> >http://serverfault.com/questions/500533/lvm-mirror-with-data-and-logs-mirrored-on-same-2-devices wow, that smells like a logic bug to me. If not, then the documentation needs a VERY obvious warning about how to properly do mirrored devices with mirrored logs (nee 4+ distinct PV devices). If the internals can't be fixed, then it needs to error out on creation when there aren't 4 devices to work with. Any particular reason why you wanted pseudo-external logs in the first place? Does 'lvcreate -nv' show you the work plan? I'd say most people use MD for any sort of RAID functionality. It's implemented better (or at least faster). >I've just started with LVM, I might not see the obvious. maybe turn down the exotic, till you have more experience? _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
