multipath.conf file content¶
The base class is the MultipathConfParser class, which reads the multipath
daemon’s /etc/multipath.conf
configuration file.
This is in a pseudo-JSON format.
MultipathConf - file /etc/multipath.conf

MultipathConfInitramfs - command lsinitrd -f /etc/multipath.conf

- class insights.parsers.multipath_conf.MultipathConf(context)[source]¶
Bases:
MultipathConfParser
Parser for the file
/etc/multipath.conf
.Examples
>>> conf = shared[MultipathConf] >>> conf.data['blacklist']['devnode'] # Access via data property '^hd[a-z]' >>> conf['defaults']['user_friendly_names'] # Pseudo-dict access 'yes' >>> len(conf['multipaths']) 2 >>> conf['multipaths'][0]['alias'] 'yellow'
- class insights.parsers.multipath_conf.MultipathConfInitramfs(context)[source]¶
Bases:
MultipathConfParser
Parser for the output of
lsinitrd -f /etc/multipath.conf
applied to /boot/initramfs-<kernel-version>.img.Examples
>>> conf = shared[MultipathConfInitramfs] >>> conf.data['blacklist']['devnode'] # Access via data property '^hd[a-z]' >>> conf['defaults']['user_friendly_names'] # Pseudo-dict access 'yes' >>> len(conf['multipaths']) 2 >>> conf['multipaths'][0]['alias'] 'yellow'
- class insights.parsers.multipath_conf.MultipathConfParser(context)[source]¶
Bases:
Parser
,LegacyItemAccess
Shared parser for the file
/etc/multipath.conf
and output oflsinitrd -f /etc/multipath.conf
applied to /boot/initramfs-<kernel-version>.img.Return a dict where the keys are the name of sections in multipath configuraion file. If there are subsections, the value is a list of dictionaries with parameters as key and value. Otherwise the value is just a single dictionary.
Configuration File Example:
defaults { path_selector "round-robin 0" user_friendly_names yes } multipaths { multipath { alias yellow path_grouping_policy multibus } multipath { wwid 1DEC_____321816758474 alias red } } devices { device { path_selector "round-robin 0" no_path_retry queue } device { vendor 1DEC_____321816758474 path_grouping_policy red } } blacklist { wwid 26353900f02796769 devnode "^hd[a-z]" }
Parse Result:
data = { "blacklist": { "devnode": "^hd[a-z]", "wwid": "26353900f02796769" }, "devices": [ { "path_selector": "round-robin 0", "no_path_retry": "queue" }, { "path_grouping_policy": "red", "vendor": "1DEC_____321816758474" } ], "defaults": { "path_selector": "round-robin 0", "user_friendly_names": "yes" }, "multipaths": [ { "alias": "yellow", "path_grouping_policy": "multibus" }, { "alias": "red", "wwid": "1DEC_____321816758474" } ] }
