Hello, i hope my first post is helpful.
After some debugging i figured out where this error message "cryptsetup:
unknown fstype, bad password or options?" in my case comes from.
The point is that i am having a LVM Partition which holds several
logical volumes which need to be mounted (at least one of them as root
partition). This partition seems not to be visible/available at this
time.
I patched the script and the error is gone for me. So can someone please check
and confirm that this helps?!
It would then be great to get this fixed for future versions because i do not
want to use a self-patched version which will be overwritten with some new
updates.
To sum up. This are the problems with that i think
1) "cryptsetup: unknown fstype, bad password or options?"
Problem: LVM Partitions not fully set up at the time the script tries to detect
the File-System type.
Solution: Wait until all partitions fully set up and accessible
2) "device-mapper: remove ioctl on sda5_crypt failed: Device or resource busy"
This error is shown because of the Problem in "1)" because the File-System is
not being detected (due to empty FSTYPE variable)
3) /run/lvm/lvmetad.socket: connect failed: No such file or directory +
WARNING: Failed to connect to lvmetad. Falling back to internal
scanning.
This warning comes from /etc/lvm/lvm.conf because in this configuration file
"use_lvmetad" is activated and set to 1.
Having this enabled seems to be fine i think. The problem is that this daemon
is not running at the time the lvm commands from the initramfs-tools are being
executed.
I solved this "optical problem" of displaying this warnings by creating
a hook, which set the use_lvmetad to "use_lvmetad = 0".
$ cat /etc/initramfs-tools/hooks/fix_lvm2_hook
#!/bin/sh
PREREQ="lvm2"
prereqs()
{
echo "$PREREQ"
}
case $1 in
prereqs)
prereqs
exit 0
;;
esac
. /usr/share/initramfs-tools/hook-functions
if [ -e ${DESTDIR}/etc/lvm/lvm.conf ]; then
# Replace use_lvmetad=1 with use_lvmetad=0
sed -E 's/(^\s*use_lvmetad\s*=\s*)(1)(\s*.*$)/\10\3/'
${DESTDIR}/etc/lvm/lvm.conf
fi
