OSD different sizes are used for different tasks. Such as cache. My concern is 4TB OSD, used as a storage pool. Place them engaged is not the same. /Dev/sdf1 4.0T 1.7T 2.4T 42% / var / lib / ceph / osd / ceph-4 /Dev/sdd1 4.0T 1.7T 2.4T 41% / var / lib / ceph / osd / ceph-2 /Dev/sdb1 4.0T 1.9T 2.2T 46% / var / lib / ceph / osd / ceph-0 /Dev/sde1 4.0T 2.1T 2.0T 51% / var / lib / ceph / osd / ceph-3 /Dev/sdc1 4.0T 1.8T 2.3T 45% / var / lib / ceph / osd / ceph-1 For example, on /dev/sdd1 42%, and /dev/sde1 51%. They are 1 pool. Maybe there is an option which can be used to fill evenly OSD? From: John Petrini [mailto:jpetrini@xxxxxxxxxxxx] You can reweight the OSD's either automatically based on utilization (ceph osd reweight-by-utilization) or by hand. See: It's probably not ideal to have OSD's of such different sizes on a node. ___ John Petrini NOC Systems Administrator // CoreDial, LLC // coredial.com //

I have set up the repository ceph and created several pools on the hdd 4TB. My problem lies in uneven filling hdd. root@ceph-node1:~# df -H Filesystem Size Used Avail Use% Mounted on /dev/sda1 236G 2.7G 221G 2% / none 4.1k 0 4.1k 0% /sys/fs/cgroup udev 30G 4.1k 30G 1% /dev tmpfs 6.0G 1.1M 6.0G 1% /run none 5.3M 0 5.3M 0% /run/lock none 30G 8.2k 30G 1% /run/shm none 105M 0 105M 0% /run/user /dev/sdf1 4.0T 1.7T 2.4T 42% /var/lib/ceph/osd/ceph-4 /dev/sdg1 395G 329G 66G 84% /var/lib/ceph/osd/ceph-5 /dev/sdi1 195G 152G 44G 78% /var/lib/ceph/osd/ceph-7 /dev/sdd1 4.0T 1.7T 2.4T 41% /var/lib/ceph/osd/ceph-2 /dev/sdh1 395G 330G 65G 84% /var/lib/ceph/osd/ceph-6 /dev/sdb1 4.0T 1.9T 2.2T 46% /var/lib/ceph/osd/ceph-0 /dev/sde1 4.0T 2.1T 2.0T 51% /var/lib/ceph/osd/ceph-3 /dev/sdc1 4.0T 1.8T 2.3T 45% /var/lib/ceph/osd/ceph-1 On the test machine, this leads to an overflow error CDM and further incorrect operation. How to make that all hdd filled equally?
