Hi. I just stumbled across that LVM nowadays also supports higher RAID levels? Is this "just" reusing the MD code... or is it a new implementation?
reuse
Does using it provide any advantages (i.e. performance) other than using the same userland tools... and perhaps greater flexibility in where the PEs for a RAID come from (which may be pretty arbitrary with LVM, and is always some devices for MD)... not that I'd say that such "flexibility" is really useful.
yep stacking of LVs However some other features available in mdadm are missing in lvm (i.e. array reshape)
Is there any larger documentation available on what happens with the RAID levels and the other segtypes? I couldn't find basically anything... I mean things like mirror/striped are probably clear... but free, error, etc.?
