First, let me give thanks to all who gave me answers on my xcdroast issue.
This time I don't have a problem, more of a situation.
I currently run FC4 with 2-disk drives, a 80-gig and a 15-gig. I caught
a great deal on a 300-gig drive and I want to swap out the 15-gig for
the 300-gig. What's on the 15-gig scares me a little:
/dev/hdc1 4031 1m blks /u03 - user data and database files
/dev/hdc2 4031 1m blks /u02 - user data and database files
/dev/hdc3 2023 1m blks swap
/dev/hdc5 2023 1m blks /u04 - user data and database files
/dev/hdc6 478 1m blks /opt
/dev/hdc7 1490 1m blks /var
/dev/hdc4 standard extended partition
boundary that covers hdc5, hdc6, and hdc7
Is there a way to do this without having to reinstall FC4? Where can I
find the documentation? Any thoughts would be appreciated.
Sure. First, install the disk as /dev/hdd, the secondary (slave) drive
on the 2nd cable, s/b the middle plug. Do this while powered down, and
reboot.
Then run 'fdisk /dev/hdd', and assign, but do not label, a set of
partitions to match the above but with sufficiently different names that
you can readily identify which partition (/dev/hdd7) is var2, and
establish those in the /etc/fstab file using these names. Size them
roughly in proportion to the /dev/hdc versions but scaled up (except for
the swap and /var2, which need be no bigger than a gig for swap, and
maybe 2 gigs for the second var2), using the space basicly to expand the
user partitions. Exit fdisk with a w, and rerun it to verify the table,
then quit it again. Then do the mke2fs on those partitions where its
suitable, and a mkswap on the new /swap.
Now make new /mnt/hdd/$newnames entries to match the ones you added in
/etc/fstab. Mount each of them to /dev/hdd/$newname, and concoct an
rsync command line to copy each of the existing /dev/hdc partitions to
the new ones on /mnt/hdd/$newname. I think, but don't take it as
gospel, that rsync -avc /src/path /dest/path is a good starting point.
This will take a while, and the users should be off-duty/locked out by
some means while this is taking place.
Now, before the data changes in /var by more activity, edit /etc/fstab
to remove the extra hdd entries with a comment, power down, remove hdc,
and change hdd to be the master drive and on the end of the cable,
effectively it will become /dev/hdc. When you power back up, it should
just be there.
