Re: [dm-crypt] dmsetup or cryptsetup hangs in the initrd

I guess you are missing dmsetup udev rules in initramfs
or something like that. (Hint: just add --debug to cryptsetup and it will show where is is waiting.)

You should probably use systemd to activate crypt devices in RHEL7 anyway.

Using hardcoded sdb1 is wrong, it will overwrite other disk if you e.g. forget
USB drive plugged in. Use some hw id symlink.

Run dracut shell, debug it by hand.
