I am trying to encrypt the /tmp partition on a server after it had been configured. I wasn't able to setup up encrypt at install as it wouldn't allow for using a random key. Instead, I created the /tmp-tmp LVM formated as ext and of a size 10G. After I made the changes to the /etc/fstab and /etc/crypttab files, the server started to hang and I've had to use the install disk to boot into maintenance mode to try and resolve the issue.
enc_t /dev/mapper/tmp-tmp /dev/urandom tmp,cipher=aes-xts-plain64,size=512,hash=sha512
/dev/mapper/enc_t /tmp ext4 relatime,async,nosuer,noauto,noatime,nodiratime,nosuid,noexec,nodev,rw 0 0
I have taken a look at the /var/log/messages and dmesg files but didn't see any errors. Can anyone assist with what I did wrong?
