after having configured a kernel with device mapper support, and installed both the libdevmapper and LVM2 tools, when i ran just the command: # pvcreate --version what i got was: /dev/mapper/control: open failed: No such file or directory Is device-mapper driver missing from kernel? /dev/mapper/control: open failed: No such file or directory Is device-mapper driver missing from kernel? Incompatible libdevmapper 1.00.02-ioctl (2003-07-12)(compat) and kernel driver LVM version: 2.00.05 (2003-07-18) Library version: 1.00.02-ioctl (2003-07-12) i was working with the 2.6.0-test1-ac2 version of the kernel, which i'm assuming i didn't need to patch any further since it already had the config options for device mapper and v4 ioctl. did i assume incorrectly? or did i mess up something else? i build device mapper support directly into the kernel. rday _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
