Summary: How do I run reiserfsck on / ?

I have previously succesfully run e2fsck on / while logged in through ssh.
e2fsck is happy as long as / is mounted read only. Reiserfs, however,
seems to be a bit more picky.

I can run reiserfsck --check:

  There were found 175 corruptions which can be fixed with --fix-fixable

but not --fix-fixable:

reiserfsprogs 3.6.2

Will check consistency of the filesystem on /dev/hdb2
Will fix what can be fixed w/o --rebuild-tree
Will put log info to 'stdout'

Do you want to run this program?[N/Yes] (note need to type Yes):Yes

reiserfsck --fix-fixable started at Wed Sep 25 15:12:04 2002
###########
Filesystem seems mounted read-only. Skipping journal replay..
--fix-fixable ignored

So how do I correct the errors on / through ssh? I am willing to sacrify
all files made after last reboot, so I guess the journal is not important
to me.

Summary answer: Boot off rescue disk and run reiserfsck.

The only supported way is to boot off separate boot device (be it another
partition on same drive, floppy or CD).

There are unsupported ways of course, but doing so you are voiding our
warranty ;).
