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
