I also see on here that those commands are different then what is said on the CEPH page. http://docs.ceph.com/docs/master/rados/operations/placement-groups/#set-the-number-of-placement-groups and i also have to adjust the pgp_num as well.

Hello, Thanks for your help so far, i am still a little concerned because looking at the script that calculator generates it makes a new pool ceph osd pool create STORAGE 256 ceph osd pool set STORAGE size 3 while [ $(ceph -s | grep creating -c) -gt 0 ]; do echo -n .;sleep 1; done It doesnt...

Hello. Is it possible to have both standard Proxmox on for example 3 server with local disks and CEPH on 3 separate servers all in the same cluster? Would that cause any issues? or do they all have to be one or the other? or make 2 separate clusters? Thanks, Chris

I have now fixed it, i needed to zap and add via the command like for example ceph-disk zap /dev/sdb pveceph createosd /dev/sdb Then it should show in ceph osd stat Example root@INETC1084:~# ceph osd stat 6 osds: 6 up, 6 in

Hello, This is driving me insane. I have done exactly in the CEPH video and documentation but it does not work. When i create the OSD it makes it but doesnt show in the gui it just shows "default" I also made the pool and it shows as 0 available I think some documentation needs to be...

would this need to be done on node itself or on FreeNas where NFS is presented? it has been working fine and suddenly happened.
