2 dm-era
8 dm-era is a target that behaves similar to the linear target. In
10 defined period of time called an 'era'. Each era target instance
11 maintains the current era as a monotonically increasing 32-bit
21 era <metadata dev> <origin dev> <block size>
38 Possibly move to a new era. You shouldn't assume the era has
40 current era via the status line.
56 <current era> <held metadata root | '-'>
63 current era The current era
78 - Send a checkpoint message to the era target
79 - Make a note of the current era in its status line
80 - Take vendor snapshot (the era and snapshot should be forever
90 by checking each block's era
97 The target uses a bitset to record writes in the current era. It also
98 has a spare bitset ready for switching over to a new era. Other than
107 block is performed. As such dm-era should not be effected by a hard
