The lvm dbus daemon will auto activate on dbus API calls. To
prevent the dbus daemon starting when lvm command line tools are
being used we will check to see if the daemon is running first.
If the daemon is not running, we will not notify the daemon.
For this check to work it requires the changes done previously

The number of extents for the sanlock lvmlock lv is calculated using
integer division, which rounds towards zero. With a physical extent size
of 129M, instead of the requested 256M the lv is only 129M (1 extent).
With any physical extent size greater than 256M the lv creation fails
because the number of extents is zero.
This is fixed by replacing the integer division with a division macro
that rounds up and thus guarantees that the size of the lv will always
be equal or greater than the requested size. Using the examples above, a
pes of 129M will result in a 258M lv (2 extents), pes of 300M in a 300M
lv (1 extent).
The re-calculation of the lv size in bytes and megabytes is only so the
debug output shows the correct values. The size in mb there is still
not byte-perfect-accurate, but good enough for a human-readable estimate;
and the exact size in bytes and extents is right next to it.

When executing process_each_lv_in_vg, we process live LVs first and
after that, we process any historical LVs. In case we have just removed
an LV, which also means we have just made it "historical" and so it
appears as fresh item in vg->historical_lvs list, we have to skip it
when we get to processing historical LVs inside the same process_each_lv_in_vg
call.
The simplest approach here, without introducing another LV list, is to
simply mark such historical LVs as "fresh" directly in struct
historical_logical_volume when we have just removed the original LV
and created the historical LV for it. Then, we just need to check the
flag when processing historical LVs and skip it if it is "fresh".
When we read historical LVs out of metadata, they are marked as
"not fresh" and so they can be processed as usual.
This was mainly an issue in conjuction with -S|--select use:
# lvmconfig --type diff
metadata {
record_lvs_history=1
}
(In this example, a thin pool with lvol1 thin LV and lvol2 and lvol3 snapshots.)
# lvs -H vg -o name,pool_lv,full_ancestors,full_descendants
LV Pool FAncestors FDescendants
lvol1 pool lvol2,lvol3
lvol2 pool lvol1 lvol3
lvol3 pool lvol2,lvol1
pool
# lvremove -S 'name=lvol2'
Logical volume "lvol2" successfully removed.
Historical logical volume "lvol2" successfully removed.
...here, the historical LV lvol2 should not have been removed because
we have just removed its original non-historical lvol2 and the fresh
historical lvol2 must not be included in the same processing spree.
The new device_id types are: wwid_naa, wwid_eui, wwid_t10.
The new types use the specific wwid type in their name.
lvm currently gets the values for these types by reading
the device's vpd_pg83 sysfs file (this could change in the
future if better methods become available for reading the
values.)
If a device is added to the devices file using one of these
types, prior versions of lvm will not recognize the types
and will be unable to use the devices.
When adding a new device, lvm continues to first use sys_wwid
from the sysfs wwid file. If the device has no sysfs wwid file,
lvm now attempts to use one of the new types from vpd_pg83.
If a devices file entry with type sys_wwid does not match a
given device's sysfs wwid file, the sys_wwid value will also
be compared to that device's other wwids from its vpd_pg83 file.
If the kernel changes the wwid type reported from the sysfs
wwid file, e.g. from a device's t10 id to its naa id, then lvm
should still be able to match it correctly using the vpd_pg83
data which will include both ids.
t10 wwids are now edited in the same way that multipath does,
which is replacing a series of spaces with one _. Previously
lvm replaced every space with one _. Devices file entries
with the old form will be converted to the new shorter form.
Move the functions handling dev wwids.
Add dev flags indicating that wwids have been read from
sysfs wwid file or sysfs vpd_pg83 file. This can be
used to avoid rereading these.
Improve filter-mpath search for a device's wwid in
/etc/multipath/wwids, to avoid unnecessary rereading
of wwids from sysfs files.
Type 8 wwids from vpd_pg83 with naa or eui names should be
saved as those types.
If lvmlockd in cluster is killed accidently or any other reason, the
lock resources will become orphaned in the VG lockspace. When the
cluster manager tries to restart this daemon, the LVs will probably
become inactive because of resource schedule policy and thus the lock
resouce will be omited during the adoption process. This patch will
try to purge the lock resources left in previous lockspace, so the
following actions can work again.
Exclude the new fs resizing capabilities at build time
(rather than run time) if the necessary libblkid features
are not available. When excluded, all fs resizing options
are translated to resize_fsadm. Accessing the new
features now requires rebuilding lvm if libblkid is
upgraded.
Place the addCleanup at the end as we don't want to go through clean up
if we don't make it through setUp. If we don't do this we can remove VGs
that we didn't create in the unit test.
Previously when the __del__ method ran on LVMShellProxy we would blindly
call terminate(). This was a race condition as the underlying process
may/maynot be present. When the process is still present the SIGTERM will
end up being seen by lvmdbusd too. Re-work the code so that we
first try to wait for the child process to exit and only then if it hasn't
exited will we send it a SIGTERM. We also ensure that when this is
executed we will briefly ignore a SIGTERM that arrives for the daemon.
If we plan to use dm throttling for mirror targets - we actually
have to check whether kernel runs with CONFIG_HZ_1000 - if it does
not the whole idea of throttling is actually not working in the
testsuite as within a single 'tick' with HZ 100 way too much date
is being moved on any modern hardware - and since there is no plan
to change this in kernel - we simply avoid using throttling on such
kernel and test needs to work differently - either ignore results
or use much larger mirror sizes...
When checking to see if the PV is missing we incorrectly checked that the
path_create was equal to PV creation. However, there are cases where we
are doing a lookup where the path_create == None. In this case, we would
fail to set lvm_id == None which caused a problem as we had more than 1
PV that was missing. When this occurred, the second lookup matched the
first missing PV that was added to the object manager. This resulted in
the following:
