[Moosefs-users] mmap file on moosefs error

[youngcow <you...@gm...>]

Hi,
  I found a error when I used moosefs. I used openvz(container-based
virtualization for Linux) on RHEL 5.6 x86_64
and put all container file into moosefs and I notice an error when I was
running "rpm -qa " in vm:

	rpmdb: mmap: No such device
	error: db4 error(19) from dbenv->open: No such device
	error: cannot open Packages index using db3 - No such device (19)
	error: cannot open Packages database in /var/lib/rpm

So I tested it in physical machine:
I put the directory "/var/lib/rpm" into moosefs, link the dir to
/var/lib and run "rpm -qa",the error message also:
	rpmdb: mmap: No such device
	error: db4 error(19) from dbenv->open: No such device
	error: cannot open Packages index using db3 - No such device
	error: cannot open Packages database in /var/lib/rpm

Anyone knows the reason. Is it a bug of moosefs?

Thanks.
