Option --all is only partially documented currently, so document in all
commands. Also make {pv|vg|lv}{display|s} man pages consistent with help
output. Remove ununsed 'disk_ARG' parameter. Leave --trustcache out of
the man page output. Update --units argument to show all possible units.
- we have these levels when the udev rules are processed:
10-dm.rules --> [11-dm-<subsystem>.rules] --> [12-dm-permissions.rules] -->
13-dm-disk.rules --> [...all the other foreign rules...] --> 95-dm-notify.rules
- each level can be disabled now by
DM_UDEV_DISABLE_{DM, SUBSYSTEM, DISK, OTHER}_RULES_FLAG
- add DM_UDEV_DISABLE_DM_RULES_FLAG to disable 10-dm.rules
- add DM_UDEV_DISABLE_OTHER_RULES_FLAG to disable all the other (non-dm) rules.
We cutoff these rules by using the 'last_rule', so this one should really be
used with great care and in well-founded situations. We use this for lvm's
hidden and layer devices now.
- add a parameter for add_dev_node, rm_dev_node and rename_dev_node so it's
possible to switch on/off udev checks
- use DM_UDEV_DISABLE_DM_RULES_FLAG and DM_UDEV_DISABLE_SUBSYSTEM_RULES_FLAG
if there's no cookie set and we have resume, remove and rename ioctl.
This could happen when someone uses the libdevmapper that is compiled with
udev_sync but the software does not make use of it. This way we can switch
off the rules and fallback to libdevmapper node creation so there's no
udev/libdevmapper race.
- remove default permissions set in 95-dm-notify.rules (and add a hint in 12-dm-permissions.rules to set it by the user directly)
- add multipath DM_ACTION=="PATH_FAILED" filter
- remove unnecessary filters in the headers of the rules (we can simply use DM_UDEV_RULES_VSN instead)
- fix symlink priorities in /dev/disk/ (snapshot volumes have low priority for FS UUID symlinks so it will not overwrite symlinks for the origin)
[root@xxxx-01 ~]# lvconvert -m 1 --corelog VG/cmirror
Unable to convert the log of inactive cluster mirror cmirror
I've tried to clean-up the message a little more, so the name
of the mirror stands out more while preserving the sense that
it's not a problem with the specific device, but the fact that
it is inactive that is causing the problem.
New msg:
Unable to convert the log of an inactive cluster mirror, cmirror
Per discussion on lvm-devel mailing list and part of debian patch set,
don't set defaults for owner and group, since nobody seems to use them, and
still allow override.
Going forward, we would like to allow users to specify the total
number of metadatacopies in a VG rather than on a per-PV basis. In
order to facilitate that, introduce --pvmetadatacopes to replace
--metadatacopies everywhere. We still allow --metadatacopies for
pv commands, but require --pvmetadatacopies for vg commands.
Eventually we will introduce --vgmetadatacopies. Once we do that,
we should either deprecate --metadatacopies or make it a synonym based
on the command (pvmetadatacopies for pv commands, and vgmetadatacopies
for vg commands). The latter option would likely just require a simple
'strncpy' check against cmd->command->name to qualify the merge_synonym
call.
Update nightly tests to cover the pvmetadatacopies synonym.
Note that this patch is the result of an eariler review comment for
the implicit pvcreate patches. Should apply cleanly on top of the
implicit pvcreate patches (I applied after patch 10/10 in that series).
NOTE: This patch will require --pvmetadatacopies for vgconvert as
--metadatacopies is no longer accepted.

vgcreate and vgextend now implicitly call pvcreate on devices not
currently initialized for LVM use. Previously these commands would
fail with an error, so clarify the new behavior in the man page.
Adds implicit pvcreate support when calling vgcreate or vgextend with
device paths that are not yet PVs. This changes the behavior of vgcreate
and vgextend from failing with an error message to implicitly pvcreating.
Split pvcreate_validate_params into recovery and non-recovery parameters.
This is necessary so we can call the non-recovery validate function from
vgextend / vgcreate. Note in the pvcreate tool case, we must call the
recovery validation function first (see treatment of pe_start and --zero),
and that we add a call to fill_default_pvcreate_params before the validation
functions.
We need defaults for pvcreate_params at a higher level - this will
allow us to use a common function from the tools to take defaults,
then fill in any non-defaults from the commandline.
Future patches will refactor vgcreate/vgextend to call this function
if one or more pvcreate parameters are given on the commandline.
Another refactoring for implicit pvcreate support. We need to get
the pvcreate parameters somehow to the vg_extend routine. Options
seemed to be:
1. Attach the parameters to struct volume_group. I personally
did not like this idea in most cases, though one could make an
agrument why it might be ok at least for some of the parameters
(e.g. metadatacopies).
2. Pass them in to the extend routine. This second route seemed
to be the best approach given the constraints.
Future patches will parse the command line and fill in the actual
values for the pvcreate_single call.
Should be no functional change.
Should be no functional change. If this parameter is set to NULL, just fail
the extend if the device is not already a PV. If non-NULL, try pvcreate_single
before failing. Note that pvcreate_single() handles the log_error in case
of failure so we just return 0 if pvcreate_single() fails.
