Hi German,
This is what I’m running to redo an OSD as btrfs (not sure if this is the exact
error you’re getting):
DISK_LETTER=( a b c d e f g h i j k l )
i=0
for OSD_NUM in {12..23}; do
sudo /etc/init.d/ceph stop osd.${OSD_NUM}
sudo umount /var/lib/ceph/osd/ceph-${OSD_NUM}
sudo ceph auth del osd.${OSD_NUM}
sudo ceph osd crush remove osd.${OSD_NUM}
sudo ceph osd rm ${OSD_NUM}
# recreate again
sudo wipefs /dev/sd${DISK_LETTER[$i]}1
sudo dd if=/dev/zero of=/dev/sd${DISK_LETTER[$i]}1 bs=4k count=10000
sudo sgdisk --zap-all --clear -g /dev/sd${DISK_LETTER[$i]}
sudo kpartx -dug /dev/sd${DISK_LETTER[$i]}
sudo partprobe /dev/sd${DISK_LETTER[$i]}
sudo dd if=/dev/zero of=/dev/sd${DISK_LETTER[$i]} bs=4k count=10000
sudo ceph-disk zap /dev/sd${DISK_LETTER[$i]}
echo ""
echo "ceph-deploy --overwrite-conf disk prepare --fs-type btrfs
ceph2:sd${DISK_LETTER[$i]}"
echo ""
read -p "Press [Enter] key to continue next disk after running the above
command on ceph1"
i=$((i + 1))
done
There appears to be an issue with zap not wiping the partitions correctly.

Yours seems slightly different though. Curious, what size disk are you trying
to use?
Cheers,
Simon
