I have an EC2 Instance(EBS Backed-root partition) with EBS volumes configured via LVM.
I have formatted it as ext4 and can mount it to store data etc.
Now i want take a snapshot of the root partition, hence in that case i go and detach the other non-root EBS volumes (configured in LVM).
Here a regular detach does not work, and i have "force" detach almost always.
Although, i another similar setup with RAID instead of LVM and there after stopping RAID, i can easily detach.
The whole setup is running Ubuntu Maverick 10.10
Please assist me in the same.

It sounds like you need to disable the volume group with
vgchange -a n vgname
before you call the EBS detach API
