This is what things should look like:
sudo ceph-disk-prepare --fs-type xfs --zap-disk /dev/vdb
Caution: invalid backup GPT header, but valid main header; regenerating
backup header from main header.
Caution! After loading partitions, the CRC doesn't check out!
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.
****************************************************************************
GPT data structures destroyed! You may now partition the disk using fdisk or
other utilities.
