Hello!

So, I have secondary HDD as part of my proxmox machine, this HDD was intended to be used for holding up backups but I was playing and testing proxmox and create some ZFS partition.

Now I want to format it and reconfigure that HDD to be used mainly for holding backup but when I try to wipe disk I get erorr tht wipefs failed, disk is busy, I did bunch of stuff, gone thru all proxmox config and managed to not use "hdd-zeus" anywhere but still problem. I tried to dd zeroes just to oerwrite stuff on it and still problem, now I get:

root@home-node-5500:~# mkfs.ext4 /dev/sda1
mke2fs 1.47.0 (5-Feb-2023)
/dev/sda1 is apparently in use by the system; will not make a filesystem here!
 
Sorry bbgeek!

Here are outputs!

Just one more thing, I can't restart that node so if there is solution without restart awesome, else, I will have to wait long time until restart.
 
You should plug the wipefs error into google and go through the suggestions available there, i.e.:
https://askubuntu.com/questions/926698/wipefs-device-or-resource-busy
https://askubuntu.com/questions/649052/error-wiping-newly-created-partition-dev-sdb1

It also sounds like you used this disk previously with PVE? What does /etc/pve/storage.cfg say? Any remnants of it there?
Restart PVE services: systemctl try-reload-or-restart pvedaemon pveproxy pvestatd pvescheduler pve-ha-lrm


If things are still not working, then post the actual commands you ran and errors your received.

Good luck

Thank you bbgeek!

I managed to wipe it with wipefs -af /dev/sda but still can't create via Proxmox GUI.


Code: 
root@home-node-5500:~# sudo umount /dev/sda*
umount: /dev/sda: not mounted.
umount: /dev/sda1: not mounted.

This is output of cat /etc/pve/storage.cfg

Code: 
root@home-node-5500:~# cat /etc/pve/storage.cfg
dir: local
        path /var/lib/vz
        content vztmpl,iso,backup
