@mechy: this is what your personal experience is, while mine is different. they are both of equal value. whereever i discussed the matter with people that claimed sfs to be perfect, they mostly turned out to be mos users, as if it was selfexplanatory. thats why i ask.
now, a test case proves something till it fails. in your case it havnt yet, in my - multiple times. take into account it is not enough to use your system 24/7, and stick different expansions into it to prove this point. my rack remains pretty unchanged all the time. writing and reading the drives a lot may trigger the bug more likely. note that i dont want to opress anybody not to use sfs, just to warn to use a filesystem that seems more secure atm.
