I ran fsck on my filesystems while system was running (partitons were mounted rw with moderate FS usage). fsck reported there were errors (INCORRECT BLOCK COUNT and others). I decided to reboot to single mode and check all filesystems. But in single mode fsck did not find any errors. 1. Can I be sure my filesystem is consistent? 2. If fsck reports nonexistent errors (and probably will try to fix them if asked), isn't it even danger to run fsck on running system? 3. How can I check (not fix) filesystems while partitions are mouted rw and are under usage? FreeBSD 7.3/kernel, 7.2/world. Thanks in advance. -- // cronfy
