[ceph-users] Re: classes crush rules new cluster

You could decompile the crushmap, add a dummy OSD (with a non-existing ID) with your new device class and add a rule, then compile it and inject. Here's an excerpt from a lab cluster with 4 OSDs (0..3), adding a fifth non-existing: device 4 osd.4 class test rule testrule { id 6

Hi Igor, Thank you for taking the time to explains the fragmentation issue. I had figured out the most part of it by reading the tracker and the PR but it's always clearer when you explain it. My question was more about why bluefs would still fail to allocate 4k chunks after being allowed to

[ceph-users] Snaptriming speed degrade with pg increase

Hi, When we scale the placement group on a pool located in a full nvme cluster, the snaptriming speed degrades a lot. Currently we are running with these values to not degrade client op and have some progress on snaptrimmin, but it is terrible. (octopus 15.2.17 on ubuntu 20.04) -osd_max_trimmi

Oh right, I always forget the reclassify command! It worked perfectly last time I used it. Thanks! Zitat von Anthony D'Atri : Apologies for the empty reply to this I seem to have sent. I blame my phone :o This process can be somewhat automated with crushtool’s reclassification directive

It looks like it is not possible to create crush rules when you don't have harddrives active in this class. I am testing with new squid and did not add ssd's yet, eventhough I added class like this. ceph osd crush class create ssd I can't execute this ceph osd crush rule create-replicated repl
