Hey Paul. Admins typically don't want to set `pool.size` and prefer some auto discovery way... ;-) In the meantime (since several months now), we use btrfs on some 18 pool...

Hey. Actually, I'd have said the opposite, at least for the last year or so. The Fedora switch to btrfs seems to have brought quite some momentum into btrfs development,...

> Well, you're loosing 800 GiB because btrfs is reserving that amount for metadata, which isn't being used. No it's actually reserved for data, but the meta-data run full, and...

Anything new on this... ? This makes dCache pretty fragile, cause everytime domains start up, some may not be registered correctly Still happens with 7.2.10. ... and actually seems to...

That srm door was then also basically broken,... it gave endless of these: ``` Feb 22 20:43:16 lcg-lrz-srm dcache@srm_lcg-lrz-srm[28819]: 2022-02-22 20:43:16+01:00 (srm_lcg-lrz-srm) [] Internal server error: Request to [>gPlazma@local] timed...

I restarte ZK (one by one, so that at least 2 were always running),.. but still one pool fell out: ``` Feb 23 01:59:15 lcg-lrz-dc27 dcache@pool_lcg-lrz-dc27_1[32611]: 2022-02-23 01:59:15+01:00 (c-core1-AAXYoMmquGg-AAXYoMmtb7g) [core1,7.2.10,CORE]...

If you mean the one from https://github.com/dCache/dcache/issues/5326#issuecomment-1048149959 ... than that's unfortunately already gone, and I had cleared the files after completely restarting everything. It contains now just: ``` 022-02-23 13:47:06,266...

That's output from a zookeeper log, from one of the domains that was affected with this earlier today: ``` # cat pool_lcg-lrz-dc24_6.log 2022-02-23 13:47:13,090 [CURATOR: STARTED] connection state now CONNECTED...

Is there anything else I can do for debugging? I mean it's rather annoying to reproduce the problem (since that means breaking transfers) - but it's also pretty easy (simply...
