Hi Ceph Community One of my customer has an issue with the MDS cluster. Ceph cluster is deployed with cephadm and is in version 16.2.7. As soon as MDS is switched from Active-Standby to Active-Active-Standby, MDS daemon starts to consume a lot of RAM. After some time it consumes 48GB RAM, and container engine kills it. Same thing happens then on the second node which is killed after some time as well, and the situation repeats again. When the MDS cluster is switched back to Active-Backup MDS configuration the situation stabilizes. mds_cache_memory_limit is set to 4294967296, which is the default value. No health warning about high cache consumption is generated. Is that known behavior, and can it be solved by some reconfiguration? Can someone give us a hint on what to check, debug or tune? Thank you. Kamil Madac _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
