Further to the problems I reported yesterday
- panic : vinvalbuf: dirty bufs
- fixit floppy

I couldn't work out what to do in fixit, so I installed 3.4 on
another disk, which is now up and running, so I can forget
about the fixit floppy problem.

I've now put the old disk in as a 'slave' and when I boot it
recognises the disk as /dev/wdc1

What I want to do is try and mount my old /usr partition
and hopefully recover some files.

I was hoping to do something like

mount /dev/wd1s1f /mnt

but /dev/wd1s1f does not exist

I guess I need to do 'newfs' or something similar, but
the man page is a little cryptic.

Can anyone point me in direction of a tutorial style document ?

Thanks in advance
Dave

Hi,
Still trying to get to bottom of 'panic: vinvalbuf: dirty bufs'
problem described below.

I've now booted the fixit floppy

Could someone advise me how to check that certain files
still exist on the hard disk.

I guess I need to mount my /usr partition as /mnt

/usr was /dev/wd0s1f

on fixit floppy I have /dev/wd0s1 & /dev/rwd0s1

Can I mount the /usr partition ???

Assuming I can,  and that I find the files I'm particularly keen
not to lose, can I get them off ,  to floppy or by ftp ?
They are modest sized source files.

I've not been able to find any documentation on using fixit.
Could someone point me in right direction.

Thanks in advance
Dave

Hi,
Is anyone familiar with the error message

panic: vinvalbuf: dirty bufs

I've looked through archives, and seen similar messages during
installation, or creating new filesystems, but I'm getting it
on a system that's been working fine for some time.

AMD-K6(tm)-2/450
256 MB RAM
FUJITSU MPD3173AT
FreeBSD 3.3

Suddenly last week I started getting system crashes and had to
run FSCK manually a couple of times.

I then noticed the following error occuring at regular intervals.

soft  error writing fsbn

the system has now crashed and now will not boot.

Changing root device to wd0s1a

Clearly anyone knowing the exact solution would be most welcome.
However interpretation of the error messages to give a best guess on the following would be a start.

Is this a disk hardware problem ?
Is it configuration problem ?
Are contents of disk corrupt ?
Could this be anything to do with large filesystems ?

It's a 17GB disk, and I've recently added new data taking the /usr
partition up to about 65% full.

Any advice would be welcome, Thanks in Advance
Dave
