Re: Salvage files from harddrive
FreeBSD 6.2 didn't use volume labels the same way that 7 and above do; and even then only if you specifically label the filesystems, and even then you can get to the filesystems with the 'bus' methods (which is what you need to do in 6.2 anyway) On your system that you have access to /var in single user mode, note what 'df /var' returns for the device, it will be in the form of: /dev/adXsYL or /dev/daXsYL where X and Y are numbers, and 'L' is a letter. Take note of 'Y' and 'L', but you can ignore 'X'. on the working system note what disks are currently in the system, if you run 'df -l' you'll get a list of everything in the form of above, there make note of 'X' (and ignore 'Y' and 'L'). Now shutdown, move the drive over, and reboot, pay attention to the kernel messages, you should see a new 'adX' line come up that wasn't there on the working system before, this is where your new drive is. (typical layouts are that ad0 is the primary-master, ad1 is the primary-slave, ad2 is the secondary-master, ad3 is the secondary-slave... with sata motherboards ad4 can be the first sata port, ad6 is the next, etc.. these are just generalities to help guide you, pay attention to what the kernel tells you) now that you have that do mount /dev/adXsYL /mnt(take 'X' from the "new" disk on the working system, and YL that you took note of above.).. your old /var will now be on /mnt -- David E.

I've changed the size of the disk slices by copying files over to a nother disk, boot from that one and later back. I would suggest using 'rsync -aHW source dest" And later remove with 'chflags -R noschg source; rm -rf source' -- Alex ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

Personally, I don't think this practise of labelling partitions with names like var makes any sense. fstab exists to keep track of what devices map to which mount points, the point of glabel is to give those devices unique names that are independent of where and when they are detected. I think people get the idea that if they use labels like var they'll never need to edit fstab again. The benefit of that is negligible, it's much easier and less confusing to make minor changes to fstab when you copy it to a new disk than it is to shuffle labels around. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

JK Nay, you need to check as what 'device' that partition has been recognised on your 'new' system and mount it wherever you like e.g. mkdir /tmp/old-var mount /dev/da0s1a /mnt/old-var -- bEsT rEgArDs| "Confidence is what you have before you tomasz dereszynski | understand the problem." -- Woody Allen | Spes confisa Deo| "In theory, theory and practice are much numquam confusa recedit | the same.

If you can mount this disk in single user mode your best bet to be safe is
just glabel it to something else that your second system is not before you
take the disk out of the machine.
Even though I don't think it should/would be a problem I can not speak of a
authoritative nature on this subject because I have not had to test such
cases.
Best regards.

It shouldn't be a problem. If you stick the "broken" drive in a new
system it will show up as a new device to the 2nd system.
You will then manually mount the 1st system via the device node to
wherever you want. It will not auto-mount that to /var .
So, for example your 2nd system has /dev/ad4s1 as its main disk.
When you plig the 2nd disk (from the old box) it will show up as
/dev/ad5s1 or similar. YOu would then just mount the /var/ slice to
wherever you want.
For example:
mount /dev/ad5sa6 /mnt/oldvar
or similar. Please note that your device nodes and slice numbers
will most likely be different.
Henrik
I think (correct me if I am wrong) he is trying to describe that glabel is
being used on both systems and that he is worried that a label of "var"
that would be in /dev/ufs/var on two separate disks would be conflicting
and which one would be mounted first as he does not wish for the disk he
is trying to save the contents of to be mounted and be used as the var of
the system he is placing the said disk he wants to recover.
