Unable to remove and wipe old pve disk with lvm volume

[cjdnad]

I have an old disk from and old system that failed. I am trying to clean it up on my current new cluster.

It has LVM volume, BIOS and EFI

I have tried wipe, lvremove and so many variations of removal commands, but it just won't wipe.

Can anyone assist please?

Many thanks

Still no luck sadly

root@pveryzen:~# dd if=/dev/zero of=/dev/sdc bs=1024k

dd: error writing '/dev/sdc': No space left on device
244199+0 records in
244198+0 records out
256060514304 bytes (256 GB, 238 GiB) copied, 723.391 s, 354 MB/s

Does the script needs adjusting a little? Says no space left on device

Thanks!

No, that's correct as it's has written until the end of the disk and it's empty now. Look at "fdisk -l /dev/sdc", lsblk, pvdisplay etc

Also shows under LVM and LVM-Thin. It's being a bit stubborn no?
Current cluster is all zfs

Maybe have to reboot as this a "old data" in ram, seen somethink with nvme drives before too and after reboot the partitions cannot even more recognized then.
