lost files/dirs without reboot

[Thomas Klausner <tk%giga.or.at@localhost>]

Hi!

On a WAPBL-enabled root file system on 7.99.3/amd64, I have checkouts
of various repositories, including the NetBSD ones.

I have a script to update those, basically just a collection of 'cd
somewhere && cvs up'.

Today it failed, because one repository had lost its main CVS
directory and one had disappeared completely. Another repository also
disappeared completely.

At the time, the machine had an uptime of 16d.

How can this happen?


I then rebooted to run a manual fsck and booted into single user mode,
because I remember being able to fsck even the root file system there
(do I misremember?). However, root is now on a wedge, and 'fsck
/dev/dk2' told me the device was busy. Is there a way to check the
root file system without booting from a different disk?


And the easiest question last: What's the cvs root for wikisrc?

Thanks,
 Thomas
