Like nodes, drives may be smartfailed and down, or smartfailed but available. The group statement looks similar to that for a smartfailed or down node, only the drive Lnum is also included. For example:
{ 1-4:0-23, 5:0-6,8-23, 6:0-17,19-24, down: 5:7, soft_failed: 5:7 }
This indicates that node ID 5 drive Lnum 7 is both SmartFailed and unavailable.
If the drive was SmartFailed but still available, the group would read:
{ 1-4:0-23, 5:0-6,8-23, 6:0-17,19-24, soft_failed: 5:7 }.
When multiple devices are down, consolidated group statements can be tricky to read. For example, if node 1 was down, and drive 4 of node 3 was down, the group statement would read:
{ 2:0-11, 3:0-3,5-11, 4-5:0-11, down: 1, 3:4, soft_failed: 1, 3:4 }
However, if node 1 was up but drive 4 on node 1 was down, the group statement would read:
{ 1:0-3,5-11, 2:0-11, 3:0-3,5-11, 4-5:0-11, down: 1,3:4, soft_failed: 1,3:4 }
