    I have a few a5200 disk arrays, striped and mirrored, but each disk array
    has 10 volumes. Since vxprint is extremely ugly and cumbersome to look at,
    I figured that I want to combine some of the adjacent volumes into one
    (more precisely, to ditch current volumes, and rebuild them with bigger
    subdisks).

    I was wondering if there are any disadvantages of doing that.

    One thing I kind of thought of, is that with smaller volumes you have more
    control over which part of the disk you're using (e.g. outer sectors are
    supposedly faster). But I never was able to determine where VM starts
    counting when building subdisks.

    Additionally, after a crash, bigger volume would take longer to sync up,
    which would be especially bad if volume has barely any data in it. (as
    opposed to a nearly full volume, which only uses a smaller part of the
    disk).

    But for disk arrays nearly full, this would really ease administration.

    Thoughts?

    Thanks, will summurize.
