#242489 — ceph storage

Hello

I am installing ceph storage. I have 3 monitors, 3 OSD servers. I am
using the link below for installation. (*) The error I get is as
follows. I couldn't run "fdisk" on the OSD server.

What could cause the problem?

I could be wrong, but isn't ceph-deploy deprecated?

Regarding your specific error, it'd be worth diving in the python code
and try to put some debug prints at some relevant steps. Python3 is
trying to decode a string, which can't work, as strings in python3 are
already decoded (versus "bytestring" which are not).

Cheers,

I did not use native package. I'm still testing.

Yes it looks like that. I think I will use native packages.
