Public bug reported:
Updates of my system stopped, because the boot partition has been
cluttered up with snapshots. Note that remedy in the error message is
completely wrong! See the annex!
>From a programming point of view zsys and zsysctl do work and are an
achievement. However from an architectural point of view, they hamper
the elegance of zfs. They keep creating snapshots and filling up the
partitions without any simple way to control the increase in clutter and
size. I now have over 25 snapshots of my system and all snapshots,
except say a few are completely useless.
The commands of zsysctl use a terminology different from zfs for the
same objects and the commands have no added value compared to those of
zfs itself. Documentation of the commands are missing and it is
completely unclear, which functions will be implemented at which moment
in the future. Functions are missing and one of the obvious missing
functions is related to new users created after installation.
For my 2 main systems (desktop and laptop), both running 20.04, I have purged
zsys and zsysctl and I will rely on plain zfs and its grub related adaptions.
For the VM I will delete the snapshots and pray for a solution for people with
less experience than me.
Please if you are serious about zfs:
- create a good written architecture specification
- create a project plan, about which functions will be implemented when.
- collect enough programming capacity to implement those changes according to
that plan.
I have the feeling, that the current "team" is completely understaffed
and lacks the OpenZFS, ZOL and Ubuntu management support, they deserve.
Why should you take my warning serious? I have 40 years of experience in
software development; have designed an OS; run a software department of
more than 100 persons for more than a decade and finished my last 10
working years (2001-2010) as chief architect of Eurocontrol (Say the
European FAA, serving ~30 independent countries).
