Zdenek Kabelac	96279ac1c0	Make detach_pool_message visible for tools ... Move there also vg_write and vg_commit.	2011-10-30 22:01:39 +00:00
Zdenek Kabelac	f8d46bd256	Thin cleanups ... Fix/cleanup several error messages. Remove test for seg_is_thin which could never be true there. Replace (1<<24) with predefined constant.	2011-10-30 22:00:57 +00:00
Zdenek Kabelac	0968dfcd03	Thin support for stripe ... Support stripe options to create thin data pool LV. TODO: combine chunk size and stripe size.	2011-10-28 20:32:54 +00:00
Zdenek Kabelac	f4c77bd0e3	Recoded way to insert thin pool into vg ... Code in _lv_insert_empty_sublvs was not able to provide proper initialization order for thin pool LV. New function extend_pool() first adds metadata segment to pool LV which is still visible. Such LV is activate and cleared. Then new meta LV is created and metadata segments are moved there. Now the preallocated pool data segment is attached to the pool LV and layer _tpool is created. Finaly segment is marked as thin_pool.	2011-10-22 16:44:23 +00:00
Zdenek Kabelac	759b9592ba	Update error message ... Drop INTERNAL_ERROR from public API functions. Improve some messages.	2011-10-19 16:42:14 +00:00
Zdenek Kabelac	8de912b677	Simple validation of messages in mda ... Check we do not combine multiple messages for same LV target and switch to use 'delete_id' to make it clear for what this device_id is being used.	2011-10-19 16:39:09 +00:00
Zdenek Kabelac	3dcce042f6	Drop messages referencing deleted LV ... lvremove may remove problematic LV for thin target.	2011-10-19 16:37:30 +00:00
Zdenek Kabelac	97d0f72c92	Just indent changes ... Some tabs & spaces.	2011-10-19 16:36:39 +00:00
Zdenek Kabelac	b04e977851	Remove test for thin_pool ... Since both functions are called during mda read - we don't have full LV info at this moment.	2011-10-19 16:32:34 +00:00
Zdenek Kabelac	a25434a3a3	Message support for thin provisiong ... lvm part of messaging. Each message is now stored it's own thin pool section: message1 { create = lv } Messages are queued to thin pool dm target when this target is going to be resumed or used through some dependency. Currently 'delete' message are purely queued and processed with next thin pool resume operation (i.e. create_thin). WARNING - thin provisioning support is developmental code.	2011-10-17 14:17:09 +00:00
