Can you check the value of
kernel.pid_max. This may have to be increased for larger OSD counts, it may have some bearing? From: ceph-users [mailto:ceph-users-bounces@xxxxxxxxxxxxxx]
On Behalf Of John Hogenmiller (yt) I have 7 servers, each containing 60 x 6TB drives in jbod mode. When I first started, I only activated a couple drives on 3 nodes as Ceph OSDs. Yesterday, I went to expand to the remaining nodes as well as prepare and activate all the drives. ceph-disk prepare worked just fine. However, ceph-disk activate-all managed to only activate 33 drives and failed on the rest. This is consistent all 7 nodes (existing and newly installed). At the end of the day, I have 33 Ceph OSDs activated
per server and can't activate any more. I did have to bump up the pg_num and pgp_num on the pool in order to accommodate the drives that did activate. I don't know if having a low pg number during the mass influx of OSDs caused an issue or not within the pool.
I don't think so because I can only set the pg_num to a maximum value determined by the number of known OSDs. But maybe you have to expand slowly, increase pg's, expand osds, increase pgs in a slow fashion. I certainly have not seen anything to suggest a
magic "33/node limit", and I've seen references to servers with up to 72 Ceph OSDs on them. I then attempted to activate individual ceph osd's and got the same set of errors. I even wiped a drive, re-ran `ceph-disk prepare` and `ceph-disk activate` to have it fail in the same way. status: ``` root@ljb01:/home/ceph/rain-cluster# ceph status cluster 4ebe7995-6a33-42be-bd4d-20f51d02ae45 health HEALTH_OK monmap e5: 5 mons at {hail02-r01-06=172.29.4.153:6789/0,hail02-r01-08=172.29.4.155:6789/0,rain02-r01-01=172.29.4.148:6789/0,rain02-r01-03=172.29.4.150:6789/0,rain02-r01-04=172.29.4.151:6789/0} election epoch 12, quorum 0,1,2,3,4 rain02-r01-01,rain02-r01-03,rain02-r01-04,hail02-r01-06,hail02-r01-08 osdmap e1116: 420 osds: 232 up, 232 in flags sortbitwise pgmap v397198: 10872 pgs, 14 pools, 101 MB data, 8456 objects 38666 MB used, 1264 TB / 1264 TB avail 10872 active+clean ``` Here is what I get when I run ceph-disk prepare on a blank drive: ``` root@rain02-r01-01:/etc/ceph# ceph-disk prepare /dev/sdbh1 The operation has completed successfully.
