Re: [ceph-users] Testing a node by fio - strange results to me

Hi Ahmed, no, I mean the normal linux cache on the OSD-nodes. If an file was read, they stay in the cache (how long depends on memory and activity). The next reading will be very fast. But you can have further caching (IMHO the client caches with cephfs too). Udo On 23.01.2017 07:07, Ahmed K

Hi, I don't use mds, but I thinks it's the same like with rdb - the readed data are cached on the OSD-nodes. The 4MB-chunks of the 3G-file fit completly in the cache, the other not. Udo On 18.01.2017 07:50, Ahmed Khuraidah wrote: > Hello community, > > I need your help to understand a little
