I just tried this too. Same result. Anyway, it is 100% replicable here. Can anybody else confirm this? I just did an 1G installation of OpenBSD, then I dd-ed the 1G file (logical block device) to a 100G one. I did all the steps I mentioned above in rescue mode and corrupted the file system. Nikos

Hello, Sorry, what do you mean by mounted file system? The file system was not mounted when I tried to enlarge it. I booted with bsd.rd, mounted the file system just to copy the growfs utility, unmounted the filesystem and then tried to enlarge it. Nikos P.S. This post was sent by 2 mail account
