When the backup is disabled, avoid testing backup presence.
This only leads to errors being logged in debug trace and the missing
backup can't be fixed, since it's disabled.
Check whether lvm dumpconfig --mergedconfig is used only
with --type current (where we're merging current config and
the config supplied on command line). With other types
the config was merged, but it was thrown away since we're
generating other type of config anyway. This lead to a memleak.
Error out if --mergedconfig is used with anything else than
--type current (or without specifying --type in which case
the --type current is used by default).
Decorate NULL returns with debug_cache output so the
debug log doesn't contain spurios <bactrace> line without
any reason for it.
Add internal errors when cache is misused.
The global/suffix was missing from example lvm.conf but it can
be very useful when using lvm in scripts and now in profiles as well
Let's expose it more.
man/lvm2-activation-generator.8:
Generator Specification -> Generators Specification
(this is the exact word in the systemd man page)
conf/example.conf.in:
cleanup recent edits related to report section
man/lvm.conf.5:
add a line about a possibility to generate a new
profile with lvm dumpconfig command as an alternative
to copying the default profile
Delay archiving of metadata until we really start to
update metadata when converting volume into a snapshot.
Archive is not necessary when we abort operation early.
Do not allow conversion of too small LV into a COW snapshot device.
Without this patch snapshot target is generating these kernel
messages before creation fails:
attempt to access beyond end of device
dm-9: rw=16, want=8, limit=2
attempt to access beyond end of device
...
device-mapper: table: 253:11: snapshot: Failed to read snapshot metadata
device-mapper: ioctl: error adding target to table
device-mapper: reload ioctl on failed: Input/output error
Create a separate function to validation snapshot min chunk value
and relocate code into snapshot_manip file.
This function will be shared with lvconvert then.
Usage of origin as a snapshot 'COW' volume is unsupported.
Without this test lvm2 is able to generate this ugly internal error message.
To test this:
lvcreate -L1 -n lv1 vg
lvcreate -L1 -n lv2 -s vg/lv1
lvcreate -L1 -n lv3 vg
lvconvert -s vg/lv3 vg/lv1
Internal error: LVs (5) != visible LVs (1) + snapshots (1) + internal LVs (0) in VG vg
Users can create several profiles for how the tools report
the output very easily and then just use
<lvm reporting command> --profile <report_profile_name>
We need to use "--verifyudev" for dmsetup mangle command used in
the name-mangling test since without the --verifyudev, we'd end up
with the failed rename.
Also, add direct check for the dev nodes - node with old name must
be gone and node with new name must be present. Before, we checked
just the output of the command.
One bug popped up here when renaming with udev and libdevmapper
fallback checking the udev when target mangle mode is "none"
(fixme added in the libdevmapper's node rename code).
This prevents numerous VG refreshes on each "pvscan --cache -aay" call
if the VG is found complete. We need to issue the refresh only if the PV:
- is new
- was gone before and now it reappears (device "unplug/plug back" scenario)
- the metadata has changed
"%d" in buffer_append_vf is 64 bit wide. Using just `int` for the
variable will fetch more from va_list than intended and shifting
remaining arguments resulting in errors like:
Internal error: Bad format string at '#orphan'
This breaks brew/koji as DESTDIR should not be contained in any file and
results in message like:
+ /usr/lib/rpm/check-buildroot
/builddir/build/BUILDROOT/lvm2-2.02.106-0.311.el7.x86_64/usr/share/man/man8/lvm2-activation-generator.8:.B /builddir/build/BUILDROOT/lvm2-2.02.106-0.311.el7.x86_64/usr/lib/systemd/system-generators/lvm2-activation-generator
Found '/builddir/build/BUILDROOT/lvm2-2.02.106-0.311.el7.x86_64' in installed files; aborting
error: Bad exit status from /var/tmp/rpm-tmp.UfX2SX (%install)
Reorder detection for internal device - since this test
is much simpler then target analysis, check it sooner.
Replace test for '68' with sizeof & ID_LEN
Add FIXME about device alias problem with is_reserved_lvname,
since this test fails on devices like /dev/dm-X
so we need to convert tests to UUID.
Let's do this the other way round - this makes more logic than commit b995f06.
So let's allow empty values for global/thin_disabled_features where
such an empty value now means "none of this features are disabled".
The global/thin_disabled_features should be marked as having no default
value. Otherwise the output from 'lvm dumpconfig --type default' would
have 'thin_disabled_features=""' which will produce an error message
'Ignoring empty string in config file ...' if such output is feed
back to lvm.
