@milan btrfs serves the files on my personal nas since... 8 years at lower, and has survived a drive slowly dying twice. And on my personal laptop it has been the rootfs since 2011.
Early problems have been lower performance, but that is an area where there has been constant improvement in the last few years and it is good now.
I can't vouch for raid5 or 6, but other than that it has done it's job without being annoying :)

hmm removed arc min size limit, raised arc max and ... hm i think that was what did the trick... didnt even drop caches or reboot

@milan Keep in Mind that you should have at least 2 GiB Base + 1 GiB/TiB-Storage.

@dk3jf hm maybe that increased (available) diskspace was a factor then

@milan zfs uses per default up to 50% of the system RAM.

@milan I've seen this before we have some VMs. And someone decided that 256MB should be enough for VMs . But when the VMs had more than ~200GB of ZFS Pool we ran into similar Problems.
