HDD/Partition initialization problems

[jaker]

attached wipefs from util-linux-2.30
To be installed in /usr/sbin (and make executable with chmod)

Sorry I didn't manage to download this directly to NAS. RZ for receiving ZMODEM transfer over SSH does not exist and wget doesn't seem to be able to handle forum attachments. That "plugout download " method or direct link to file seemed to work. Could you copy the file to location without login?

I ended up trying filetransfer.io service and got the file downloaded. Here's the output.

To download it using method describe by Jocko use as id 6474

Actually I first did this to wrong NAS. :D and had to remove text and do it again. Here you go.

[fvdw]

Seems there is a zfs_member signature besides ext4

Try to erase it using

Code: Select all

wipefs -a -t zfs_member /dev/sda8

[Jocko]

After running it, see what is now blkid output

Code: Select all

blkid /dev/sda8

and also mount command

Code: Select all

mkdir /tmp/sda8
mount /dev/sda8 /tmp/sda8

umount /tmp/sda8

[jaker]

Well that doesn't seem to do anything. Wonder what's wrong with this now. It does not seem to remove zfs_member.

Code: Select all

root@fvdwsl-base:/tmp # wipefs /dev/sda8

Clearly mounting does not do anything either.

I wonder why it does not print any errors. Perhaps I should try -f parameter?

Code: Select all

root@fvdwsl-base:/tmp # wipefs

Usage:
 wipefs [options] <device>

Wipe signatures from a device.

Options:
 -a, --all           wipe all magic strings (BE CAREFUL!)
 -b, --backup        create a signature backup in $HOME
 -f, --force         force erasure
 -h, --help          show this help text
 -n, --no-act        do everything except the actual write() call
 -o, --offset <num>  offset to erase, in bytes
 -p, --parsable      print out in parsable instead of printable format
 -q, --quiet         suppress output messages
 -t, --types <list>  limit the set of filesystem, RAIDs or partition tables
 -V, --version       output version information and exit

For more details see wipefs(8).
root@fvdwsl-base:/tmp #


Force does not change the results

Code: Select all

root@fvdwsl-base:/tmp # wipefs -a -f -t zfs_member /dev/sda8
root@fvdwsl-base:/tmp # wipefs /dev/sda8
offset               type

I found this, so clearly someone else is also having same problem. https://bugs.debian.org/cgi-bin/bugrepo ... bug=856833

These might be useful, but I hesitated to try these on my own.
Using dd to erase:

Yes try the -f parameter
You could also try

Code: Select all

wipefs -a -f /dev/sda8

This should remove all sgnatures so also ext4
But I assume you have no data stored on sda8 so you can create it again by using format command

[fvdw]

The offset mentioned for zfs_member converted to decimal is 1997426864128 bytes so somewhere at the end of the disk. I wonder how it came there??. Was this disk used in another computer?

[fvdw]

You can also try

Code: Select all

wipefs -o 1997426864128
