Meeting notes (thanks Serapheim):
-
OpenZFS Developer Summit (Matt)
-
Event pushed 1 week later than the initial date - to the beginning of
October
-
Talk Submission deadline extended by 2 weeks
-
If you have things you want to hear about feel free to ping Matt
and he can bug the right people
-
ZFS send compatibility for ZSTD (Allan)
-
Problem: Creating a stream that the receiving side can’t understand
(e.g. the receiving machine doesn’t know about ZSTD because it uses an
older ZFS version)
-
Multiple ways to go about it - there was common agreement that
whatever the solution it should probably follow the following principles:
-
The receiving side should be able to tell the user whether it
supports receiving the given stream, hopefully with a
friendly error message
-
The default behavior in general should be to use the latest and
most common thing but also give the option for the user to explicitly
downrev/configure it to their needs.
-
E.g. people rarely do plain `zfs send` without -c
-
The above principles are not expected to be enforced/implemented
for the ZSTD PR but they should guide the future direction of
dealing with
this issue. The ZSTD PR will proceed as discussed.
-
Activating feature flags on ‘zfs set’ instead of first block birth
(ZSTD) (Allan)
-
Problem: Activating a feature flag for a dataset, but not enabling it
(e.g. haven’t written any blocks yet), can cause panics when the
dataset is
opened by a ZFS version that doesn’t know about that feature.
-
This issue has been brought up in the past, the next steps would be
to have someone implement the fix.
-
What are the plans for OpenZFS release? (Alexander Motin)
-
There are no features officially holding the release.
-
Brian will create the 2.0 version branch mid-August and probably make
the release at some point before the end of the year.
-
The master branch will remain open for development during that time.
-
Any bug fixes applicable to the 2.0 branch will be “backported” from
master.
-
Forceful export - zpool export -F (Allan Jude)
-
Functionality: A pool’s suspension doesn’t cause ZFS operations to
hang for other pools (e.g. no holding the namespace lock. etc..). In
addition the suspended pool can be exported.
