lvcreate/lvconvert: optionally reenable mirrored mirror log for testing purposes only This is a followup patch to commit edb72cb70cb8abd0acb92f07937715be2816d04a to support related lvm2 test suite tests. A 'global/support_mirrored_mirror_log' bool configuration variable gets introduced allowing the creation of, or conversion to mirrored 'mirror' logs if set. The capability to create these in turn allows the rest of the tests to perform activation of such existing LVs and their conversions to disk/core 'mirror' logs. Display a disclaimer warning if enabled that this is not for regular use. Add definition of the enabled config option to respective test scripts. Related: rhbz1643562

tests: rename test to inittest We are getting into problem when we use 'test' for commands like should/not/... So avoid overloading test name and change it to inittest.

aux lvmconf "global/support_mirrored_mirror_log=1"
Substantial rework of the functional test support code. Some new features: - somewhat neater, more consistent and more readable output - possible to set any lvm.conf value: aux lvmconf "section/key = value" - LVM_TEST_NODEBUG to suppress the (lengthy) "## DEBUG" output - back-substitution on test output ($TESTDIR/$PREFIX -> @TESTDIR@/@PREFIX@) - support code moved from test/ to test/lib/ --> less clutter

lvcreate -s $vg/lv -L 10M -n snap
Disallow snapshots of mirror segment types. Snapshots of RAID logical volumes are allowed (including "raid1"). However, snapshots of "mirror" logical volumes has been disallowed due to unsolvable issues inherent to the design. The fact that mirroring (dm-raid1.c) must stop all I/O as the result of a failure and wait for userspace intervention can lead to a circular dependency if userspace is simultaneously waiting for snapshots (on mirrors) to make an I/O update before proceeding. Various snapshot on mirror tests have been removed as a result.

# Down-convert (mirror -> linear) under a snapshot
lvconvert -m0 $vg/lv
# Up-convert (linear -> mirror)
TEST: Be explicit about which mirror segment type to use. In those places where mirrors were being created while assuming a default segment type of "mirror", we include the '--type mirror' argument to explicitly set the segment type. This will preserve the mirror testing that is performed even though the default mirroring segment type is now "raid1".

Add ability to create mirrored logs for mirror LVs. This check-in enables the 'mirrored' log type. It can be specified by using the '--mirrorlog' option as follows: #> lvcreate -m1 --mirrorlog mirrored -L 5G -n lv vg I've also included a couple updates to the testsuite. These updates include tests for the new log type, and some fixes to some of the *lvconvert* tests.

tests: more test run in cluster mode aux updates: prepare_vg now created clustered VG for cluster tests. since dm-raid doesn't work in cluster, skip the cluster test when someone checks for dm-raid target until fixed.
