Just discovered that on CentOS 4.1 when you issue the command:
lvcreate -s -n temp -L2G /dev/vgname/lvname
to create a snapshot, you get the error message:
snapshot: Required device-mapper target(s) not detected in your kernel
I've checked and recheck my spelling and tried using the device created under /dev/mapper. I've tried it on both x86_64 and on i386. Works as expected under CentOS 3.5.
Any ideas what is going on?
