  • Automount LUKS Volume fails

    Posted on

    I built a RHEL 6u4 64 system as a lab for the RHCSA but the LUKS filesystem will not automount. The host was installed with the virtual host profile in the anaconda installer.

    I can successfully mount the filesystem manually with the following: (This appears to be whats broken with init)

    [root@kauai ~]# cryptsetup luksOpen /dev/sdb1 cryptLV
    Enter passphrase for /dev/sdb1: 
    [root@kauai ~]# blkid
    /dev/sda2: UUID="bb098ec9-b535-4f3a-8f02-a3db2a9a08c9" TYPE="ext4" 
    /dev/sda1: UUID="fcd19106-34c5-4593-bf30-3ef3f90b1aaf" TYPE="swap" 
    /dev/sdb1: UUID="d07c1901-4940-4944-8e33-e34c2b49f543" TYPE="crypto_LUKS" 
    /dev/mapper/cryptLV: UUID="c96a5e58-3f3b-4ab3-8eb4-afbb4d32fcf6" TYPE="ext4"
