Guys, It's been at least a couple of years now that I've had the following setup on my main machine, a Debian machine which is heavily upgraded all the time, and runs fairly bleeding edge kernels. Basically, I have a pair of 120gb disks. They're partitioned, each with just one large partition. These two partitions are then mirrored into a single RAID1 device called md0. On top of that I have LVM2 running, which makes md0 into a pv, which holds a vg called 'data_vg', which holds a pair of partitions called 'local_lv' and 'home_lv'. They are then mounted as /home and /local. Works well. To summarize: disk -> partition -> md -> pv -> vg -> lv -> fs -> mount point But I'm wondering if I'm being a) too complex here or b) inverted in how I want this setup so the LVM is under MD, or c) just fine overall. Should I be using LVM2 to build my RAID1 devices directly? Should I be using MD instead to build my resizeable volumes to hold my filesystems? When I first set this up, MD was pretty new, as was LVM and there was no really easy way to do what I wanted, which was to setup mirrored volumes which I could re-size at needed. Not that I resize them often since they're ext3. And no, I don't want reiserfs3, xfs, or any other filesystem on there. I don't trust them. Basically, I'm looking for reliabilty of my data, and then speed. My next goals are to: 1. setup MD bitmaps for speedier recoveries 2. mirror my /, swap and /boot partitions for reliability - requires mkinitrd to work well and easily for new kernels. - requires I don't screw up my current setup when I try this.
