Hi, I have 52 OSD’s in my cluster, all with the same disk size and same weight. When I perform a: ceph osd df The disk with the least available space: 863G The disk with the most available space: 1055G I expect the available space or the usage on the disks to be the same, since they have the same weight, but there is a difference of almost 200GB. Due to this, the MAX AVAIL in ceph df is lower than expected (the MAX AVAIL is based on the disk with the least available space). - How can I balance the disk usage over the disks, so the usage / available space on each disk is more or less the same? - What will happen if I hit the MAX AVAIL, while most of the disks still have space? Thanks! Sinan |
