Thanks Sergey! Do you know where I can find details on the repercussions of adjusting this value? Performance (read/writes), for once, not critical for us, data durability and disaster recovery is our focus. -Dan Get Outlook for iOS On Sun, Oct 21, 2018 at 8:37 AM -07

Awesome! Thanks Serian! Do you know where the 64KB comes from? Can that be tuned down for a cluster holding smaller objects? Get Outlook for iOS On Sat, Oct 20, 2018 at 10:49 PM -0700, "Serkan Çoban" mailto:cobanser...@gmail.com>> wrote: you have 24M objects, not 2.4

you have 24M objects, not 2.4M. Each object will eat 64KB of storage, so 24M objects uses 1.5TB storage. Add 3x replication to that, it is 4.5TB On Sat, Oct 20, 2018 at 11:47 PM Waterbly, Dan wrote: > > Hi Jakub, > > No, my setup seems to be the same as yours. Our system is mainly for > archivin

Hi Jakub, No, my setup seems to be the same as yours. Our system is mainly for archiving loads of data. This data has to be stored forever and allow reads, albeit seldom considering the number of objects we will store vs the number of objects that ever will be requested. It just really seems o

Hi Dan, Did you configure block.wal/block.db as separate devices/partition (osd_scenario: non-collocated or lvm for clusters installed using ceph-ansbile playbooks )? I run Ceph version 13.2.1 with non-collocated data.db and have the same situation - the sum of block.db partitions' size is displa

I get that, but isn’t 4TiB to track 2.45M objects excessive? These numbers seem very high to me. Get Outlook for iOS On Sat, Oct 20, 2018 at 10:27 AM -0700, "Serkan Çoban" mailto:cobanser...@gmail.com>> wrote: 4.65TiB includes size of wal and db partitions too. On Sat
