FreeBSD 9.0 BETA2 gpart resize -s uses whole disk on first resize
Hi gurus, FreeBSD freebsd9.mg8.tmtowtdi.se 9.0-BETA2 FreeBSD 9.0-BETA2 #0: Wed Aug 31 18:07:44 UTC 2011 r...@farrell.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC amd64 When resizing a partition, on first attempt it uses up the whole disk. Only on second attempt it resizes to the correct target size. Resizing from any smaller size to a larger size initially uses up the whole disk, like if -s was not used at all even if it's as little as one logical disk block. I'm wondering if anyone else can reproduce. I just tried to perform the same on an old 8.2-STABLE machine and it did not behave the same. Growing a partition worked fine on initial attempts.
