[PATCH 2/7] FIX: monitor doesn't handshake with md

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



when in container are present raid0 and raid5 arrays, and reshape order is:
1. raid0 array
2. raid5 array

mdadm cannot set new raid_disks for raid0 array. For this action md has to have
handshake with mdmon. We have the following conditions:
1. Raid0 is not monitored
2. raid0 has been just takeovered to raid4/5 (it has to be monitored
3. monitor has to start monitor new raid4/5 array
4. monitor is not started (it is started to second raid5 array)
In such situation pig_monitor is required to let know to m monitor about new array
(not in the starting monitor case only)
