I can report the same just after a few month of working with ZFS. I now get this error message I try to do an apt upgrade:
ERROR couldn't save system state: Minimum free space to take a snapshot and preserve ZFS performance is 20%. I am using ZFS on Ubuntu 21.10 on a private notebook that I use _occasionally_ meaning maximum once per week without a lot of data intensive stuff going there. I agree with other comments that this ZFS default behaviour gives a bad impression on an otherwise great filesystem. The idea of snapshots is a good one but should have much saner defaults that also take into account on how much space they take. With that experience I would never enable ZFS with Ubuntu on a production relevant box. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1895943 Title: zsys automatic snapshots just eat up all drive space and never get cleaned up To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zsys/+bug/1895943/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
