Hello, I'm following http://docs.ceph.com/docs/master/ceph-volume/lvm/prepare/#ceph-volume-lvm-prepare-bluestore to create new OSD's.
I took the latest branch from https://shaman.ceph.com/repos/ceph/luminous/ # ceph -v ceph version 12.2.1-851-g6d9f216 What I did, formatted the device. #sgdisk -Z /dev/sdv Creating new GPT entries. GPT data structures destroyed! You may now partition the disk using fdisk or other utilities. Getting below error while the creation of bluestore OSD's # ceph-volume lvm prepare --bluestore --data /dev/sdv Running command: sudo vgcreate --force --yes ceph-b2f1b9b9-eecc-4c17-8b92-cfa60b31c121 # use uuidgen to create an ID, use this for all ceph nodes in your cluster /dev/sdv stderr: Name contains invalid character, valid set includes: [a-zA-Z0-9.-_+]. New volume group name "ceph-b2f1b9b9-eecc-4c17-8b92-cfa60b31c121 # use uuidgen to create an ID, use this for all ceph nodes in your cluster" is invalid. Run `vgcreate --help' for more information. --> RuntimeError: command returned non-zero exit status: 3 # grep fsid /etc/ceph/ceph.conf fsid = b2f1b9b9-eecc-4c17-8b92-cfa60b31c121 My question 1. We have 68 disks per server so for all the 68 disks sharing same Volume group --> "ceph-b2f1b9b9-eecc-4c17-8b92-cfa60b31c121" ? 2. Why ceph-volume failed to create vg name with this name, even I manually tried to create, as it will ask for Physical volume as argument #vgcreate --force --yes "ceph-b2f1b9b9-eecc-4c17-8b92-cfa60b31c121" No command with matching syntax recognised. Run 'vgcreate --help' for more information. Correct command syntax is: vgcreate VG_new PV ... Please let me know the comments. Thanks Jayaram
