Subject: [PATCH 553/584] cluster/ec: Change self-heal-window-size to 4MiB by
|
|
|
c460ee |
default (#2071)
|
|
|
c460ee |
|
|
|
c460ee |
The current block size used for self-heal by default is 128 KiB. This
|
|
|
c460ee |
requires a significant amount of management requests for a very small
|
|
|
c460ee |
portion of data healed.
|
|
|
c460ee |
|
|
|
c460ee |
With this patch the block size is increased to 4 MiB. For a standard
|
|
|
c460ee |
EC volume configuration of 4+2, this means that each healed block of
|
|
|
c460ee |
a file will update 1 MiB on each brick.
