I just thought this story might be interesting. Boot is now normal speed, and gparted finds my 7 partitions now. Yes I had to type the whole 90 lines of wipefs. So back to SystemRescueCD, and do from there wipefs -o 0x7dc00 /dev/sda Wipefs: error: /dev/sda: probing initialization failed: Device or resource busyīut, hang on, the disk is mounted and it can not do it from within Debian Run 'ceph-disk zap' command failed with dmcrypt osd disk: Raw. We can use wipefs to remove these zfs signatures as follows wipefs -o 0x7dc00 /dev/sda Sda 0x1fe lists many items that are called signatures… most of them zfs_member, but at the end my GPT partition table, another copy of the GPT partition table at the top of the disk, and the PMBR (protective MBR). probing initialization failed: Device or resource busy sudo wipefs -all -f /dev/sr0 wipefs: error: /dev/sr0: probing initialization failed: Read-only. Now, wipefs sounds like a dangerous tool, and it is, so another clonezilla backup first. much research, and I finally find a tool called wipefs which I can use to check the disk. What is going on? There must be some residue of ZFS on the disk?. when I looked at the disk from within Debian, with the Gnome-disk-utility, it looked normal, but when I looked with gparted it said the entire disk was one ZFS partition!.wipefs: error: /dev/sda: probing initialization failed: No medium found The. Then a reboot showed that i had a grub menu and could boot from that. Wiping all existing partition table and filesystem signatures in /dev/sda.
Wipefs probing initialization failed install#
So then from within Debian I could configure grub with update-grub. option Downloading install image Wiping /dev/sdb wipefs: error: /dev/sdb: probing initialization failed: Permission denied Writing disk image dd: failed. From there I booted Debian with grub> linux /vmlinuz root=/dev/sda4Īnd Debian booted. Then I could reboot and get the grub> prompt. Used SystemRescueCD for that.Īlso had to remove grub.cfg from the Debian filesystem, because I had reinstalled Debian to a different partition.Īlso had to edit /etc/fstab to fix the UUID’s Went ahead with clonezilla and restored my Debian filesystem and my data filesystem. I did that with gparted…made a GPT partition table and created 7 partitions … EFISystem, bios-boot, 4 x ext4 partitions, and a swap partiton. So I had to put the partitions back before I could restore filesystems. They were saveparts images - ie images of partitions. It wrote a ZFS filesystem all over my 500Gb SSD… wiped everything, even grub on the MBR.įortunately I had clonezilla backups. I was looking a TRUEOS DVD and I thought it was a live system, but it was an install DVD.

To wipe out just the Master boot record (MBR), run: sudo wipefs -all -backup /dev/sdb wipefs: error: /dev/sdb: probing initialization failed: Device or resource busy this is while none of the partitions on.
$ sudo dd if=/dev/urandom of=/dev/vdb bs=1M status=progress
in the terminal, I get the following error: wipefs: error: /dev/sdb: probing initialization failed: Device or resource busy. I screwed it up and now I need to reset the flash drive. I attempted to create a bootable arch linux usb using dd as outlined here. OR do secure erase with dd command showing progress bar: Help using wipefs to reset a flash drive. The dd command works on Linux, FreeBSD, MacOS and Unix-like operating system. You can also use the dd commandt o wipe out a signature from a disk device using the following syntax. You will also find a signature backup file with the following ls command: Sample outputs: /dev/vdb: 8 bytes were erased at offset 0x00000218 (LVM2_member): 4c 56 4d 32 20 30 30 31 Restores an ext2 signature from the backup file ~/wipefs-sdb-0x00000438.bak $ sudo wipefs -all -force -backup /dev/vdb You can create a signature backup to the file $HOME/wipefs-.bak: How do I erase current signatures from /dev/vdb? Make sure you use correct device names with the wipefs command.
