Description Karel Zak 2010-11-23 19:08:55 UTC 
Description of problem:

#!/bin/bash
losetup -d /dev/loop7 &> /dev/null

rm /etc/blkid/blkid.tab
blkid &> /dev/null

dd if=/dev/zero of=tst bs=1M count=64
losetup /dev/loop7 tst

echo "--- Luks ---"
echo "password" | cryptsetup luksFormat /dev/loop7
blkid /dev/loop7

echo "--- PV ---"
pvcreate -ff /dev/loop7
blkid /dev/loop7

echo "--- done ---"
losetup -d /dev/loop7


... this script has to return info about LUKs as well as about LVM.

Old version:

  --- Luks ---
  /dev/loop7: UUID="53b65aab-0b55-480b-ae90-8d773d4686a2" TYPE="crypto_LUKS" 
  --- PV ---
    Physical volume "/dev/loop7" successfully created
  --- done ---

New version:

   --- Luks ---
   /dev/loop7: UUID="53b65aab-0b55-480b-ae90-8d773d4686a2" TYPE="crypto_LUKS" 
   --- PV ---
     Physical volume "/dev/loop7" successfully created
   /dev/loop7: UUID="mmjW2c-NsCh-bE6y-0I7G-oxt1-Yre4-SXVe96" TYPE="LVM2_member"
   --- done ---

The problem is that libblkid incorrectly revalidated cache entries.

Fixed by upstream commit e8fc977aba09ddbd89b25276fd777c3f0eef9299.
