- add copyright notice for 10-dm.rules.in,
- set DM_UDEV_DISABLE_{DISK, OTHER}_RULES_FLAG in 11-dm-lvm.rules directly
for inappropriate and non-top-level subdevices in case we use older kernels
where DM_COOKIE is not used (and therefore there are no flags passed from
the LVM process itself). This applies for older kernels (version < 2.6.31),
- remove unnecessary filters in 95-dm-notify.rules - the DM_COOKIE env var
itself is set for change/remove udev events and for DM devices only so
there's no need to double-check this.
Similar to other vg_set_* functions, we create a vg_set_clustered() function
which does a few checks and sets a flag. This is where we check for
any limitations of clusters.
The DRBD uses underlying device so code should prefer top
device if duplicate is found.
Patch also introduce
dev_subsystem_part_major and dev_subsytem_name
functions to easily handle all these replication susbystems
and not hardcode md_major call.
See https://bugzilla.redhat.com/show_bug.cgi?id=530881
for full problem description.
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.
