Can reproduce this issue on RHEL8.8 with the following steps:
Steps:
1.
# yum install device-mapper-multipath
2.
# mpathconf --enable
3.
# augtool -s set "/files/etc/multipath.conf/blacklist/wwid" ".*"
error: Failed to execute command
saving failed (run 'errors' for details)
4.
# augtool print /augeas//error | grep multipath.conf
/augeas/files/etc/multipath.conf/error = "parse_failed"
/augeas/files/etc/multipath.conf/error/pos = "317"
/augeas/files/etc/multipath.conf/error/line = "14"
/augeas/files/etc/multipath.conf/error/char = "0"
/augeas/files/etc/multipath.conf/error/lens = "/usr/share/augeas/lenses/dist/multipath.aug:133.10-.64:"
/augeas/files/etc/multipath.conf/error/lens/last_matched = "/usr/share/augeas/lenses/dist/multipath.aug:24.24-.42:"
/augeas/files/etc/multipath.conf/error/lens/next_not_matched = "/usr/share/augeas/lenses/dist/multipath.aug:16.10-.37:"
/augeas/files/etc/multipath.conf/error/message = "Iterated lens matched less than it should"
5.
# cat /etc/multipath.conf
# device-mapper-multipath configuration file
# For a complete list of the default configuration values, run either:
# # multipath -t
# or
# # multipathd show config
# For a list of configuration options with descriptions, see the
# multipath.conf man page.
defaults {
user_friendly_names yes
find_multipaths yes
enable_foreign "^$"
}
blacklist_exceptions {
property "(SCSI_IDENT_|ID_WWN)"
}
blacklist {
}
In fact, augeas cannot parse 'enable_foreign "^$"' this line in /etc/multipath.conf file. This line doesn't exist in /etc/multipath.conf on RHEL9.
(In reply to Martin Hoyer from comment #0) > Description of problem: > augtool does not seem to function properly when modifying multipath.conf > For triaging / prioritization purposes, can you state if this is impacting anything on top of it (i.e., any script / program / routine that is trying to perform this change and failing)? Thanks I don't know any other example then our kernel/storage python tests, which enable multipath this way. In past we were using custom multipathd.conf file, but switch to running `mpathconf --enable` recently. The workaround (deleting 'enable_foreign "^$"' line) is simple enough so there is no real impact here. Looking at the multipath-aug source it looks like the last commit was in 2018 to fix and issue reported also by me :) https://github.com/hercules-team/augeas/issues/583 i.e. I wouldn't say this needs to have any priority. fyi, opened an issue upstream: https://github.com/hercules-team/augeas/issues/808 |
