Support For multiple SSD's

[Dr4goonD3mon]

Hi, I've been using steam OS for a while and found an annoying issue that has to be fixed soon, I have 3 drives in my system 2 ssd m.2 and one sata after installing steam OS the system detects the three both on game-mode and on kde plasma, the 3 drives are these: a 512gb Samsung ssd, a Fanxiang S880 NVMe SSD 1TB and a 240gb sata ssd the 512gb is where the OS is installed, on game-mode i can format the 240gb drive and set it to work, but the 1tb drive can't be formatted on game-mode and when i go to kde to format it it works but in the moment i enter game-mode the drive appears as empty and ready to format but after trying to format it says that is an error, the farthest that i go is formatting on kde and then going to game-mode, there is detected but in the moment i restart the system it goes to where i was, using gemini i get to use a script to set the drive as an SD card but every time the system updates it goes to be detected as empty and i have to enter the command from ssh again, please add support for multiple ssd drives on steam OS, many people are making steam machines on they own, and will going to have this issue too

Your post is difficult to read. Some formatting and less run on sentences would go a long way.

Hi, I've been using steam OS for a while and found an annoying issue that has to be fixed soon. I have 3 drives in my system, 2 ssd m.2 and one sata. After installing steam OS the system detects the three both on game-mode and on kde plasma.

The 3 drives are these:
- Samsung ssd 512gb
- Fanxiang S880 NVMe SSD 1TB
- sata ssd 240gb

The 512gb is where the OS is installed. On game-mode i can format the 240gb drive and set it to work. The 1tb drive can't be formatted on game-mode. When i go to kde to format it, it works. In the moment i enter game-mode the drive appears as empty and ready to format. After trying to format it says that is an error. The farthest that i go is formatting on kde. Then going to game-mode, there is detected but the moment I restart the system it goes to where i was.

Using gemini i get to use a script to set the drive as an SD card but every time the system updates it goes to be detected as empty and i have to enter the command from ssh again, please add support for multiple ssd drives on steam OS, many people are making steam machines on they own, and will going to have this issue too.

Not sure why you are trying to have an NVME drive show up as a SD card. Even though I do not run SteamOS, let me attempt to help.

AI response for what to do to a drive post-installation
--------
Managing Additional Drives Post-Installation
Once SteamOS is installed on the primary drive, you can add secondary NVMe drives for game libraries:

- Boot into Desktop Mode.
-Use the Disks utility (KDE Parition Manager - which I believe you have used) to format the new drive (e.g., to ext4 or btrfs).
- Set up automount options in Disks to ensure the drive mounts at boot. (This is what I do not know if you are doing. If you are just mounting the disk and do not setup auto mount, then the mount will not be persistent across reboots.
- Open Steam, go to Settings > Storage, and click Add Drive to include the new NVMe in your library.

After you have followed these steps. Check to see if the disk is in your /etc/fstab file. You can run 'cat /etc/fstab' from a terminal to see if the disk will mount on boot. The file should look something like:

UUID=44c67007-1fab-4543-bb6f-c1480bfd2e17 /home btrfs exec 0 0
UUID=a9495fdb-e137-408c-8199-5349183fabbc /mnt/games ext4 nofail,users,exec 0 0
UUID=007195eb-2548-4de8-9e26-7e9dbcdf5635 /mnt/games2 ext4 nofail,users,exec 0 0
UUID=c4b49f0d-2fce-4ca9-8683-57dee43fe542 /mnt/wine ext4 nofail,users,exec 0 0

Right click the partition, not the drive, the partition of the drive and click properties. Make sure that the UUID is in the /etc/fstab file. If it is not, then you will need to disable readonly and edit the file manually.

- to disable readonly: sudo steamos-readonly disable
- to edit the fstab file: sudo nano /etc/fstab
- to enable readonly: sudo steamos-readonly enable

If you do not know how to edit the fstab file correctly, there are tons of information on the internet on how to accomplish this. You could also check out the lines from my fstab file above. You need a directory to mount it to. You need the UUID. You need to make sure that 'users' have access. Gemini can also help walk you through editing the drive on SteamOS.

Cheers!

I have multiple drives and they work 100%. I use SteamOS 3.9
