MDS_CACHE_OVERSIZED warning

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi.

I have a cluster that has been running for close to 2 years now - pretty
much with the same setting, but over the past day I'm seeing this warning.

(and the cache seem to keep growing) - Can I figure out which clients is
accumulating the inodes?

Ceph 12.2.8 - is it ok just to "bump" the memory to say 128GB - any
negative sideeffects?

jk@ceph-mon1:~$ sudo ceph health detail
HEALTH_WARN 1 MDSs report oversized cache; 3 clients failing to respond to
cache pressure
MDS_CACHE_OVERSIZED 1 MDSs report oversized cache
    mdsceph-mds1(mds.0): MDS cache is too large (91GB/32GB); 34400070
inodes in use by clients, 3293 stray files


Thanks - Jesper
