[jjc27017]

I want to create Ceph OSD but I can not chose the disk...

I only can chose the second option, but it can't work
I have seen the video in YouTube, it's not the same in this step

From our docs:

In order to select a disk in the GUI, to be more failsafe, the disk needs to have a GPT partition table. You can create this with gdisk /dev/sd(x). If there is no GPT, you cannot select the disk as DB/WAL.

Hi Alwin,
I just follow the instruction you mention in the last reply, I can create a osd and it succeed, but I can not see it in gui as I hope.

May you give some advise? It show I create successful. And I have already tried to reload it, but still can't see in gui.

the task log:

backup header from main header.

This shows the creation of the partitions of the OSD, but is the OSD started? What does 'ceph osd tree' tell you? All the ceph tools are still available for use on the PVE nodes.

Also check out this post and go through the docs, as they contain vital information on how to operate and troubleshoot Ceph.
