David, do you use something which can be considered > non-standard, like snapshots? > I had been renaming the name of the mirror and the root mount point in an effort to keep the explanations shorter and less confusing, but I won't do that any more. The / partition is actually on "f" not "a", and the mirror is called "gmroots1" not gm0s1. Something that might be of interest, from the output of mount (snipped for brevity): # mount /dev/mirror/gmroots1f on / (ufs, local, read-only, soft-updates) devfs on /dev (devfs, local) Yes, soft-updates are on for /, but I've seen this problem (same partition, same error code) when they have not been on. # bsdlabel /dev/mirror/gmroots1 # /dev/mirror/gmroots1: 8 partitions: # size offset fstype [fsize bsize bps/cpg] a: 80325 0 4.2BSD 2048 16384 5024 b: 4194304 80325 swap c: 74231135 0 unused 0 0 # "raw" part, don't edit d: 55738981 8483659 4.2BSD 2048 16384 28552 e: 10008495 64222640 4.2BSD 2048 16384 28552 f: 4209030 4274629 4.2BSD 2048 16384 28552 Regards, Dave -- Software Engineer Secure and Mobile Connectivity Nokia Enterprise Solutions +61 7 5553 8307 (office) +61 412 728 222 (cell)
