I have installed NS 8 with Debian 12 as substructure on my Proxmox. Initially only as a leader node with Samba AD on it. Nothing else. Now I had the idea to add another machine with NS8 (also Debian 12 as substructure) as a node and install Nextcloud and Collabora on it. I have set up everything, added LE certificates and have access to the NC instance and also to the Collabora admin page. However, if I now want to open a document (whether a Word or Excel file), the message shown in the picture appears and the file does not open immediately. After what feels like 20 seconds, the file does open and can be edited without any problems. In one of my earlier attempts with NS 8 and Rocky 9.2 as a substructure with only one Leader Node, this worked without any problems with the same settings.
KVM + ZFS + NS8 + NextCloud + NextCloud Office… on this hardware seems a bit too much.
SSD can help to reduce latency due to disk access and transfer rate, however… All this slices are not that thin to chew.
I know that seems counter-intuitive, but I’d try to lower the cores on the NS8 guest, allowing Proxmox to have more grunt to manage the underlying processes.
I’d won’t go on three cores, however into the history some processor had (AMD…).
Unfortunately, I’m not deep enough into the subject to be able to answer the question. But the fact is that the problems I described earlier have disappeared from the face of the earth since I switched to Rocky Linux.
I have already done this by installing three additional nodes and integrating them as workers. Nextcloud and Collabora on one, Webtop and Mailserver on the second and Mattermost on the third. Nothing really worked. Now I have installed everything on a Leader Node (Rocky) and everything is running fine.
May I suggest to put into docs this experience. This is the wording I’d use.
If you’re considering to install in any virtual environment NethServer 8, some users experienced better performances using Rocky Linux instead of Debian 12.
Also, the pre-made VM image is Rocky Linux based.
Just a simple… feel free to elaborate, modify, make it compliant with the current wording and style.
After a further test with a new virtual machine (OS Rocky) and Samba-AD as account provider, I can confirm that all applications that previously did not work under Debian 12 are running flawlessly and at a good speed. At the moment these are Collabora, Mailserver, Mattermost, Nextcloud and Webtop. Opening documents with Collabora works well. I installed Webtop normally from the software center and not with the command that @stephdl posted here.
