Normally, restart simply means "stop and start" for systemd. However, if
we're installing new versions of the dmeventd binary/libdevmapper, we need
to restart dmeventd. This fails if we have some devices monitored - we need
to call "dmeventd -R" instead.
The "ExecReload" did not work quite well in some old versions of systemd,
systemd assumed that only the configuration is reloaded on "ExecReload",
not the whole binary itself so it lost track of dmeventd daemon (it lost new
dmeventd PID). This is fixed and seems to be working fine now with recent
versions of dmeventd.
When fsadm is test - it needs to execute lvm and fsadm from non-standard path
setting. So adding a support in fsadm script when user set LVM_BINARY, then
the lvm command invoced from fsadm will have the same PATH setting as before
entering fsadm command.
Needed for testing.
In case someone would use filename paths with spaces when changing
this script surround commands with '"'.
With default settings there is no change in behavior.
Some major distributions are still using 'mawk' and they are not using
the latest version - we end here with hidden dependency on the latest
version of mawk (1.3.4) while i.e. Debian Lenny seems to stay with 1.3.3.
So we end with completely broken vgimportclone script on such system.
We would need to check for proper support of :space: and abort build if
it doesn't work or simplier replace [:space:] with [ \t] which seems
sufficient to make it work (as can be seen in this patch)
A better fix would be to use command line parameter override - leaving
as FIXME comment.
This patch makes t-vgimportclone.sh test passing on Lenny.
Copy this file as '.gdbinit' to your home directory or your working
directory. It adds the following commands to gdb:
- first_seg
- lv_status
- lv_status_r
- lv_is_mirrored
- seg_item
- seg_status
- segs_using_this_lv
You can get a list of these user-defined commands by typing:
(gdb) help user-defined
You can get more information on each command by typing:
(gdb) help <command>
It would be most useful to add "dmsetup ls --tree" to the commands run.
This command helps in answering the question "which devices are actually
underneath a given LV?"
Although the info is available with other existing dmsetup commands,
adding this command gives a much clearer summary of complex setups.
Here's an example of an LVM mirror, with mirror images on partitions
created on top of multipath devices. The multipath devices are on
simple block devices. As you can see, it is easy to see the stacking
from the "dmsetup ls --tree" output:
vgmpathtest-lvmpathmir (253:14)
├─vgmpathtest-lvmpathmir_mimage_1 (253:13)
│ └─mpath5p1 (253:5)
│ └─mpath5 (253:2)
│ ├─ (8:16)
│ └─ (8:0)
├─vgmpathtest-lvmpathmir_mimage_0 (253:12)
│ └─mpath6p1 (253:6)
│ └─mpath6 (253:3)
│ ├─ (8:48)
│ └─ (8:32)
└─vgmpathtest-lvmpathmir_mlog (253:11)
└─mpath7 (253:4)
├─ (8:80)
└─ (8:64)
VolGroup00-LogVol01 (253:1)
└─ (202:2)
vgtest-lvmir (253:10)
├─vgtest-lvmir_mimage_1 (253:9)
│ └─ (7:1)
├─vgtest-lvmir_mimage_0 (253:8)

└─vgtest-lvmir_mlog (253:7)

VolGroup00-LogVol00 (253:0)
└─ (202:2)
But it is much harder to see the stacking with only the commands today
("dmsetup info", "dmsetup status", and "dmsetup table"). We could
piece together the stacking from "dmsetup table" but it requires
further processing (take output from "dmsetup info to get
map name to major/minor, then parse "dmsetup table", etc).
Fix for the last commit as $MOUNTED is not only used as bool flag,
but also store mounted location for remount - so parsing output
from mount differently then from /proc/mounts.
Prefix calls of 'tunefs' tools with LANG=C to be sure we always do get
some nonlocalized strings.
Avoid using forced 'resize2fs' for cleanly unmounted filesystems and
run regular fsck -f for this case as required by resize2fs.
'fsadm check' uses date difference for extX filesystems between
the last mount and last check of 'fsck -f' execution and if the mount
was later run 'fsck' with -f so resize2fs is happy and user does not
need to pass '-f' flag.
As util-linux package seems to give all the time different names,
try harder to figure out, where is the given lv possible mounted
and scan /proc/mounts and if not found there, test also 'mount' output.
/dev/dm-xxx
/dev/mapper/vg-lv
/dev/vg/lv
All of them could be used different combination in /proc/mount and mount output.
Patch fixes regression for older systems where new detection code failed to
find valid combination.
Updated patch from Florian Haas from Linux-HA project.
User needs to 'configure --enable-ocf' to get file installed
by 'make install' target by default.
User can also use 'make install_ocf' to get only ocf files installed.
With disabled (default) ocf support - no ocf files are installed.
FIXME: ocf installation path needs to be kept in sync with pacemaker.
find better way and possible also better location.
Return status code 3 for fsadm check of mounted filesystem - used later with
lvresize update patch to better support online filesystem resize.
Also makes a more consistent user interruption and returns status code 2
in this case.
Try to distinguish between the case of using interactive shell and non
interactive running - different combinations of '-y' and '-p' option
needs to be used for fsck.
Update the way how fsadm detects mounted filesystem.
With udev /dev/dm-XXX paths are now returned - but mount or /proc/mounts
prints names in form of /dev/mapper/vg-lv - so the match was not found.
Fixex RHBZ #638050.
Current solution uses same trick as mount and detects vg-lv name through
/sys where available - this should be reasonable safe.
Instead of calling mount without parameter to get actual mount table,
switch to use /proc/mounts directly.
Fix missing 'dry' execution of lvresize - fixing problem where resize
command were 'dry-run' executed - but lvresize has been executed for real.
Also adapt code slightly to support better recursive execution of fsadm
through lvresize call.
Under certain conditions it was possible to break (^C) fsadm before actually
resizing filesystem, but lvresize which executed fsadm will think resize
was succesful and shrinks partitions with unresized filesystem on it.
Fix by returning error (1) for this case - this stops lvresize from futher
proceding in resize operation.
set appropriate Required-Start and Required-Stop at configure time.
Reorder the checks for user selected cluster managers to match auto
detected ones, to be consistent in the output.
Add special case for qdiskd that´s started after cman/lock_gulmd for
RHEL-4/RHEL-5.
clvmd daemon itself does the right thing when invoked as non-root, by
returning 4.
The patch removes the use daemon function from
/etc/rc.d/init.d/functions that´s unnecessary and has th bad habit to
mask the return codes from the real daemon.
Add a simple and generic check to see if clvmd is executed by root or not.
Our stop/reload/restart paths in the init script are complex and not all
the tools involved in the process are guaranteed to return 4 if executed
by non-root against a process that´s running as root (for example kill
-TERM will return -1 and parsing the output to catch the error is
suboptimal at best).

- s/Active clustred VG/clustered VG/ (only LV can be active)

(In the lvdisplay form /dev/vg/lv.)
For now, still use awk (already used in clustered_vgs).

length(array) is specific to GNU awk and doesn't work in mawk.
Use a return value of "split" function to indicate array size, this is
supported in both gawk and mawk.
This patch fixes the following errors during "make install" when mawk is
installed as a default awk.
