Commit 3f35146 added a check on the value returned by the
_display_info_cols() function:
1024 if (!_switches[COLS_ARG])
1025 _display_info_long(dmt, &info);
1026 else
1027 r = _display_info_cols(dmt, &info);
1028
1029 return r;
This exposes a bug in the dmstats code in _display_info_cols:
the fact that a device has no regions is explicitly not an error
(and is documented as such in the code), but since the return
code is not changed before leaving the function it is now treated
as an error leading to:
# dmstats list
Command failed.
When no regions exist.
Set the return code to the correct value before returning.
The device-mapper directory now holds a copy of libdm source. At
the moment this code is identical to libdm. Over time code will
migrate out to appropriate places (see doc/refactoring.txt).
The libdm directory still exists, and contains the source for the
libdevmapper shared library, which we will continue to ship (though
not neccessarily update).
All code using libdm should now use the version in device-mapper.
As we start refactoring the code to break dependencies (see doc/refactoring.txt),
I want us to use full paths in the includes (eg, #include "base/data-struct/list.h").
This makes it more obvious when we're breaking abstraction boundaries, eg, including a file in
metadata/ from base/
Recent changes allow some major simplification of the way
lvmcache works and is used. lvmcache_label_scan is now
called in a controlled fashion at the start of commands,
and not via various unpredictable side effects. Remove
various calls to it from other places. lvmcache_label_scan
should not be called from anywhere during a command, because
it produces an incorrect representation of PVs with no MDAs,
and misclassifies them as orphans. This has been a long
standing problem. The invalid flag and rescanning based on
that is no longer used and removed. The 'force' variation is
no longer needed and removed.
btrfs is using fake major:minor device numbers.
try to be smarter and detect used node via DM device name.
This shortens delays, where i.e. lvm2 is asked to deactivate
volume with mounted btrfs as such operation is not retryed
and user is informed about device being in use.
When function dm_stats_populate() returns 0 it's an error and needs
log_error() message - function can't have 'success' returning 0 or
error without reasons.
When doing resume, directly pass location where new updated info
needs to be stored.
_resume_node() ensures the info is ONLY updated when the function
is successful and never changes it on error path.
Update the logic towards more explicit logic.
Preload tree normally does not want to resume, only
in certain cases of extension or new loaded nodes can be
resumed. So introduce new internal variable delay_resume_if_extended
controlable by target.
Patch itself is not changing current existing behaviour,
and rather documents existing problem in more readable way.
lvm2 needs to introduce explicit mechanism how to support more
fain-grained (and safe) logic to i.e. resize thin-pool which
can be sitting on cached raid volume.
Variable props.send_messages has 3 states and was not used properly
here. Activation in this moment does not need to verify thin-pool status
as that has been already checked on preload.
So only if there are some real messages (value 2) call function
for sending them.
Code already has dereferenced UUID before this point,
and its already given we require name & uuid when ading new node
(although uuid could be empty string).
Just like everywhere else - use single if() for major:minor setup
(it basically can't fail as of today anyway)
Always leave funtion with correctly set pointers even on error path.
Replicator never really existed in upstream kernel and its support
got deprecated.
Also its support never got finished so no code is supposed to be
using it anyway.
Libdm symbols are remaining, just the implementation will always
return failure - so any user of:
dm_tree_node_add_replicator_dev_target()
dm_tree_node_add_replicator_target().
will now always recieve error message.
Separate handling of error code from _info_by_dev.
This error can only happeng when we are running out of memory.
In such case there is urgent need to stop any futher proceeding
of command and run to error ASAP.
ATM we want to support delayed resume purely in pvmove case.
So have libdm logic internal to recognize difference beween
pvmove and other targets that do use delayed resume.
This fixes problem introduced with commit aa68b898ff
for mirror-on-mirror or snapshot-on-mirror problem.
TODO: likely added new API call and let libdm user select
delayed nodes explicitely.
