I’m trying to clear up the mess left when I tried experimenting with
encrypting a spare partition/filesystem with YaST.
Basically YaST threw up errors when I tried to encrypt a partition without
formatting it but on a retry (apparently) succeeded in formatting and
encrypting it together and gave me a /dev/mapper/cr_sdc1 entry (both without
mounting the partition).
I had to reboot to get the new partition available for mounting but it
seemed to be Ok but confused me by asking for a passphrase for cd_sdc1
during boot even though it wasn’t being mounted.
When I tried to unencrypt the partition YaST threw up enough wobblies that I
ended up having to reboot (mostly to clear a spurious mount and busy message
for the fs) and then formatted it directly from a terminal with mkfs.
I still have /dev/mapper/cr_sdc1 and keep getting asked for a passphrase for
it on boot.
Just to make life interesting the partition was /dev/sdc1 when I did this
because I had an external HDD connected at boot which went in as /dev/sda.
At the last boot the external USB wasn’t recognised so the partition I was
playing with is now at /dev/sdb1. YaST’s partitioner shows /dev/sdb1 as
encrypted. Attempting to mount /dev/sdb1 comes up with /dev/sdb1 already
mounted or the mountpoint is busy, umount says not mounted and fuser doesn’t
show any users.
Can I just delete /dev/mapper/cr_sdc1 without screwing up my system?
