wipefs -n /dev/sd
Already done?There might be an easier way.
Already transferred data and am wiping now.
I ran wipefs -n /dev/sdb on my data drive that is working and my output is:
root@openmediavault:~# wipefs -n /dev/sdb
offset type
----------------------------------------------------------------
0x200 gpt [partition table]
0x747024ff000 zfs_member [filesystem]
Does this indicate that there are still some zfs files on my disk?
