Hi all, I’m trying to test/figure out how cephfs works and my goal is to mount specific pools on different KVM hosts : Ceph osd pool create qcow2 10000 Ceph osd dump | grep qcow2 -> Pool 9 Ceph mds add_data_pool 9 I want now a 900Gb quota for my pool : Ceph osd pool set-quota qcow2 max_bytes 120795955200 Ok, now how can I verify the size in Gb of my pool (not the replication size 1,2,3 etc) ? On my KVM host (client): Mount –t ceph ip1:6789,ip2:6789,ip3:6789:/ /disks/ OK Cephsfs /disks/ show_layout Layout.data_pool: 0 Etc… Cephfs /disks/ set_layout –p 9 –u 4194304 –c 1 –s 4194304 Umount /disks/ && mount /disks/ Cephsfs /disks/ show_layout Layout.data_pool: 9 Great my layout is now 9 so my qcow2 pool but : Df-h | grep disks, shows the entire cluster size not only 900Gb why ? is it normal ? or am I doing something wrong ? Thank you for your help J |
