This is the first time that I used the installer instead of setting up a minimal debian. Now I was doing this to get a native ZFS installation in place but I'm already regretting that I started this.
My system was using vast amounts of RAM. To conquer this I upgraded from 16 to 32GB RAM but the system kept rebooting. I placed a limit to it and also changed some parameters on the ZFS pool (I use LZ4 compression)
zfs set primarycache=metadata rpool/swap
zfs set secondarycache=metadata rpool/swap
zfs set compression=off rpool/swap
zfs set sync=disabled rpool/swap
zfs set checksum=on rpool/swap
Swapiness doesn't seem to help and is not set at the moment. Set it to 10 as suggested in the wiki.
I also had to set a higher timeout on the snapshots. Which worked before the ZFS install without any issue.
I'm really fed up with this since the random reboots leave no traces in any log file... My backups fail (since they trigger the random reboots) and I'm really starting to fear to loose data (and yes I have a copy but that doesn't mean this should be possible).
Any suggestions excluding starting all over again and go back to ext4 on LVM?
