Hi, Is there any information on this issue? Max number of OSDs per pool, or maxpool size (data) as opposed to cluster size? Thanks! -Chris -----Original Message----- From: Christopher Durham <[email protected]> To: [email protected] <[email protected]> Sent: Thu, Dec 15, 2022 5:36 pm Subject: max pool size (amount of data/number of OSDs)
Hi, There are various articles, case studies, etc about large ceph clusters, storing 10s of PiB,with CERN being the largest cluster as far as I know. Is there a largest pool capacity limit? In other words, while you may have a 30PiB cluster,is there a limit or recommendation as to max pool capacity. For example, in the 30PiB example,is there a limit or recommendation that says do not have a pool capacity of higher than 5iB, for 6pools in that cluster at a ttotal of 30PiB? I know this would be contingent upon a variety of things, including, but not limited to network throughput, individual serversize (disk size and number, memory, compute). I am specifically talking about s3./rgw storage. But is there a technical limit, or just a tested size, of a pool? Should I createdifferent pools when a given pool would otherwise reach a size capacity of Xor have N osds or PGs in it, when considering adding additional osds?
