Now all of the 8 disks are 10TB and I do not intend to do a dd of the whole disk, because that's 14hours for each disk, so I'd really appreciate if someone has an idea how to achieve a wipe. * dd if=/dev/zero of=/dev/sda bs=1M count=1000 -> no errors (obviously), Proxmox GUI after reload still shows disk as ddf_raid_member * wipefs -fa /dev/sda -> no errors, Proxmox GUI after reload still shows disk as ddf_raid_member apparently wipefs did not delete it (i wiped with 'wipefs -a -f /dev/diskid') im not sure if this is expected/by design, but i would expect that wipefs would remove such.

This division is recorded in the partition table, usually found in sector 0 of the disk. after wiping a disk with wipefs, im re-creating a partition/filesystem and fdisk is telling that a freshly created partition contains a zfs signature. util-linux is a standard package distributed by the Linux Kernel Organization for use as. Block devices can be divided into one or more logical disks called partitions. It understands GPT, MBR, Sun, SGI and BSD partition tables. Of course you may see that different, because Virtual Environment 7.0-8 is flawless and bug-free already. fdisk is a dialog-driven program for creation and manipulation of partition tables.

In order to achieve this, you should do step by step to practice more. However, the earlier Fdisk has no format functions to meet your requirements of formatting partitions and allocating file systems after dividing.

fdisk will ask you to remove existing filesystems.

I/O size (minimum/optimal): 512 bytes / 512 bytes parted doesnt have an option for removing the filesystem, you can use wipefs before running the command. Sector size (logical/physical): 512 bytes / 512 bytes wipefs can erase filesystem, raid or partition-table signatures (magic strings) from the specified device to make the signatures invisible for libblkid.

I could do wipefs from CLI but works only if I add -a and -f flags.īack to web gui, I tried again and get the same error.ĭisk /dev/sdb: 200 GiB, 214748364800 bytes, 419430400 sectorsĭisk model: VBOX HARDDISK => As you can see, I was testing in VirtualBox.
