[ceph-users] LARGE_OMAP_OBJECTS 1 large omap objects

Hi, I'm trying to understand the "LARGE_OMAP_OBJECTS 1 large omap objects" warning for out cephfs metadata pool. It seems that pg 5.26 has a large omap object with > 200k keys [WRN] : Large omap object found. Object: 5:654134d2:::mds0_openfiles.0:head PG: 5.4b2c82a6 (5.26) Key count: 286083 Size (bytes): 14043228 I guess this object is related to the open files on the (cephfs mds0_openfiles.0). But what exactly does it tell me? Is the number of keys the number of currently open files? If yes, this is not matching the sum of open files over all clients obtained with lsof (which is less than 1000). So how can I get rid of this? (Reboot the clients?) Thanks for your help Dietmar -- _________________________________________ D i e t m a r R i e d e r, Mag.Dr. Innsbruck Medical University Biocenter - Institute of Bioinformatics Innrain 80, 6020 Innsbruck Email: dietmar.rieder(a)i-med.ac.at Web: http://www.icbi.at
