in clvmd, dmevend, man, tests.
Don't include dependency files for clow and cscope.out targets
Improve dependency tracking for dmeventd and liblvm2cmd sources.
This check-in enables the 'mirrored' log type. It can be specified
by using the '--mirrorlog' option as follows:
#> lvcreate -m1 --mirrorlog mirrored -L 5G -n lv vg
I've also included a couple updates to the testsuite. These updates
include tests for the new log type, and some fixes to some of the
*lvconvert* tests.
clvmd's do_lock_lv() already properly controls dmeventd monitoring based
on LCK_DMEVENTD_MONITOR_MODE in lock_flags -- though one small fix was
needed for this to work: _lock_for_cluster() must treat
dmeventd_monitor_mode()'s return as a tri-state value.
Also cleanup do_lock_lv() to:
- explicitly init_dmeventd_monitor() based on LCK_DMEVENTD_MONITOR_MODE
- no longer reset init_dmeventd_monitor() to default at the end of
do_lock_lv() -- it is unnecessary
This is the next preparatory step towards better --alloc anywhere
support and is not intended to break anything that currently works so
please report any problems - segfaults, bogus data in the new debug
messages, or if the code now chooses bizarre allocation layouts.
. Add "monitoring" option to "activation" section of lvm.conf
. Have clvmd consult the lvm.conf "activation/monitoring" too.
. Introduce toollib.c:get_activation_monitoring_mode().
. Error out when both --monitor and --ignoremonitoring are provided.
. Add --monitor and --ignoremonitoring support to lvcreate. Update
lvcreate man page accordingly.
. Clarify that '--monitor' controls the start and stop of monitoring in
the {vg,lv}change man pages.

Prevent lvresize from being able to resize internal LVs: mirror legs
(*_mimage_*), mirror log (*_mlog), snapshot placeholder LVs (snapshot*)
and others. Resizing these would leads to unexpected metadata and
sometimes crashes (in case of growing snapshot*).
This option should be configurable, but for now
do not set it at all.
(lvm2app is used in udisks probers and there
cac cause several nasty races when trying to update
lvmcache during rescan.)
If user try to vgcreate or vgextend non-existent VG,
these messages appears:
# vgcreate xxx /dev/xxx
Internal error: Volume Group xxx was not unlocked
Device /dev/xxx not found (or ignored by filtering).
Unable to add physical volume '/dev/xxx' to volume group 'xxx'.
Internal error: Attempt to unlock unlocked VG xxx.
(the same with existing VG and non-existing PV & vgextend)
# vgextend vg_test /dev/xxx
...
It is caused because code tries to "refresh" cache if
md filter is switched on using cache destroy.
But we can change filters and rescan even without this
machinery now, just use refresh_filters
(and reset md filter afterwards).
(Patch also discovers cache alias bug in vgsplit test,
fix it by using better filter line.)
This patch adds a new implementation of locking function instead
of mlockall() that may lock way too much memory (>100MB).
New function instead uses mlock() system call and selectively locks
memory areas from /proc/self/maps trying to avoid locking areas
unused during lock-ed state.
Patch also adds struct cmd_context to all memlock() calls to have
access to configuration.
For backward compatibility functionality of mlockall()
is preserved with "activation/use_mlockall" flag.
As a simple check, locking and unlocking counts the amount of memory
and compares whether values are matching.
For static builds dependency for SELinux libs is not handled by 'ar'.
Till better solution is found, for static builds STATIC_LIBS is used.
Patch updates SELinux detection to use 3rd & 4th parameter for Success/Fail.
Also removes detection of pthread from this check as we know which
version of libdevmapper we are going to link with lvm after merge.
SELinux header check moved to the SELinux test code.
Create new substituted variable PTHREAD_LIBS and link this library
only with tools/libs which really needs it - i.e. dmeventd.
Check for libpthread only for builds with clvmd or dmeventd.
Remove variable LIB_PTHREAD
The kernel's blk_stack_limits() function may flag a device as
'misaligned'. If it does the alignment_offset will be -1.
Update set_pe_align_offset() to accommodate this corner case.
- increase timeout to 30 secs (on Chrissie request)
- source both cluster and clvmd for options (like all the other cluster
init scripts)
- add clustered_vgs and _lvs commodity fns
- move rh_status* fns at the top, so they can be reused
- heavily cleanup start and stop fns from redundant code and unnecessary
loops
- improve output from different operations
- make the init script lsb compliant
- don´t force kill of the daemon, send only a TERM signal and then wait
for it to exit
- Resolves rhbz#533247
lvm2 devices have always UUID set even if imported from lvm1 metadata.
Patch removes name argument from dev_manager_info call and converts
all activation related calls to use query by UUID.
Also it simplifies mknode call (which is the only user on mknodes parameter).
