      Since I had posted, my disk usage had gone from 13G to 19G.

      Where are you checking this from, within pfsense or via the hypervisor/proxmox?

      From within pfsense. For example, below is the progression over a few hours today, but I do not see any change in the zvol reported on the host, proxmox.

        I believe this kind of zfs on zfs is not recommended

        Hello!

        It is not recommended.

        Comparing the output from df and du can be problematic, such as when you mount over the top of a folder that already has files in it, or a file has been deleted but is still open.

        You may need to try something like lsof or fstat to dig deeper.

          @serbus Thanks for the suggestion. Any recommendation incantations of fstat and lsof? I thought I might find unlinked files with lsof, but lsof +L1 / did not show any 0 in the NLINK column.

          Similarly, I am not sure what I am looking for with fstat...

            If I run five fsck from single user mode, as recommended in the docs, it shows no errors, even for the first run.

            Screenshot 2024-02-13 at 19.43.57.png

            But when I run fsck from the regular pfsense terminal, I have a lot of unreferenced files, though the free space is reported correctly because this is just after a fresh reboot.

            That is weird, right?

            fsck:

              Hello!

              This discussion and similar might have other leads you can follow.

                @serbus Thanks. Open, or zombie procresses/files is a likely candidate, though I cannot find any. In that link there are a couple of commands for linux that makes sense to me, but either do not turn up any results, or do not work on freebsd. Any idea what their equivalent might be?

                I am referring to are:

                lsof | grep -i deleted

                which returns nothing, and:

                [2.7.2-RELEASE][root@pfSense.spacelab]/: mount -o bind / /mnt
mount: /: mount option <bind> is unknown: Invalid argument
[2.7.2-RELEASE][root@pfSense.spacelab]/:

                which I think has an equivalent freebsd of:

                mount -t nullfs / /mnt

                Though once mounted, appear to be identical to /. No extra files in /mnt/var or anything...

                Was there any other avenue of exploration you saw that might help?

                Apart from the zombie processes/files, the other likely candidate in my mind is trim/discard/clean-up. What do you think about turning on trim for UFS in pfsense?

                  To add an unhelpful update. This problem was still occurring a few days ago, so I restarted as usual to start the ticking time bomb again.

                  I now have almost four days of uptime and available disk is in line with disk usage.

                  I swear I did not change anything or try to fix anything since this thread went quiet. In fact I have been convincing myself to go back to bare metal. Super weird and I don't trust it...

                    @sloopbun Did you ever get this resolved? I'm about to commit to a proxmox vm install myself.

                        @triks for anyone in the same boat, it ended up being NTOPNG that was filling the RAMDISK. Followed many posts but couldn't get it to save to SSD so removed it and that resolved the issue.
