Alasdair Kergon	15c325f06a	o Use new LCK_HOLD flag to indicate whether lock should be held on return ... from lock_vol() - otherwise it now attempts to acquire the lock and then immediately releases it. o Extend the id field in struct logical_volume to hold VG uuid + LV uuid for format1. This unique lvid can be used directly when calling lock_vol(). o Add the VG uuid to vgcache to make VG uuid lookups possible. (Another step towards using them instead of VG names internally.)	2002-03-05 20:03:09 +00:00

Joe Thornber	6036e5e0f7	o split the uuid -> device map out from vgcache ... o roll vgcache back to agk's implementation, we'll revisit this as part of the cluster integration. o change the extra_info field in a label to be a void *	2002-01-15 10:24:48 +00:00

Alasdair Kergon	839f595181	Handle orphan PVs too, so hints remain valid after vgreduce.	2001-12-13 15:08:58 +00:00
Alasdair Kergon	faa556e759	Add internal cache holding a 'hint' list of the PVs belonging to each VG. ... A substantial speed-up - particularly in readline mode. If the hints turn out to be wrong, the relevant parts get thrown away. vgscan destroys it totally. In both cases it then rebuilds itself as required.	2001-12-13 00:07:29 +00:00
