Is there any way to prevent any automatic LV activation/deactivation? And have full manual control via lvm_lv_deactivate/lvm_lv_activate? Setting activation = 0 in global section of lvm.conf did not do the job, because then lvm_vg_create_lv_linear fails, so I even cannot create a LV. Thanks, Alex. <div><div></div><div class="h5"> On Tue, Jul 19, 2011 at 5:14 PM, Alexander Lyakas <<a href="mailto:alex.bolshoy@gmail.com">alex.bolshoy@gmail.com</a>> wrote: > > Hello everybody, > I am using stock ubuntu natty with lvmlib 2.02.66: > root@11:/mnt/work/alex# uname -a > Linux 11 2.6.38-8-server #42-Ubuntu SMP Mon Apr 11 03:49:04 UTC 2011 > x86_64 x86_64 x86_64 GNU/Linux > > In my code I open a VG, iterate over all the LVs and then call > lvm_lv_deactivate() on each LV.
