Hi all, I am using Arch. In the middle of last year I successfully wiped two partitions on my laptop following the instructions here: https://wiki.archlinux.org/index.php/Dm-crypt/Drive_preparation#dm-crypt_wipe_on_an_empty_disk_or_partition This year I decided to wipe the remaining partition on the same laptop using the same command command but it fails as below. Any ideas? ~/ lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT nvme0n1 259:0 0 931.5G 0 disk ├─nvme0n1p1 259:1 0 1G 0 part /boot ├─nvme0n1p2 259:2 0 50G 0 part │ └─arch-root 254:0 0 50G 0 crypt / ├─nvme0n1p3 259:3 0 700G 0 part ├─nvme0n1p4 259:4 0 176.5G 0 part │ └─arch-home 254:2 0 176.5G 0 crypt /home └─nvme0n1p5 259:5 0 4G 0 part └─swap 254:1 0 4G 0 crypt [SWAP] █▓▒░root@thinkpad-p43s█▓▒░ Wed 13/Jan/2021 08:26:53.073 ~/ cryptsetup open --type plain -d /dev/urandom /dev/nvme0n1p3 to_be_wiped device-mapper: reload ioctl on failed: No such file or directory ~/
