[CentOS] Cannot remove freshly created logical volumes

Hi, I've got a strange situation where I cannot remove logical volumes even right after they have been created:

[root@centos6 ~]# lvcreate -n c6minimal -L+5G vg_nexus Logical volume "c6minimal" created [root@centos6 ~]# lvremove /dev/vg_nexus/c6minimal Can't remove open logical volume "c6minimal" [root@centos6 ~]# vgck vg_nexus [root@centos6 ~]# dmsetup info -c vg_nexus-c6minimal Name Maj Min Stat Open Targ Event UUID

vg_nexus-c6minimal 253 23 L--w 0 1 0 LVM-rIIS0StztO1tPspxCxiKWJgcmjiufxvXC343e8jObzXGRHbdtvHaHWfh17ZSukm3

I've even gone to runlevel 1 but still LVM claims that the device is open despite dmsetup saying that is not the case. vgck doesn't show anything suspicious either.

Any ideas how I could debug this further?

Regards, Dennis
