Alasdair Kergon	d4de7934f8	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

Joe Thornber	3d95cfb367	o Added dev_open and dev_close functions ... o Changed disk-rep to use these o if NDEBUG is not defined the dev_cache will check for open devices on teardown. I was hoping this would speed things up. But I'm still getting: reti:/home/joe/sistina/LVM2/tools# time ./lvm vgchange -a n Volume group vg0 successfully changed real 0m5.751s user 0m0.060s sys 0m0.070s even though I have only 1 device with the vg on it passing the filters.	2001-11-14 10:01:52 +00:00
