Hello list! We have a containerized Pacific (16.2.5) Cluster running CentOS 8.4 and after a few weeks the OSDs start to use swap quite a lot despite free memory. The host has 196 GB of memory and 24 OSDs. "OSD Memory Target" is set to 6 GB. $ cat /proc/meminfo MemTotal: 196426616 kB MemFree: 11675608 kB MemAvailable: 48940232 kB Buffers: 46757632 kB Cached: 653216 kB .... $ smem -k Command Swap USS PSS RSS ceph /usr/bin/ceph-osd -n osd.22 1.7G 3.7G 3.7G 3.7G ceph /usr/bin/ceph-osd -n osd.10 853.4M 4.6G 4.6G 4.6G ceph /usr/bin/ceph-osd -n osd.12 793.6M 4.6G 4.6G 4.6G ceph /usr/bin/ceph-osd -n osd.92 561.3M 4.7G 4.7G 4.7G ceph /usr/bin/ceph-osd -n osd.14 647.2M 4.9G 4.9G 4.9G ceph /usr/bin/ceph-osd -n osd.15 567.8M 5.0G 5.0G 5.0G .... Is that a known behavior, an bug or configuration problem? On two hosts I turned of swap and the OSDs a running happily now for more the 6 weeks.
