Jitsi is really good, and getting better — we have been using it with my local User’s Group for the last couple of years. Only observation is to discover the maximum allowable number of guests in advance if this is not already known - we had a fairly generous allowance in BlueJeans accounts

[ceph-users] MDS host in OSD blacklist

Hi all, we have an octopus v15.2.17 cluster and observe that one of our MDS hosts showed up in the OSD blacklist: # ceph osd blacklist ls 192.168.32.87:6801/3841823949 2023-03-22T10:08:02.589698+0100 192.168.32.87:6800/3841823949 2023-03-22T10:08:02.589698+0100 I see an MDS restart that might

Hi Igor, i've offline compacted all the OSDs and reenabled the bluefs_buffered_io It didn't change anything and the commit and apply latencies are around 5-10 times higher than on our nautlus cluster. The pacific cluster got a 5 minute mean over all OSDs 2.2ms, while the nautilus cluster is

Hi, I found a way to preserve the rotational=1 flag for bcache-backed OSDs between reboots. Using a systemd drop-in for ceph-osd@.service, it now uses lsblk to look for a bcache device somewhere below the OSD, but sets rotational=1 in the uppermost LVM volume device mapper target only. This is

Hi Istvan, I currently make the move from centos7 to ubuntu18.04 (we want to jump directly from nautilus to pacific), When everything in the cluster got the same version, and the version is available on the new OS you can just reinstall the hosts with the new OS. With the mons, I remove the

Disabling the write cache and the bluefs_buffered_io did not change anything. What we see is that larger disks seem to be the leader in therms of slowness (we have 70% 2TB, 20% 4TB and 10% 8TB SSDs in the cluster), but removing some of the 8TB disks and replace them with 2TB (because it's by far
