Expand storage size on Univention Nextcloud 14

Hi Everyone,

As (I can imagine) everyone runs into the issue of running out of space on their Nextcloud. Was looking to expand it. I cannot find accurate guide how to properly expand the storage. Found a guide for version 13 (https://www.pandatech.co/2018/05/increase-nextcloud-13-storage-extend-zfs/) but on Univention it is not ZFS. What would be the way to expand the drive size? I am looking to expand it by additional 400GB which is added addtitional drive on VMware (other methods are welcome too).
Any help ir greatly appreciated.

Details of the storage:

Expanding disk space for Nextcloud
#2

Hi,

I am unsure as I have not tested any dockerized version. But would this article help?

/CV

Thanks Christian. As it is dockerized version it might not work. Will give it a shot anyways :wink:

Anyone else can throw some advice? :slight_smile:

Just a few thoughts why I would not see a problem following the mentioned article:

The topic of the article is “How To Extend Disk Space on Next-/Owncloud Appliance”. Nextcloud has always been dockerized on UCS, ownCloud is dockerized for a couple of years.
In addition the output of “df -h” at the end is showing typical mounts for docker apps.

What could be done to add more flexibiltiy for future expansions would be not just to increase the “root” volume group. The last advice in the article is

It would be much easier to do if Own-/ Nextcloud had mounted /var on a separate disk!

Moving “/var/” out of “/” after the installation needs some experience because lots of services will have to be stopped and the existing data has to be moved while retaining all ownerships and permissions.
I’d think that the attempt to create a separate LVM-partition for “/var/lib/univention-appcenter/apps/nextcloud/” or the data directory below could also be worth to look at and should hopefully not break future changes of the integration.
Again: this is optional and needs some knowledge.

hth,
Dirk
