Use lvconvert --repair in dmeventd mirror DSO.
for now.

It replaces bad behaviour in one set of circumstances with bad behaviour
in a different set.  We think the behaviour needs to be more configurable.

49b9da5a56 Fix readahead test. 2009-05-20 11:27:14 +00:00

d396100278 Use readahead of underlying device and not default (smaller) one.
When we are stacking LV over device, which has for some reason
increased read_ahead (e.g. MD RAID), the read_ahead hint
for libdevmapper is wrong (it is zero).

If the calculated read_ahead hint is zero, patch uses read_ahead of underlying device
(if first segment is PV) when setting DM_READ_AHEAD_MINIMUM_FLAG.

Because we are using dev-cache, it also store this value to cache for future use
(if several LVs are over one PV, BLKRAGET is called only once for underlying device.)

This should fix all the reamining problems with readahead mismatch reported
for DM over MD configurations (and similar cases).

a01e55b6ec Use lock query instead of activate_lv_excl
- switch lvremove to not force activate volume when removing
 - ditto for force resync

 - fix some wrong return codes in lvchange_resync()

eb91c4eee3 Use suspend with flush when device size was changed during table preload.
This allows online mirror resize, also removes condition to preventing
code to do this.

fa6dca9f28 Add infrastructure for queriying for remote locks.
Current code, when need to ensure that volume is not
active on remote node, it need to try to exclusive
activate volume.

Patch adds simple clvmd command which queries all nodes
for lock for given resource.

The lock type is returned in reply in text.

(But code currently uses CR and EX modes only.)

8dd0ae923b Fix lvconvert check for multiple-segment mirrors (mornfall) 2009-05-19 10:27:47 +00:00

ac0034c20f Use lvconvert --repair in dmeventd DSO (mornfall)
This means two things:

1) Non-mirrored LVs will be no longer affected by mirror monitoring. (Before,
if you had a LV that went partially missing on a VG where a mirror leg failed,
this LV would be removed automatically by dmeventd... Probably not an
unrecoverable dataloss bug, but still quite unpleasant.)

2) If enough parallel PV space is available at the time of the mirror failure,
the failed devices will be automatically replaced using this spare space. Which
(and whether) free space may be used is still not configurable, but is a
planned feature. Since it is relatively easy to undo the action by converting
the mirror manually, I don't consider this to be a showstopper. In fact, I
think the compromise is much better than what we have now.

65edd11bfb If pvmove fails activating mirror volume, try restore to previous state.
pvmove now keep suspended devices if temporary mirror creation fails.

We can try to restore previous state if it is first attempt to activate
pvmove (code basically run the same code as --abort automatically).

e1b0dce76e Use PV UUID in hash for device name when exporting metadata.
Currently code uses pv_dev_name() for hash when getting internal
"pvX" name.

This produce corrupted metadata if PVs are missing, pv->dev
is NULL and all these missing devices returns one name
(using "unknown device" for all missing devices as hash key).

970f241c52 Check max_lv on only place and force the check only for new volume.
We can temporarily violate max_lv during mirror conversion etc.

(If the operation fails, orphan mirror images are visible to administrator
for manual remove for example. Not that this should ever happen:-)

Force limit only for lvcreate (and vg merge) command.

Patch also adds simple max_lv tests into testsuite

afd9ba98c1 Merge lv_is_displayable and lv_is_visible.
Displayable and visible is the same thing.

volumes_count(vg) is now vg_visible_lvs() and always
returns number of LVs from user perspective.

59d8429cb3 Introduce lv_set_visible & lv_set_invisible and use lv_is_visible always.
The vg->lv_count parameter now includes always number of visible
logical volumes.

Note that virtual snapshot volume (snapshotX) is never visible,
but it is stored in metadata with visible flag.

0b706ac672 Introduce link_lv_to_vg and unlink_lv_from_vg functions.
link_lv_to_vg and unlink_lv_from_vg are the only functions
for adding/removing logical volume from volume group.

Only these function should manipulate with vg->lvs list.

494b4cec7b Tidy format1 import LV function.
Later patch initializes lv->vg after the LV structure is prepared,
so pass through cmd context and do not use vg->cmd here.
Also move LV id calculation (which uses lv->vg too).

Also properly free memory pool if operation fails.

d60f341d96 Remove vg->lv_count and use counter function.
This should not cause problems but simplifies code a lot.

(the volumes_count is merged and renamed with lvs_visible
function by following patch.)

4b13d5a823 Fix snapshot segment import to not use duplicate segments & replace.
The snapshot segment (snapshotX) is created twice
during the text metadata segment processing.

This can cause temporary violation of max_lv count.

Simplify the code, snapshot segment is properly initialized
in init_snapshot_seg function now and do not need to be replaced
by vg_add_snapshot call.

The vg_add_snapshot() is now usefull only for adding new
snapshot and it shares the same initialization function.

The snapshot name is always generated, name paramater can be
removed from function call.

5a820745ce Remove NON_BLOCKING lock flag from tools and set a policy to auto-set.
As a simplification to the tools and further liblvm, this patch pushes
the setting of NON_BLOCKING lock flag inside the lock_vol() call.
The policy we set is if any existing VGs are currently locked, we
set the NON_BLOCKING flag.

Should be no functional change.

920e68d603 Fix first_seg() call for empty segment list.
The seg variable is temporary variable for list iterator,
code cannot expect that after iteration it remains NULL
(it contains non-NULL pointer here id list is empty).

Patch fixes first_seg function so it now correctly returns NULL
for empty segment list.

0b502933c5 Introduce lvm2_install target.
Buildsystem support device-mapper only install,
but generic install tagret includes both dm+lvm2.

For distribution which uses separate install_device-mapper,
there is no way how to install lvm2 only
(so after installing lvm2 for packaging purposes
built system must remove installed device-mapper files).

Fix it by allowing lvm2_install target, similarily like
install_cluster for clvmd.

(install = install_device-mapper + install_lvm2)

be82186cba Do not use generic install if running install_device-mapper.
