Hi,
just wondering if 'ceph-volume lvm zap --destroy /dev/sdc' would help
here. From your previous output you didn't specify the --destroy flag.
Which cephadm version is installed on the host? Did you also upgrade
the OS when moving to Pacific? (Sorry if I missed that.

Hi all,
still stuck with this problem.
I've deployed octopus and all my HDD have been setup as osd. Fine.
I've upgraded to pacific and 2 osd have failed. They have been
automatically removed and upgrade finishes. Cluster Health is
finaly OK, no data loss.
But now I cannot re-add these osd with pacific (I had previous
troubles on these old HDDs, lost one osd in octopus and was able to
reset and re-add it).
I've tried manually to add the first osd on the node where it is
located, following
https://docs.ceph.com/en/pacific/rados/operations/bluestore-migration/ (not
sure it's the best idea...) but it fails too. This node was the one
used for deploying the cluster.

Any idea of what is wrong ?

I'm still trying to understand what can be wrong or how to debug
this situation where Ceph cannot see the devices.
The device :dev/sdc exists:
[root@mostha1 ~]# cephadm shell lsmcli ldl
Inferring fsid 250f9864-0142-11ee-8e5f-00266cf8869c

/dev/sdc | 50024e920387fa2c | PATA/SATA | S2B5J90ZA02494 | Good
But I cannot do anything with it:
[root@mostha1 ~]# cephadm shell ceph orch device zap

Error EINVAL: Device path '/dev/sdc' not found on host
'mostha1.legi.grenoble-inp.fr'
Since I moved from octopus to Pacific.
