Hi Samuel, It can be a few things. A good place to start is to dump_mempools of one of those bloated OSDs: `ceph daemon osd.123 dump_mempools` Cheers, Dan -- Dan van der Ster CTO Clyso GmbH p: +49 89 215252722 | a: Vancouver, Canada w: https://clyso.com | e: dan.vanderster@clyso.com We are hiring: https://www.clyso.com/jobs/ On Wed, Jan 10, 2024 at 10:20 AM huxiaoyu@horebdata.cn < huxiaoyu@horebdata.cn> wrote:
Dear Ceph folks,
I am responsible for two Ceph clusters, running Nautilius 14.2.22 version, one with replication 3, and the other with EC 4+2. After around 400 days runing quietly and smoothly, recently the two clusters occured with similar problems: some of OSDs consume ca 18 GB while the memory target is setting at 2GB.
What could wrong in the background? Does it mean any slow OSD memory leak issues with 14.2.22 which i do not know yet?
I would be highly appreciated if some some provides any clues, ideas, comments ......
best regards,
Samuel
