Comment 2 for bug 1830680

Hi Alex,

The step I took as 'juju add-disk ceph-osd devices='/dev/nvme6p1'. This step failed as there was no room in the bluestore to add another db & wal lvm.

This made the disk /dev/nvme6p1 unusable and to get is back to a state in where I could re-add it to the charm, I had to take the following actions:

    * lvremove -v /dev/ceph-b432de26-c075-4097-b699-1cf0f41f7402/osd-block-b432de26-c075-4097-b699-1cf0f41f7402
    * vgremove -v ceph-b432de26-c075-4097-b699-1cf0f41f7402
    * pvremove -v /dev/mapper/crypt-b432de26-c075-4097-b699-1cf0f41f7402
    * cryptsetup close /dev/mapper/crypt-b432de26-c075-4097-b699-1cf0f41f7402
    * partprobe /dev/nvme6n1

The last step was just to make sure that all was fine.

So I would be great if the addition of a disk fails due e.g. a problem with the bluestore, the whole creation of the lvm, vg, pv & crypto device would be reversed.
