参考

cephタブが見えるようになるまで

各proxmoxで実行

pveceph install
pveceph init --network 192.168.30.0/24
# /etc/pve/ceph.conf が作成される。
pveceph createmon

ここまで成功。

OSDの作成

以下コマンドラインでもできるし、WebUIのceph->Disks->Create: OSDでも出来る。

WebUIのほうが推奨。

osdの作成

# pveceph createosd /dev/sdc
create OSD on /dev/sdc (xfs)

Caution: invalid backup GPT header, but valid main header; regenerating
backup header from main header.

Warning! Main and backup partition tables differ! Use the 'c' and 'e' options
on the recovery & transformation menu to examine the two tables.

Warning! One or more CRCs don't match. You should repair the disk!

****************************************************************************
Caution: Found protective or hybrid MBR and corrupt GPT. Using GPT, but disk
verification and recovery are STRONGLY recommended.

Warning: The kernel is still using the old partition table.
The new table will be used at the next reboot.
