No. Softupdates is a method of improving performance by optimizing writes to the disk ... has no real relation to the space involved. is there any way with 5.2.1 to move around disc space between partitions "on the fly" ? Definately not "on the fly". well, that's why i left it in quotes. "on the fly" as opposed to reinstalling/ rebuilding partitions. i don't want to have to do a newfw(8) on the partitions and have to try and get all the data back ... i can re-edit partition tables, but i'm not 100% familiar with doing it command-line ( read: not from sysinstall at install time ) so i'd rather not risk goofing the data ... IMHO, the best way to avoid/deal with this problem is to do the following the next time you install: 1) Make the entire disk one big Vinum partition 2) Make Vinum subdisks for the different partitions you want. Size them accordingly, and _leave_any_unneeded_space_unused_! 3) Later if you find you messed up, Vinum gives you the power to join unused space to an existing subdisk, and you can then use growfs to increase the filesystem size. Hell, you can even add new disks if you fill up the entire disk! never used Vinum. seen it mentioned a lot, but never read up on it because i wasn't sure what it was ... guess it's time to do some reading, eh? thanks, -b-- References 1. mailto:geektron@comradeburnout.com
