    @alexia is it media or the database that's causing you trouble? not caching remote media can save quite a bit of storage very easily

    @kopper honest to god I just checked with the du command what was taking up so much storage and got flashbanged with 51G /srv/iceshrimp and didn't bother checking any further than that

    but yeah good point we should probably turn that off

      @alexia owie (and that's why you don't opt for ext4 in 2025)

      @soop ext4 is solid still, we actually both wanted btrfs but didn't think of it at the time we set everything up.

        @alexia yeah that'll be media then. the database is harder to clean up but will show up under postgres (assuming you don't have both under the same directory)

          @alexia https://iceshrimp.dev/iceshrimp/Iceshrimp.NET/src/branch/dev/Iceshrimp.Backend/configuration.ini#L175-L179

          set these to 0 and send an API call to /api/iceshrimp/admin/drive/prune-expired-media (or in the dev versions there should be a button on the admin panel for it, unsure where though)

            @alexia if you just want optimal compression bcachefs is very efficent at that, but the current implementation is still a bit unstable and shaky performance wise so you shouldn't be using it yet, but it's something to note

              @soop btrfs with zstd:4 would be more than enough for us, and is considered much more stable.

              Just ask
              @niko what zstd:3 did to her server

                    @alexia are you using filesystem compression

                    @soop @alexia don't think compression would help a ton here tbh. media files already tend to be really compressed, and postgres also handles some compression (at least for text) on it's own

                      @soop No, unfortunately our VPS uses ext4 so there is no option for transparent filesystem compression

                      I know there is in-place conversion from ext4 to btrfs, but we'd rather not risk bricking
                      everything we host which includes both our fedi and our XMPP which are very important to us

                      Maybe with a future upgrade we'll remember to do btrfs, then use zstd compression there.

                      @alexia @soop btrfs-convert has failed and "ate my data" multiple times (i converted a disk image in place and also tried to make a new filesystem using the --rootdir flag and both times it failed)

                        @alexia @niko fyi once you do get set up with btrfs you'll want to disable the minecraft server\s builtin compression of region files

                            @soop @alexia looking into it a bit more, it seems like may actually help postgres in terms of disk space, but i'm unsure how much the perf regressions would be worth it

                              @kopper it is now slowly deleting 50G of data

                              and that would be most of our space reclaimed then
