to extend the filesystem as well. Did you do that? With resize2fs you should be able to extend the filesystem. Be aware that while this is relatively harmless, such operations always carry a slight chance of some mishap happening, so if you have very critical data on that disk it might be wise to have backups ready. That being said, I have often done online resizing and never had an issue - just a disclaimer.

Hello, thanks for the reply.

No, I have not yet done that. I also have not done that at all so far, I'm pretty new to Linux filesystems.
How would I go about doing this? I want to extend the PBS-Storage02 to the full size of the disk (from 6TB to 11TB)



If I understand correctly, I would need to run:
1. gparted
2. resize2fs /dev/vdb1



I created a manual Snapshot of the Storage disk in TrueNAS, in case anything goes wrong, I should be able to rollback.

Can you post the output of fdisk -l /dev/vdb ?

 

[Noah0302]

Can you post the output of fdisk -l /dev/vdb ?

Sure:


and in code form:

Okay, thanks.

So yes, you need to first increase the size of your partition and then the size of the filesystem afterwards. As you already said you can do this with gparted (GUI) or you can also use fdisk in the CLI if you are comfortable with that. After you have resized your partition, you have to run resize2fs /dev/vdb1 to also extend the filesystem. So yes, your approach is correct.

Thank you very much!

I'll try it out and see if it works

It worked!


I used the following commands, in case someone needs it in the future:

sgdisk -e /dev/vdb

sgdisk -d 1 /dev/vdb sgdisk -N 1 /dev/vdb

apt install parted partprobe /dev/vdb

resize2fs /dev/vdb1

Thank you for posting that write-up. This was exactly what I was looking for!

Thx a lot, I've used your approach to resize my volume

Thanks, heaps! Still working 2 years later.
