Hi, Thank you for your reply. I don’t think the device names changed, but ceph seems to be confused about which device the OSD is on. It’s reporting that there are 2 OSDs on the same device although this is not true. ceph device ls-by-host <osd-node> | grep sdu ATA_HGST_HUH728080ALN600_VJH4GLUX sdu osd.665 ATA_HGST_HUH728080ALN600_VJH60MAX sdu osd.657 The osd.665 is actually on device sdm. Could this be the cause of the issue? Is there a way to correct it?
