Hi Christian, if i read a 1,5 GB file, which is not changing at all. Then i expect the agent to copy it one time from the cold pool to the cache pool. In fact its every time making a new copy. I can see that by increasing disc usage of the cache and the increasing object number. And the non existing improvement of speed. -- Mit freundlichen Gruessen / Best regards Oliver Dzombic IP-Interactive mailto:info@xxxxxxxxxxxxxxxxx Anschrift: IP Interactive UG ( haftungsbeschraenkt ) Zum Sonnenberg 1-3 63571 Gelnhausen HRB 93402 beim Amtsgericht Hanau Geschäftsführung: Oliver Dzombic Steuer Nr.: 35 236 3622 1 UST ID: DE274086107 Am 14.06.2016 um 02:48 schrieb Christian Balzer: > On Tue, 14 Jun 2016 02:38:27 +0200 Oliver Dzombic wrote: > >> Hi, >> >> if there isnt a problem, why are now 358 objects inside the cache pool >> running multiple times dd if=file of=/dev/zero while every full read of >> this 1.5 GB file produces around 8 objects inside the cache pool. >> > My response (now invisible, since your client did put the signature not at > the end) was specifically to your flush/evict assumptions. > >> Its the same file, read again and again. >> > At this point 358 4MB objects are still shy of the 1.5GB in your file. > > So if what Sam wrote is correct, the count will grow a bit more and then > stop around 380 objects. > >> But at no point its read from the cache. >> >> Its always read from the cold pool. >> > How are you determining that? > > Christian > _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
