Ceph cannot specify wal/ db

[maomaocake]

Hi, Im adding OSDs to my ceph clusterusing the command below, however it say that there are incompatible values which is not what is specified here https://docs.ceph.com/en/latest/rados/configuration/bluestore-config-ref/ . Am i understanding something wrong?

im using ceph version 18.2.4.

ceph-volume lvm create --bluestore --data ceph-block-7/block-7 --block.db ceph-db-3/db-7 --block.wal ceph-db-3/wal-7 --dmcrypt
--> Incompatible flags were found, some values may get ignored
--> Cannot use None (None) with --bluestore (bluestore)
--> Incompatible flags were found, some values may get ignored
--> Cannot use --bluestore (bluestore) with --block.db (bluestore)
--> Incompatible flags were found, some values may get ignored
--> Cannot use --block.db (bluestore) with --block.wal (bluestore)

edit: The disks show up fine in the ceph dashboard and is working as expected.So im not sure is this a problem

The same problem after upgrade from 17 to 18. I have 5 nodes and at 4 is great, only at one I got the error.

root@ceph02:~# ceph-volume lvm prepare --bluestore --data vg-pd$DATA_DISK_PD/data-lvl --block.db vg-$NVME_DISK/db-lvl
--> Incompatible flags were found, some values may get ignored
--> Cannot use None (None) with --bluestore (bluestore)
--> Incompatible flags were found, some values may get ignored
--> Cannot use --bluestore (bluestore) with --block.db (bluestore)
-->  AttributeError: 'NoneType' object has no attribute 'startswith'

I checked the packages versions and they are the same on all nodes.

Any ideas? Reboot, reinstall ceph-volume, and check md5sum of the python script done.

I resolved it. By mistake, i have a vg with "-" at the end.
