Description

Hello,

I have a new small freshly installed Octopus 16.2.5 cluster on ARM with Samsung SSD 7.6TB 2.5 SATA PM883 disk (MZ7LH7T6HMLA-000) and the "orch device ls" command of ceph reports that this device has HDD type although it should be detected as SDD as you can see below:

$ ceph orch device ls
Hostname  Path      Type  Serial          Size   Health   Ident  Fault  Available  
ceph1g    /dev/sda  hdd   REMOVEDSERIAL  7681G  Unknown  N/A    N/A    No

As workaround I manually changed the class type but I guess it should have been detected as SDD when adding that specific OSD device.

Would you be able to run `cephadm ceph-volume inventory` on your node with the SSD device ? and compare the `rotates` field in the output with the ceph orch device ls output.

Just to be sure if the issue is coming from ceph-volume or the orchestrator itself.

Stumbled upon the same issue,

three identical VMware VMs attached to all-flash-storage. Bootstrapped Pacific 16.2.5 once and all devices were correctly identified as SSD. Reverted to snapshot and installed a second time, then one device was detected as HDD.

$ ceph orch device ls

ceph-1a /dev/sdb ssd 107G Unknown N/A N/A No
ceph-1b /dev/sdb ssd 107G Unknown N/A N/A No
ceph-1c /dev/sdb hdd 107G Unknown N/A N/A No
