Hi Stefan,
looks like bluefs allocator is unable to provide additional space for
bluefs log. The root cause might be lack of free space and/or high space
fragmentation.
Prior log lines and disk configuration (e.g. ceph-bluestore-tool
bluefs-bdev-sizes) might be helpful for further analysis.
ceph-bluestore-tool bluefs-bdev-sizes --path /var/lib/ceph/osd/ceph-2/
inferring bluefs devices from bluestore path
slot 1 /var/lib/ceph/osd/ceph-2//block
1 : size 0x18ffc00000 : own
0x[1400000~f3ec00000,f40100000~77ff00000,16c0100000~234300000,18f4500000~1900000,18f6000000~1300000,18fe000000~1c00000]
And here some log entries just before the assert that might be helpfull:
