  1. After (instantly) disabling quotas the issue is remedied. Even though I have 214 subvolumes it seems ridiculous to me that quotas would use enough RAM to cripple a system. Is this a (upstream) bug? When i read "Performance issues" I think slow IO speed, not crippling RAM usage.
  2. Okay, it has something to do with 'btrfs-cleaner'. After mounting my RAID kmalloc-128 starts growing. Steps I've taken were install, define root password & user name+password, `apt-get update && apt-get upgrade`, reboot and mount my RAID. `umount` also hangs. (Probably because btrfs-cleaner is running.) # ps -o pid,user,%mem,command ax | sort -b -k3 -r PID USER %MEM COMMAND 1381 root 0.4 /usr/bin/python3 /usr/share/unattended-upgrades/unattended-upgrade-shutdown --wait-for-signal 777 root 0.4 /usr/bin/python3 /usr/bin/networkd-dispatcher --run-startup-triggers 784 root 0.3 /usr/sbin/NetworkManager --no-daemon [...] # top -b -n 1 top - 13:28:22 up 5 min, 3 users, load average: 3.83, 2.02, 0.84 Tasks: 179 total, 3 running, 176 sleeping, 0 stopped, 0 zombie %Cpu(s): 0.7 us, 20.9 sy, 0.0 ni, 78.4 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st MiB Mem : 3799.0 total, 1598.0 free, 1755.0 used, 446.0 buff/cache MiB Swap: 1899.5 total, 1899.5 free, 0.0 used. 1884.1 avail Mem PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 2540 root 20 0 0 0 0 R 66.7 0.0 2:32.56 btrfs-cleaner 2705 root 20 0 8948 3028 2664 R 9.5 0.1 0:00.09 top 2688 root 20 0 7188 3360 2604 S 4.8 0.1 0:01.15 htop 1 root 20 0 165100 9372 7052 S 0.0 0.2 0:04.59 systemd 2 root 20 0 0 0 0 S 0.0 0.0 0:00.03 kthreadd [...] `armbianmonitor -u`: http://ix.io/2REF
  3. Sadly I seem to have broken my install because the RAM got filled while I was using `armbian-config` to revert a kernel version. With regards to top/ps; As i mentioned nothing pops up with a large usage. I've got a fresh install booting now, I can see if the problem reproduces. (And at what step.)
  4. I'm having an aggressive memory leak issue I can't place: Within 5 minutes the 4GB are full. htop and top don't show a massive program growing unbouded. `df` doesn't show a tmpfs that is too large. Only `slabtop` is imforative: OBJS ACTIVE USE OBJ SIZE SLABS OBJ/SLAB CACHE SIZE NAME 26638624 26638624 99% 0.12K 832457 32 3329828K kmalloc-128 So `kmalloc-128` is growing without bounds. As I understand it kmalloc is a collection of smaller memory allocations? I've tried using a previous kernel version (5.10.16 and 5.10.12) but nada. I've disabled docker, and that along with omv were the only services running. Any suggestions would be great!

  6. A 2.5" variation for either a SSD based NAS; or a low power NAS with 2.5" HDD's. Of course the current design could be used for 2.5" drives, but a more compact design would be nice.
