* Replace free_vg with release_vgZdenek Kabelac2011-08-101-6/+6
| | | | | | | | Move the free_vg() to vg.c and replace free_vg with release_vg and make the _free_vg internal. Patch is needed for sharing VG in vginfo cache so the release_vg function name is a better fit here.
* Fix free_vg orderZdenek Kabelac2011-03-301-7/+7
| | | | | | | | | | | | | | As now the FID management is more complex, the code inside free_vg needs to access some parts of memory pools which were not needed before. For this - makes the order of unlock_and_free_vg() unconditional. Keek using unlock_and_free_vg() API function. For properly working VG locking mechanism only the alphabeting locking orderer needs to be preserved. TODO: there could be few more code parts simplified when we 'officially' support of referencies between different memory pools.
* Const fixingZdenek Kabelac2011-02-181-1/+1
| | | | | | | | | | | | | | | | Fixing some const warnings - with API change in: int vg_extend(struct volume_group *vg, int pv_count, const char *const *pv_names, Change is needed - as lvm2api expects const behaviour here. So vg_extend() is doing local strdup for unescaping. skip_dev_dir return const char* from const char* vg_name. Rest of the patch is cleanup of related warnings. Also using dm_report_filed_string() API change to simplify casting in _string_disp and _lvname_disp.

* Update _vgmerge_single() to move fid->metadata_areas_ignored.Dave Wysochanski2010-06-281-0/+6
| | | | | | | | | | | | | When vgmerge is called we move the mdas from the source to the destination. With metadata balancing we now have another mda list, fid->metadata_areas_ignored, so move the mdas on this list as well. This patch should not matter as the code is written today. However we include it for completeness in the case that _vgmerge_single() is refactored and/or moved into a library function. Signed-off-by: Dave Wysochanski <dwysocha@redhat.com>
* Rename fid->metadata_areas to fid->metadata_areas_in_use.Dave Wysochanski2010-06-281-3/+3
| | | | | Rename the metadata_areas list to an 'in_use' list to prepare for future 'ignored' list.
* Call add_pvl_to_vgs() and del_pvl_from_vgs() from more places.Dave Wysochanski2010-04-131-9/+5
| | | | | | | Now that we have library functions to add/delete a pv from the vg->pvs list, call them from everywhere. Signed-off-by: Dave Wysochanski <dwysocha@redhat.com>
* Add lots of missing stack debug messages to tools.Alasdair Kergon2009-09-141-2/+8
| | | | | Make readonly locking available as locking type 4. Fix readonly locking to permit writeable global locks (for vgscan). (2.02.49)
* Change vgmerge behavior to open/lock first vg based on alphabetical ordering.Dave Wysochanski2009-09-021-7/+21
| | | | | | | This enforces our alphabetical lock ordering rules for vgmerge. Author: Dave Wysochanski <dwysocha@redhat.com>
* Refactor vgmerge - combine _vgmerge_to and _vgmerge_from into _vgmerge_vg_read.Dave Wysochanski2009-09-021-24/+10
| | | | | | | These functions are identical so should be no functional change. Author: Dave Wysochanski <dwysocha@redhat.com>
* Refactor vgmerge - create _vgmerge_from and _vgmerge_to.Dave Wysochanski2009-09-021-9/+31
| | | | | | | | | | These functions are really identical but for clarity I made them separate functions in this patch. Should be no functional change. Author: Dave Wysochanski <dwysocha@redhat.com>

* Remove unneeded LOCK_NONBLOCKING from vg_read() API.Dave Wysochanski2009-07-081-2/+1
| | | | | | | | | | | | | | | | | | | | | | | Remove unneeded LOCK_NONBLOCKING from vg_read() API and tools that use it. We no longer need this flag anywhere since we now automatically set LCK_NONBLOCK inside lock_vol() if vgs_locked(). For further details, see: commit d52b3fd3fe2006e2d13e42f8518b6512bff03710 Author: Dave Wysochanski <dwysocha@redhat.com> Date: Wed May 13 13:02:52 2009 +0000 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. At some point it may make sense to add this flag back if we get an RFE from a liblvm user, but for now let's keep it as simple as possible. Signed-off-by: Dave Wysochanski <dwysocha@redhat.com>
* Fix vg_read() error paths to properly release upon vg_read_error().Dave Wysochanski2009-07-071-2/+5
| | | | | | | | | | | | | | | | | | | | | | | Fix vg_read() error paths to properly release upon vg_read_error(). Note that in the iterator paths (process_each_*()), we release inside the iterator so no individual cleanup is needed. However there are a number of other places we missed the cleanup. Proper cleanup when vg_read_error() is true should be calling vg_release(vg), since there should be no locks held if we get an error (except in certain special cases, which IMO we should work to remove from the code). Unfortunately the testsuite is unable to detect these types of memory leaks. Most of them can be easily seen if you try an operation (e.g. lvcreate) with a volume group that does not exist. Error message looks like this: Volume group "vg2" not found You have a memory leak (not released memory pool): [0x1975eb8] You have a memory leak (not released memory pool): [0x1975eb8] Author: Dave Wysochanski <dwysocha@redhat.com>
