That's correct - it's the removable flag that's causing the disks to be excluded. I actually just merged this PR last week: https://github.com/ceph/ceph/pull/49954 One of the changes it made was to enable removable (but not USB) devices, as there are vendors that report hot-swappable drives as removable. Patrick, it looks like this may resolve your issue as well. On Tue, Oct 24, 2023 at 5:57 AM Eugen Block <eblock@nde.ag> wrote:
Hi,
May be because they are hot-swappable hard drives.
yes, that's my assumption as well.

Hi Eugen,
Yes Eugen, all the devices /dev/sd[abc] have the removable flag set to 1. May be because they are hot-swappable hard drives.
I have contacted the commit author Zack Cerza and he asked me for some additional tests too this morning. I add him in copy to this mail.

Hi,
just to confirm, could you check that the disk which is *not* discovered by 16.2.11 has a "removable" flag?
cat /sys/block/sdX/removable
I could reproduce it as well on a test machine with a USB thumb drive (live distro) which is excluded in 16.2.11 but is shown in 16.2.10. Although I'm not a developer I tried to understand what changes were made in https://github.com/ceph/ceph/pull/46375/files#diff-330f9319b0fe352dff0486f66... and there's this line:
if get_file_contents(os.path.join(_sys_block_path, dev, 'removable')) == "1": continue
The thumb drive is removable, of course, apparently that is filtered here.
Regards, Eugen

I think you can try to roll back this part of the python code and wait for your good news :)
Not so easy 😕
