<DIV><FONT face=Arial size=2>Hello,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>My Fedora Core 3 is in its pretty much vanilla
installation form. It utilizes GRUB and LVM, and the installation process
split my 18Gb hd into 3 filesystems:</FONT></DIV><PRE>/boot /boot (100Mb)<BR>/dev/VolGroup00/LogVol00 / ( 16Gb)<BR>/dev/VolGroup00/LogVol01 swap ( 1Gb)</PRE>
<DIV><FONT face=Arial size=2><FONT face="Courier New" size=3></FONT>I want
to:</FONT></DIV><FONT face=Arial size=2>
<OL>
<LI>rename the volume groups and logical volumes to shorter and more
meaningful strings, e.g., vg0, root, swap
<LI>resize (shrink) /boot to 50Mb
<LI>split up / into smaller chunks (root, home, usr, var)</LI></OL>
<DIV>I have a second drive, that has one large logical volume (part of
VolGroup00), capable of holding at any given time all or portions of the
partitions above; there is data in that LV, but there is also unused space left,
which I could use to create a PV, LV, and use it only for this purpose (and yes,
there would be enough space for everything as well). </DIV>
<DIV> </DIV>
<DIV>I just wanted to run this by the group and ask for comments, see if there
is anything specific to worry about, etc. Here is my general plan:
</DIV>
<OL>
<LI>use the FC3 DVD to boot into the system in single user maintenance mode
<LI>rename the existing vol groups and log vols using vgrename and lvrename;
<BR>mount and check integrity; <BR>modify /etc/grub.conf accordingly
<LI>with /boot and the large, second disk partition mounted, copy everything
out from /boot (using, e.g., tar) to the second drive (copy it into a
directory on the existing LV, or create a brand new one?); <BR>unmount;
<BR>resize the partition (using, e.g., parted); <BR>remount; <BR>copy
everything back; <BR>run grub-install --root-directory=/boot /dev/sda1
<LI>now I am left with a 50Mb hole (starting at the end of the new /boot
partition and ending at the beginning of the lvm partition; should I just blow
the lvm away (after copying out the contents of / to my second disk), and
start from scratch with one large PV, or should I add a PV to cover the 50Mb,
then add it to the VG, and then try to somehow incorporate it into one of the
new partitions? <BR>the LV on my second drive is not accessible to parted;
will I have any problem fetching it and adding to VGs if I chose to redo the
whole enchilada from scratch on the first disk? <BR>if I keep things the
way they are, I should be able to use lvresize, lvextend, vgextend, etc,
right?
<LI>with all the data on my second drive, rearrange the LVs to my liking;
<BR>finally copy everything back into the appropriate partitions, and update
/etc/fstab (how? there is a comment in there that it should only be used by
fstab-sync; can it be edited manually as well?); </LI></OL>
<DIV>Thanks in advance for any and all comments! </DIV>
