Extending to 10.91? But it was at 10.91! 3.15G is not significant compared to 10.91TB. You know the saying, "A billion here and a billion there, and pretty soon you're talking about real storage." > So why does parted show a 12TB disk while lvm shows only a 10.91T > disk and why did lvm show 3.15G free when it wasn't really there? 12.0 TeraBytes (12*10^12) ~= 10.91 TibiBytes (10.91*2^40) to 4 decimals. The 3.15G was there, you added it to your LV (but you still need to resize the filesystem). 10.91*2^40 + 3.15*2^30 ~= 10.91*2^40 to 4 decimals. > How do I get my 1.09T back from lvm? That seems like awfully > high for an overhead number for lvm. I'd expect more like "0.09T". http://www.innumeracy.com/ -- Stuart D. Gathman <stuart@bmsi.com> Business Management Systems Inc.
