[lvm-devel] [PATCH 0/2] LVM2: fix lvmetad udev rules for CHANGE events

[Martin Wilck]

The current logic in 69-dm-lvm-metad.rules is broken for the default
"enable-udev-systemd-background-jobs" case. Detailed information about the
problem can be found in the commit message of the 2nd patch in the set.
That patch also contains the tiny actual change of this patch set: if systemd
background jobs are active, the variables SYSTEMD_ALIAS and SYSTEMD_WANTS are
also set for CHANGE events, not only for ADD.

The reason that the patch set is quite large nonetheless is that I wanted
the comments in the rules file to match the actual behavior. Substitution of
multi-line comments is very hard, if not impossible, with the string
substitution approach in the current Makefile. That necessitates the first
patch, which introduces no functional change.

  lvm2: 69-dm-lvm-metad.rules: explicit pvscan rule
  lvm2: 69-dm-lvm-metad.rules: set systemd vars on "change"
