Be careful not to waste your time on some thing that will not be included.... I see the order of events like this: 1) Generic layering of LVs 2) Improved mirror DSO 3) Mirrored log implementation Note that once you get #1 done you /should/ be able to get a mirrored log by: prompt> lvcreate -m1 --mirrorlog core -l 1 -n mirrored_log vg prompt> lvcreate -m1 -L 5G -n mirror vg /dev/sdb /dev/sdc /dev/vg/mirrored_log Leapfrogging #2 /might/ be acceptable, but leapfrogging #1 is not. This is because you are creating a one-off solution rather than creating something more general that would benefit LVM as a whole. Feel free to disagree, but I really see the above as the way forward. brassow On Dec 29, 2008, at 6:10 PM, malahal@xxxxxxxxxx wrote: This patch adds '--mirroredlog' option to LVM commands to create a |
