Subject: [PATCH] multipath.conf(5): remove io-affinity information
|
|
|
e71b65 |
|
|
|
e71b65 |
The multpath-tools do not support the io-affinity path selector. We
|
|
|
e71b65 |
always add a repeat count as the path argument. The io-affinity selector
|
|
|
e71b65 |
doesn't take one. Instead it takes a bit map of CPUs that a path can
|
|
|
e71b65 |
run on. This isn't something that lends itself to the kind of
|
|
|
e71b65 |
auto-assembling that multipathd does. But even if we did want to
|
|
|
e71b65 |
try to support this path-selector, until we do, we shouldn't be listing
|
|
|
e71b65 |
it in the multipath.conf documentation.
