Hi Igor, you're right indeed, the db volume is 100G in size for the hdd osds. Knowing this, the actual raw use is 783G - 7x100G = 83G which is pretty close to the sum of the files in the HDD pools times the pool size which is roughly 25x3=75G. Thanks a lot for your explanation of this tiny but highly confusing detail. Best Georg Igor Fedotov wrote: > Hi Georg, > > I suspect your db device size is around 100GiB size?
