My questions for any filesystem experts are:
Is there a way to adjust the existing md partitions to get the right alignment for 4k sectors without having to do a file-oriented copy to new partitions? A resize + a dd copy to shift the position might be feasible time-wise if that would work.

We have some non-conformant units, and after seaching, concluded that a 'wipe and rebuild' was the most time efficient process for us -- YMMV
Is it worth converting to ext4?
ext4 is pleasant in some large filesystem cases, but probably overkill as a blanket option.

If I start over from scratch with 6.x, will the partitioning tools automatically align for 4k sector drives (with/without lvm?)?
no idea if gparted does this by default -- it does not in all versions; certainly fdisk did not -- 4k alignment is on our deployment checklist, and we are manually checking partitioning to make sure, when we are rebuilding boxes
<snip> <rant> I think it was when I was building a 6.0 box a couple weeks ago, but I'd partition, it would do an mkfs... and *then* tell me it wasn't aligned, and I played with it several times, and it absolutely would NOT align it, nor offer to do so.
