I'm new to NAS, OVM, Docker and so on. I wanted to experiment with a home server and installed OVM 5 on a 4 GB USB thumb drive. I was trying to follow some tutorials about installing some stuff with docker/portainer, but I can't manage to complete anyone due to space issues. I checked and my OMV drive is already full, little more than 1 MB free space (not sure if this is bare OVM or if I manage to already install things that I can't recall now) . Should I start again from an 8 GB drive or is there a way to install Calibre, Midnight Commander or other software bypassing the lack of space in my system drive? I'm using an internal HDD and 2 external HDD (1 TB each) to hold data. Thanks!
8GB ought to do it for now. I run on a 16GB SSD, it's now half full, but has been in use for five years.
Flash media is really cheap. The price difference between 8, 16, and 32 is going to be miniscule at best. 8 is minimum, I would personally go 16 or 32. That said, if your system is set up properly, 8 should be fine. I've got a lot of dockers, etc. going on my system and I'm using 2.8gigs on my system partition (that is not counting the swap space).
I have just checked my installation drive and I realized that it's actually 8 GB. Below is the information I got from parted. It seems that I have almost 4 GB in swap. Is that alright? RAM memory on that server is 4 GB, not sure if they should match. I think I didn't change any parameter during installation, those seem to be the default values.
Number Start End Size File system Name Flags
1 1049kB 538MB 537MB fat32 boot, esp
2 538MB 4316MB 3778MB ext4
3 4316MB 8010MB 3694MB linux-swap(v1)
Inside OVM panel, aAt Storage/File Systems, the system partition reads: Total 3.40 GiB, Available 1.19 MiB, Used 3.20 GiB. And I think I haven't installed anything (maybe vim and ncdu). Shouldn't I have more space available for other installations?
Can I just downsize the swap to enlarge the system partition? How do I do that?
