Hello everyone, I have a Raspberry Pi 4B with 2GBs of RAM. I am trying to run all the *arr stack via docker containers(5 or 6 containers) but this causes my Raspberry Pi to lag very much. I could not use any of the stack's web interface or SSH to the pi during the lag and to fix it I had to reset the pi.
I think it is because I have little RAM but it might also be the power supply because I sometimes get messages for undervoltage.
What do you think is happening and how could I fix it? Do I need to buy a more powerful device?
Just checked on my pi4 with 4GB of ram that has been running beautifully as a NAS with 2x10TB USB drives mirrored, *arr suite, and Jellyfin for a couple of years, only 250mb of RAM free. I’m glad I splurged and got the 4gb model.
While not untrue, it’s not entirely accurate. My entire arr stack runs on a 3b+ with just a gig of ram, with some still left over. It all depends on what, and how you run it
Agree! I had arr stack + nextcloud on rpi4 4GB and it was using bit less than 3GB after restart, but after some time it would hit 4GB and start using SWAP and I would have issue just like OP. Solved that by moving server to DIY PC with 8 GB, but then I added many more services and had to upgrade to 16 GB. Sitting at 4+GB free RAM all the time while using 40+ services
I saw that it uses about 1,3 GB of memory. This means another 700MB remain. Because of this, I don't think the cause is the memory. Also, I forgot to mention that I am also running qbittorrent for downloading, gluetun for VPN, and jellyfin and jellyseerr.
Begin with listing what exactly you’re trying to run. I am running this myself, on hardware that’s worse than yours. You have to make choices more carefully
