Hello, thanks for reply.
I tryed to add à LVM disk but:
And same in "Directory" tab ^^
You can do many things but it depends on what you like to do.
And also do you need the data redundancy because the service must stay online.
And the most important thing is how your backup is working.
When you know these things we can help you.
I guess you should read a bit of the basic.

I don't need RAID. I need ext4 filesystem.
Backups are created by proxmox every day.
Thank you for your links, I read everything and I learned a lot !
Then I would recommend you to reinstall with the Proxmox VE iso [1] install if this is possible.
But this way you will lose all your data on the system.

after deleting the directory and the disk, there was a record in the "disk" - "directory" - the path and device. How to clear from not a valid entry?

Hello,
I have same problem. 2 disks was running before, today I check the storage can not use, but the VMs on these storage are still working.
lsblk --ascii :
ls /dev/nvme*n1 | xargs -n 1 sgdisk -p
ls /dev/sdc | xargs -n 1 sgdisk -p
How can I fix this problem?
thanks
Hello, all!
I have a problem with a disk that was previously used as a data storage for VM images. I destroyed all data with the parted command. Now I want to use this disk as Ceph OSD.
I see what the problem is. lsblk shows the content that was on disk. But I do not understand what needs to be done now to clear this output. And how do I use the disk as Ceph OSD now?

Physical disconnection and connection of the disk helped. The disk was identified under a different letter (not sda) and became available for further manipulations.
