# When there are cloned devices (same pvid), one will be referenced in
|
|
# lvmcache as pv->dev, and the other will not be referenced from lvmcache,
|
|
# it'll only be in device cache. The one referenced by lvmcache is
|
|
# referred to as the "preferred" one, and is the one that is printed by a
|
|
# standard 'pvs' command.
|
|
#
|
|
# We don't know if dev1 or dev2 will be preferred, so we first check that
|
|
# and save it as PV1, the other as PV2.
|
|
#
|
|
# The rules that 'pvs' follows to choose which PVs to display are
|
|
# somewhat strange and seem arbitrary from a user perspective;
|
|
# the choice is driven largely by what's most practical in the code,
|
|
# but also by what vgimportclone needs.
|
|
#
|
|
# Some of the rules that process_each_pv is using:
|
|
# - When no pv arg is specified, print the one preferred dev.
|
|
# - When pv args are specified, print one line per specified arg,
|
|
# i.e. don't print all duplicate pvs when one is specified.
|
|
# - Always print the preferred duplicate, even if it was not the
|
|
# one specified, e.g. If there are two duplicates on A and B,
|
|
# and A is the preferred device, then 'pvs A' will show A and
|
|
# 'pvs B' will show A.
|
|
# - If multiple duplicates are specified, then print each, e.g.
|
|
# 'pvs A B' will show both A and B.
|
|
# - If three duplicates exist on A, B, C, and the preferred is A,
|
|
# and the command 'pvs B C' is run, then the A will be printed
|
|
# first since we always print the preferred device, and then
|
|
# either B or C will be printed. 'pvs A B C' will print all.
|
|
# - 'pvs -a' should print all the duplicates and should show
|
|
# the same VG for each.
|
|
# - 'pvs -o+size ...' should show the correct size of the
|
|
# devices being printed if they differ among the duplicates.
|
|
# - By using 'pvs --config' with a filter, you can filter out
|
|
# the duplicate devs you don't want so that pvs will
|
|
# print the devs you do want to see.
|
|
#
|
|
# The tests below check these behaviors on up to two duplicates,
|
|
# so if the process_each_pv logic changes regarding which
|
|
# duplicates are chosen, then this test will need adjusting.
|
|
|
|
# Verify that there is only one PV printed, i.e. the preferred
|

# TODO: I'd like to test that a subsystem device is preferred
|
|
# over a non-subsystem device, but all the devices used here
|
|
# are DM devices, i.e. they are already subsystem devices,
|
|
# so I can't just wrap a standard block device with a DM

# identity mapping.
