Saw this while running mirror deactivates: [root@taft-01 ~]# vgremove helter_skelter Do you really want to remove volume group "helter_skelter" containing 1 logical volumes? [y/n]: y Do you really want to remove active logical volume syncd_pri_leg_pri_log_2legs_2logs_1? [y/n]: y Logical volume "syncd_pri_leg_pri_log_2legs_2logs_1" successfully removed Volume group "helter_skelter" successfully removed Internal error: Maps lock 17981440 < unlock 20078592 [root@taft-01 ~]# uname -ar Linux taft-01 2.6.32-203.el6.x86_64 #1 SMP Tue Sep 27 11:36:49 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux I tried to reproduce with a simple program provided by Zdenek (it should reveal the problem in mlock/munlock inconsistency), but it seems to be fine (tried on latest 6.2 kernel 2.6.32-220.2.1.el6.x86_64 as well as the one reported here 2.6.32-198.el6.x86_64). I'm setting cond nak reproducer for now. Created attachment 550667 [details]
Simple test for mlock/munlock
