[PATCH 0/5] multipath: Add a group_by_tgp path grouping policy

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

 



This patchset is adds a new path grouping policy that can be used with
ALUA devices. The goal is to avoid the temporary incorrect path
groupings that can happen when paths change priorities.

There is one thing that I'm not sure of.  Is there any possiblity of a
path device changing the target port group it belongs to while it use?
If so, then we would need code to check for this and reload the device
if it occurs.

Benjamin Marzinski (5):
  libmultipath: add group_by_tpg path_grouping_policy
  libmultipath: don't copy pgpolicy string in get_pgpolicy_name
  libmultipath: add ALUA tpg path wildcard
  multipath-tools tests: add tests for group_by_tpg policy
  libmultipath: add "detect_pgpolicy" config option
