Hello, i was using cryptsetup processes without any problem before. I changed the usb memory and encrypted it again. But after the encryption, the cryptsetup open command does not show dev/ mapper/disk1 in block info.
That's why problem with mount command,
How to fix this, thanks for your help.
Usually you are mounting device' partitions like sda1 and not sda directly. Same for creating/opening a cryptdevice. I would assume the error there.
But why does cryptsetup open command not add /dev/mapper/disk1 to block info command?
Because cryptsetp device is not a block device. If you want to see ("virtual") devices also use e. g.: "fdisk -l"
You should elaborate what you want to achive exactly. And as mounting from /dev/mapper/disk1 is failing I would check if your filesystem is supported or you have created one on disk1.
I understand, but that's not exactly the problem, "cryptsetup open" command creates the encrypted device virtually on /dev/mapper/ ... directory, no problem here. The same command adds block info command /dev/mapper/ ... directory, but it doesn't show up in block info command
I see that the cryptdevice is open and mounting is failing with "invalid argument".
So what is "fdisk -l" or cat /proc/partitions actually showing? block is not showing all!
Works for me:
dd if=/dev/zero of=/crypto bs=1M count=100
cryptsetup luksFormat /crypto
cryptsetup luksOpen /crypto open
mkfs.ext4 /dev/mapper/open
mount /dev/mapper/open /mnt
block info
