get_block_for_mdraid

Description:

[ Version ( since = "2.1" ) ]
public Block get_block_for_mdraid (MDRaid raid)

Gets the RAID device (e.g. /dev/md0) for raid.

In the case of a split-brain syndrome, it is undefined which RAID device is returned. For example this can happen if /dev/sda and /dev/sdb are components of a two-disk RAID-1 and /dev/md0 and /dev/md1 are two degraded arrays, each one using exactly one of the two devices. Use get_all_blocks_for_mdraid to get all RAID devices.

Parameters:

this	A Client.
raid	A MDRaid.

Returns:

A Block or null if no RAID device is running.
