I have created a ZFS test pool with a drive - now I have pulled thet drive out and want to format it to EXT4 and use it outside of ZFS. I think the pool wasn't properly destroyed.
Now when I plug the drive into a different machine running ZFS - the drive is reported by dmesg to be accessible under /dev/sdf, but lsblk won't list it, and trying to access the /dev/sdf node returns an error:
# mkfs.ext4 /dev/sdf mke2fs 1.42.13 (17-May-2015) Could not open /dev/sdf: No medium found
The node exists:
# file /dev/sdf /dev/sdf: block special (8/80)
lsblk and gparted doesn't list it:
# lsblk | grep sdf *nothing returned*
Here's dmesg output:
# dmesg | tail [256646.291063] usb 4-5: New USB device found, idVendor=125f, idProduct=a15a [256646.291064] usb 4-5: New USB device strings: Mfr=2, Product=3, SerialNumber=1 │ [256646.291065] usb 4-5: Product: HD710 [256646.291065] usb 4-5: Manufacturer: ADATA [256646.291066] usb 4-5: SerialNumber: 02730010002900000022 [256646.291784] usb-storage 4-5:1.0: USB Mass Storage device detected [256646.291913] scsi host8: usb-storage 4-5:1.0 [256647.350854] scsi 8:0:0:0: Direct-Access ASMT 2105 0 PQ: 0 ANSI: 5 [256647.352164] sd 8:0:0:0: Attached scsi generic sg5 type 0 [256647.353125] sd 8:0:0:0: [sdf] Attached SCSI removable disk
How can I format this drive? Can I do it in a machine using ZFS?
