[SOLVED] raid1 and luks/dm-crypt not working after upgrade

hello folks,

i just made a pacman -Syu, which also updated mdadm and cryptsetup (not the kernel). but after a reboot, the system didn't boot any more. after #'ing the cryptsetup-relevant lines in /etc/crypttab and /etc/fstab, the system booted again. after a check, i get those messages:

~ $ cat /proc/mdstat 
Personalities : [raid1] 
md1 : active raid1 sdd1[0] sde1[1]
      390707641 blocks super 1.2 [2/2] [UU]
      
md0 : active raid1 sdb1[0] sdc1[1]
      1465134841 blocks super 1.2 [2/2] [UU]
      
unused devices: <none>

~ $ sudo cryptsetup luksOpen /dev/md0 data
Passwort: 
Geben Sie den Passsatz für /dev/md0 ein: 
semid 65537: semop failed for cookie 0xd4d2ffb: incorrect semaphore state
Failed to set a proper state for notification semaphore identified by cookie value 223162363 (0xd4d2ffb) to initialize waiting for incoming notifications.

what happened and how to fix it?
i didn't change anything. so it shouldn't be anything about modules or whatever.

EDIT: okay, it's not aboud the raid, but about the cryptsetup version. see below.

Got the same problem here: It fails with

semid 1048580: semop failed for cookie 0xd4d3177: incorrect semaphore state
Failed to set a proper state for notification semaphore identified by cookie value 223162743 (0xd4d3177) to initialize waiting for incoming notifications.

when i try to do

cryptsetup -c aes-xts-plain -s 512 luksFormat /dev/md0

Ive created a bug report on: https://bugs.archlinux.org/task/22351 since this obviously has been a bug some weeks ago: https://bbs.archlinux.org/viewtopic.php?id=108003

Re: [SOLVED] raid1 and luks/dm-crypt not working after upgrade

thank you. i have also seen the other thread, but since it used to work for me until the update, i am not quite sure whether it is the same issue...lets see...

EDIT: okay, downgrading to cryptsetup-1.1.3-1-x86_64 solved the problem. maybe its another implementation in 1.2.0.1?

BTW:

dbus and hal cannot be the problem: i am starting cryptsetup before starting dbus and hal.

Re: [SOLVED] raid1 and luks/dm-crypt not working after upgrade

SOLVED!

It works again with the new version of the device-mapper: 2.02.81 (no unknown semaphore state anymore).

But also the crypttab syntax has changed. After removing the options in crypttab, cryptsetup 1.2.0-1 works again.

Old crypttab file:
# NAME     SOURCE DEVICE     PASSWORD     OPTIONS
#home     /dev/sda4     ASK     -c aes-xts-plain -s 512
#data     /dev/md0     ASK     -c aes-xts-plain -s 512

New crypttab file:
# NAME     SOURCE DEVICE     PASSWORD     OPTIONS
home     /dev/sda4     ASK
data     /dev/md0     ASK

Have a look at https://bugs.archlinux.org/task/22351
