Hello I experienced some nasty FFS corrupton, which was only resolved by reformatting.L
The filesystem was a root partition image for a Xen NetBSD-7.1/i386 domU. It was formatetd FFSv1 level 4. Everything was fine until I scp it over the network on a new machine. After this migration, the filesystem started corrupting the same file /usr/pkg/etc/httpd/httpd.conf at the same time, which happens to be /etc/daily end of execution. Other files were affected, ncluding a /usr/pkg/etc/httpd/httpd.conf.bak set there to recover, but it is difficult to asset the span of the problem. I assume few files were touched because the machine could still work after just restoring httpd.conf httpd.conf metadata did not change, its content was just filed with some fixed length binary records (sample included below, in case it rings a bell to someone). Setting immutable flags did not prevent the corruption; And using ktrace on /etc/daily showed it did not touch httpd.conf nor even its parent directory. And fsck did not fid anything wrong. Is there anything ringing a bell to someone here? Any explanation?
