i ran the sgdisk you mentioned above, but the disks still are not available for a zpool creation: root@proxmox3:~# zpool create -f -o ashift=12 RAID0 /dev/sda /dev/sdb /dev/sdc /dev/sdd /dev/sde /dev/sdf /dev/sda is in use and contains a unknown filesystem. /dev/sdb is in use and contains a...

hmm, well I ran the "dd" on sda and either it really doesn't do anything, or it takes a really looooong time to complete. its been about 5 hours and nothing looks any different.

this is what you gave me: dd if=/dev/zero of=/dev/hdX where do I place the /dev/sda for example?

Originally they were on this server in a hardware RAID10 then added to a zfs pool. I broke the RAID and enabled JBOD on the server, ever since I can't get Proxmox to see them as available so I can add them to RAIDZ. I am remote worker now, thanks to COVID, but we are going back to office in a...

It does show differently in lsblk, but still doesn't cooperate: root@proxmox3:~# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 931.5G 0 disk └─35000c500b8ba5d47 253:4 0 931.5G 0 mpath sdb...

Tried that it, it doesn't change the status. They have no partition now that i can see. I assume I'm missing something that makes it "available", but can't figure it out. if you have a step by step sure fire way to do this, by all means let me know. I have already followed nearly every forum and...

I have these 6 drives that are all set "Device Mapper" for usage, and consequently not available to reuse for a new ZFS. I have looked for a fix on these forums to make them available but to no avail.
