Description Pranith Kumar K 2016-10-18 17:34:21 UTC 
We introduced two new options:
1) disperse.shd-max-threads: This option can be used to increase the number of parallel heals per EC subvolume.
2) disperse.shd-wait-qlength: This option can be used to control number of heals that can wait in SHD per EC subvolume.

We need to document these options for 3.2.0.
Comment 7 Pranith Kumar K 2016-11-15 08:17:04 UTC 
disperse.shd-max-threads
Specifies the number of entries that can be self healed in parallel on each
disperse subvolume by self-heal daemon.
Valid values: 1-64
Default value: 1

disperse.shd-wait-qlength
Specifies the number of entries that must be kept in the queue for self-heal
daemon threads to take up as soon as any of the threads are free to heal.
This value should be changed based on how much memory self-heal daemon
process can use for keeping the next set of entries that need to be healed.
Valid values: 1 - 655536
Default value: 1024
