3cce4419c2 Adding section number for lvm.conf manpages. 2010-06-22 07:34:34 +00:00

bc59859a59 Mirrors can be layered - as in the case of an converting 2-way
to 3-way mirror.  When conversion operations are performed on
these types of mirrors, log options can be confused/ignored.

In the case of a converting 3-way mirror, we have a top-level
2-way corelog mirror whose legs are 1) a 2-way disk-log mirror
and 2) a linear device.  If we wish to convert this 3-way mirror
to a 2-way mirror, the linear device is removed and the extra
top layer is eliminated.  If we also wished to convert the disk
log to a core log in the same step, ambiguity creeps in.  It is
somewhat obvious what the user wants - a 2-way mirror with a
corelog.  However, looking at the top level mirror before
compression, it seems that the mirror already has a core log.
This is why the operation seemed to fail.

This patch simply re-evaluates what mirrored_seg points to after
a compression and then considers the log argument.

This is a fix for bug 599898.

aa9797fa3c Let running clvmd process time to reexec.
Because execve stops the command loop,
we never receive response (only socket close) for clvmd -S,
so waiting for response here makes no sense.

But if the calling process (clvmd -S)  exits too early, connection
is closed from client side, clvmd takes this as an error and
never run restart code.

Ugly hack(TM).

44a82780b9 Use early udev synchronisation and update of dev nodes for clustered mirrors.
When using clustered mirrors, we need device nodes to be created during
processing of device tree, not at its end like we normally do (we need to
access the nodes in cmirror prematurely). Therefore we use a new flag called
"immediate_dev_node" stored in deptree's load_properties struct to instruct the
device tree processing code to immediately synchronize with udev and flush all
stacked node operations so the nodes are prepared for use.

For now, the immediate_dev_node is used for clustered mirrors during
processing the dm_tree_preload_children code only. We can add more later if
needed.

c76681596e daemons/cmirrord/functions.c (part of cmirrord) was referencing
linux/kdev_t.h even though it wasn't needed.  Strangely, it seems
to be causing problems on various architectures (i686) in the
function daemons/cmirrord/functions.c:disk_status_info()->sprintf.

I'm not sure why this is a problem since none of the macros in
kdev_t.h are used in that code, but it certainly doesn't hurt to
pull an unnecessary header and it seems to fix the problem.

c7ec3c65f4 Clean up cluster lock mode and flags definition.
Code is mixing up internal DLM and LVM definitions of lock
modes and flags.

OpenAIS and singlenode locking do not depend on DLM but
code currently cannot be compiled without libdlm.h!

LCK_* flags is LVM abstraction, used through all the code.
Only low-level backend (clvmd-cman etc) should use DLM definitions,
also this code should do all needed conversions.

Because there are two DLM flags used in generic code
(NOQUEUE, CONVERT) we define it similar way like lock modes.
(So all needed binary-compatible flags are on one place in locking.h)

(Further code cleaning still needed, though:-)

9dbad2f74d Add support for dm-mod module autoload.
A kernel patch is on its way for 2.6.35 adding support for dm-mod module
autoload. Udev v155 and higher is able to read static node information given
in modules.devname (extracted by depmod before) and will create such nodes
at its start. The first access to such node will load the module automatically
(directly in kernel) before the actual read/write operation is processed.
