[Bug 719388] Re: semop failed for cookie 0xd4d09ef: incorrect semaphore state during luksOpen

[Linus van Geuns]

I am geting semaphore errors, too.

Setup:
- internal disk SATA
- external disk eSATA
- GPT -> LVM -> LUKS (cryptsetup)

When creating logical volumes, I get:
> "The link /dev/ext0/exttest2 should had been created by udev but it was not found. Falling back to direct link creation."
When removing logical volumes, I get semaphore errors.
When doing luksOpen/luksClose on existing LVMs, I get semaphore errors.

I will attach package & setup information and output of lvcreate -vvvv
and lvremove -vvvv.

  semop failed for cookie 0xd4d09ef: incorrect semaphore state during
  luksOpen

Status in “cryptsetup” package in Ubuntu:
  Fix Released

Bug description:
  Binary package hint: cryptsetup

  Hi,
    I'm doing

  sudo cryptsetup luksOpen /dev/mapper/mydevice myuncrypted

  and it's working but giving the following warnings:

  semid 393218: semop failed for cookie 0xd4d1f7f: incorrect semaphore state
  Failed to set a proper state for notification semaphore identified by cookie value 223158143 (0xd4d1f7f) to initialize waiting for incoming notifications.

  the values change each time, but it seems to be unlocking the
  partition and it seems to work OK.
