NAME

       ocf_heartbeat_crypt - LUKS/crypt resource agent

SYNOPSIS

       crypt [start | stop | monitor | meta-data | validate-all]

DESCRIPTION

       This is a LUKS/crypt Resource Agent managing encrypted devices via cryptsetup(8). The
       agent imposes limitations on device types supported: luks, luks[1..N].

SUPPORTED PARAMETERS

       encrypted_dev
           Encrypted backing device, which should be defined by UUID, 36 characters including
           '-'s as reported by blkid(8).

           Although it can be defined as a block device path (e.g. /dev/sdh), the UUID should be
           preferred over the block device path to allow for the unique discovery of the crypt
           backing device given the volatile nature of /dev entries (e.g. /dev/sdh on one node
           may be /dev/sdg on another).

           Only define as block device path if you know what you are doing.

           (unique, required, string, no default)

       crypt_dev
           Encrypted device name, no path. I.e. the one given in "cryptsetup open name ...". The
           resulting block device path is /dev/mapper/name.

           (unique, required, string, no default)

       key_file
           Key file path containing the encryption passphrase (aka key; see cryptsetup(8)). For
           LUKS, the passphrase as of the key_file parameter is used to decrypt a randomly
           selected key when the device was created.

           (required, string, no default)

       crypt_type
           Encryption (device) type (e.g. "luks" or "luks2").

           This parameter affirms the encryption format as of the crypt metadata thus allowing
           for safety measures when starting the encrypted resource.

           (required, string, no default)

       force_stop
           If processes or kernel threads are using the crypt device, it cannot be stopped. We
           will try to stop processes, first by sending TERM and then, if that doesn't help in
           seconds, using KILL. The lsof(8) program is required to get the list of array users.
           Of course, the kernel threads cannot be stopped this way. If the processes are
           critical for data integrity, then set this parameter to false. Note that in that case
           the stop operation will fail and the node will be fenced.

           (optional, boolean, default false)

SUPPORTED ACTIONS

       This resource agent supports the following actions (operations):

       start
           Starts the resource. Suggested minimum timeout: 20s.

       stop
           Stops the resource. Suggested minimum timeout: 20s.

       monitor
           Performs a detailed status check. Suggested minimum timeout: 20s. Suggested interval:
           10s.

       meta-data
           Retrieves resource agent metadata (internal use only). Suggested minimum timeout: 5s.

       validate-all
           Performs a validation of the resource configuration. Suggested minimum timeout: 10s.

EXAMPLE CRM SHELL

       The following is an example configuration for a crypt resource using the crm(8) shell:

           primitive p_crypt ocf:heartbeat:crypt \
             params \
               encrypted_dev=string \
               crypt_dev=string \
               key_file=string \
               crypt_type=string \
             op monitor timeout="20s" interval="10s" depth="0"

EXAMPLE PCS

       The following is an example configuration for a crypt resource using pcs(8)

           pcs resource create p_crypt ocf:heartbeat:crypt \
             encrypted_dev=string \
             crypt_dev=string \
             key_file=string \
             crypt_type=string \
             op monitor timeout="20s" interval="10s" OCF_CHECK_LEVEL="0"
