[ceph-users] Re: [Ceph-users] Re: MDS failing under load with large cache sizes

Have you already tried to adjust the "mds_cache_memory_limit" and or "ceph tell mds.* cache drop"? I really wonder how the MDS copes with that with milions of CAPS.

I played with the cache size, yeah. I kind of need a large cache, otherwise everything is just slow and I'm constantly getting cache size warnings. ceph tell mds.* doesn't work when the FS is degraded.
