multipath-tools 0.9.7

[mwilck]

Summary: Important changes in 0.9.7

• the options bindings_file, wwids_file and prkeys_file, which were deprecated since 0.8.8, have been removed. The path to these files is now hard-coded to $(statedir) (see below).
• added max_retries config option to limit SCSI retries
• added auto_resize config option to enable resizing multipath maps automatically
• added support for handling FPIN-Li events for FC-NVMe
• rework of alias selection code:
  • strictly avoid using an alias that is already taken
  • cache bindings table in memory
  • write bindings file only if changes have been applied, and watch it with inotify
  • sort aliases in "alias order" by using length+alphabetical sort, allowing more efficient allocation of new aliaes
  • fix memory and error handling of code using aio in the marginal paths code and the directio checker (fixes #73).
• avoid that multipath -d changes sysfs settings
• insert compile time settings for paths in man pages correctly
• add new compile-time variable statedir which defaults to /etc/multipath
• add new compile-time variable etc_prefix as prefix for config file and config dir
• compile-time variable usr_prefix now defaults to /usr if prefix is empty.
• remove check whether multipath is enabled in systemd .wants directories
• README improvements
