OpenSUSE Leap 15.2 released

[Posted July 2, 2020 by corbet]

The openSUSE Leap 15.2 release is now available; see the announcement for a long list of new features. "In general, software packages in the distribution grew by the hundreds. Data fusion, Machine Learning and AI aren't all that is new in openSUSE Leap 15.2; a Real-Time Kernel for managing the timing of microprocessors to ensure time-critical events are processed as efficiently as possible is available in this release."

Ran an update yesterday during a video conference (on another machine!) on a heavily customized audio production machine. Went very smoothly, everything seems to work. Only downside is that the machine seemingly locked up for 10 minutes today - on closer look, it turned out that brtfs was doing some large-scale housekeeping... now back to normal.
Grew increasingly tired of 15.1 as it was ageing. I "downgraded" to it from Tumbleweed after the latter had exploded in my face once too often, but since I'm building much of my business software from source, it's nice to have a really recent system.

All in all, a very happy SUSE user here since 1998, although I hope they will be accelerating their release schedule again after the re-syncing with SLES. Kudos to all contributors!

I find the snapshot stability checks very informative to see when it makes sense to update or to what date (with tumbleweed the command):

Otherwise it feels almost like running Factory.

It'd be useful to see top at the time it was happening, but there aren't any "housekeeping" items per se other than btrfs-cleaner thread. It helps with deleting snapshots, but only gets busy if there are many snapshots (hundreds) or a very large diff between snapshots.

I suspect it might be some hold over btrfs-maintenance tools that openSUSE used to ship. These were basically just systemd service units and timers, which weren't part of upstream's btrfs-progs. These units did activate btrfs commands found in btrfs-progs. I think just scrub and balance. I'd have guessed they'd disable these following upgrades by now, but - dunno.

Scrub and balance operations us IO priority idle class. I don't know how effective those are, and it could depend on the IO scheduler. I think in a cgroup2 world, these would get put automatically into their own systemd scope so they are subject to CPU and IO isolation.

Could also be i/o tools aren't that well debugged, especially throttling ...

I'm on the raid mailing list, and while I haven't seen any recently, there've been a fair few threads where people have wondered why raid fixing or syncing or other stuff either runs excessively slow, or won't throttle and swamps the machine.

Cheers,
Wol

Not listed in their blog post, but I'm quite happy that 15.2 also backports WireGuard to their 5.3 kernel, so SUSE users now have out-of-the-box wg support.

Bought myself a new notebook on Friday and installed openSUSE Leap 15.2 from scratch. Absolutely smooth, everything works out of the box (which didn't do on this model a few wears ago with the 4.12.x kernel). Touchpad, Trackpoint, Audio, Sleep-Modes, Function keys, everything is working fine. Great work, congratulations to the openSUSE team.

I upgraded two days ago and things have been running well for the most part (except for a regression in Remmina which I still have to report).

What's really nice is that I can finally play with Podman and rootless containers. That wasn't possible on Leap 15.1 since the older kernel was missing some bits for that to work.
