Hmm, while I can understand motivation IMHO it's better for a user to 'convert' to lvm2 - it might not obvious on the first sight but in fact you would need to provide 'stacked' device from 'boot' moment. IMHO we could probably make it more easier is to add capability to switch any device into lvm2 device - there is in fact lot's of 'hidden' code in lvm2 to actually support this - but it's awkward to use. While there could be some 'use' for 'unused' devices - so before the use the user can use 'linear' mapping instead of real device, but there are still lots of 'security' issue connected to this - so IMHO such solution could be only seen as a temporary hack to do things in quick but highly unsecure way. lvm2 would be a separate request - outside the scope of this bugzilla *** Bug 1286283 has been marked as a duplicate of this bug. *** Moving feature request from RHEL to upstream. Added dmstats subcomponent Might be clearer to start by providing a command that just wraps a linear mapping around a given device, subject to certain conditions. We might also be able to build this into the boot process as a substitute for the original device. |
