udev: also autoactivate on coldplug
|
||||
|
||||
Commit 756bcabbfe297688ba240a880bc2b55265ad33f0 fixed autoactivation
|
||||
to not trigger on each uevent for a PV that appeared in the system
|
||||
most notably the events that are triggered artificially (udevadm
|
||||
trigger or as the result of the WATCH udev rule being applied that
|
||||
consequently generates CHANGE uevents). This fixed a situation in
|
||||
which VGs/LVs were activated when they should not.
|
||||
|
||||
BUT we still need to care about the coldplug used at boot to
|
||||
retrigger the ADD events - the "udevadm trigger --action=add"!
|
||||
|
||||
For non-DM-based PVs, this is already covered as for these we
|
||||
run the autoactivation on ADD event only.
|
||||
|
||||
However, for DM-based PVs, we still need to run the
|
||||
autoactivation even for the artificial ADD event, reusing
|
||||
the udev DB content from previous proper CHANGE event that
|
||||
came with the DM device activation.
|
||||
|
||||
Simply, this patch fixes a situation in which we run extra
|
||||
"udevadm trigger --action=add" (or echo add > /sys/block/<dev>/uevent)
|
||||
for DM-based PVs (cryptsetup devices, multipath devices, any
|
||||
other DM devices...).
|
||||
|
||||
Without this patch, while using lvmetad + autoactivation,
|
||||
any VG/LV that has a DM-based PV and for which we do not
|
||||
call the activation directly, the VG/LV is not activated.
|
||||
|
||||
For example a VG with an LV with root FS on it which is directly
|
||||
activated in initrd and then missing activation of the rest
|
||||
of the LVs in the VG because of unhandled uevent retrigger on
|
||||
boot after switching to root FS (the "coldplug").
|
||||
|
||||
(No WHATS_NEW here as this fixes the commit mentioned
|
||||
above and which was not released yet.)

udev: fire pvscan --cache properly on CHANGE event for MD devices
|
||||
|
||||
Commit 756bcabbfe297688ba240a880bc2b55265ad33f0 restricted the
|
||||
situations at which the LVM autoactivation fires - only on ADD
|
||||
event for devices other than DM. However, this caused a problem
|
||||
for MD devices...
|
||||
|
||||
MD devices are activated in a very similar way as DM devices:
|
||||
the MD dev is created on first appeareance of MD array member
|
||||
(ADD event) and stays *inactive* until the array is complete.
|
||||
Just then the MD dev turns to active state and this is reported
|
||||
to userspace by CHANGE event.
|
||||
|
||||
Unfortunately, we can't differentiate between the CHANGE event
|
||||
coming from udev trigger/WATCH rule and CHANGE event coming from
|
||||
the transition to active state - MD would need to add similar logic
|
||||
we already use to detect this in DM world. For now, we just have
|
||||
to enable pvscan --cache on *all* CHANGE events for MD so the
|
||||
autoactivation of the LVM volumes on top of MD works.
|
||||
|
||||
A downside of this is that a spurious CHANGE event for MD dev
|
||||
can cause the LVM volumes on top of it to be automatically activated.
|
||||
However, one should not open/change the device underneath until
|
||||
the device above in the stack is removed! So this situation should
|
||||
only happen if one opens the MD dev for read-write by mistake
|
||||
(and hence firing the CHANGE event because of the WATCH udev rule),
|
||||
or if calling udev trigger manually for the MD dev.
|
||||
|
||||
(No WHATS_NEW here as this fixes the commit mentioned
|
||||
above and which has not been released yet.)

Version 2.02.99 -
|
||||
===================================
|
||||
+ Fix premature DM version checking which caused useless mapper/control access.
|
||||
Recognize DM_DISABLE_UDEV environment variable for a complete fallback.
|
||||
Do not verify udev operations if --noudevsync command option is used.
|
||||
Fix blkdeactivate to handle nested mountpoints and mangled mount paths.

python-lvm: Implement proper refcounting for parent objects
|
||||
|
||||
Our object nesting:
|
||||
|
||||
lib -> VG -> LV -> lvseg
|
||||
-> PV -> pvseg
|
||||
|
||||
Implement refcounting and checks to ensure parent objects are not
|
||||
dealloced before their children. Also ensure calls to self or child's
|
||||
methods are handled cleanly for objects that have been closed or removed.
|
||||
|
||||
Ensure all functions that are object methods have a first parameter named
|
||||
'self', for consistency
|
||||
|
||||
Rename local vars that reference a Python object to '*obj', in order to
|
||||
differentiate from liblvm handles
|
||||
|
||||
Fix a misspelled pv method name
|
||||

||||

python-lvm: Remove liblvm object
|
||||
|
||||
Instead of requiring users to create a liblvm object, and then calling
|
||||
methods on it, the module acquires a liblvm handle as part of
|
||||
initialization. This makes it impossible to instantiate a liblvm object
|
||||
with a different systemdir, but there is an alternate envvar method for
|
||||
that obscure use case.

||||
