Hi cephers, We have some ceph clusters use cephfs in production(mount with kernel cephfs), but several of clients often keep a lot of caps（millions） unreleased. I know this is due to the client's inability to complete the cache release, errors might have been encountered, but no logs.
client kernel version is 3.10.0-957.21.3.el7.x86_64 ceph version is mostly v12.2.8 ceph status shows: x clients failing to respond to cache pressure client kernel debug shows: # cat /sys/kernel/debug/ceph/a00cc99c-f9f9-4dd9-9281-43cd12310e41.client11291811/caps total 23801585 avail 1074 used 23800511 reserved 0 min 1024 mds config: [mds] mds_max_caps_per_client = 10485760 # 50G mds_cache_memory_limit = 53687091200 I want to know if some ceph configurations can solve this problem ？ Any suggestions? Thanks.
