[Gllug] Moving System to a new Disk - checking out my plan...

[Ken Smith]

Hi Guys, I have an FC6 system (MythTV) where hda=60G and hdb=250G. hdc 
has a dvd drive on it.

Smartd, and a couple of system lockups, tell me that hda is on its way 
out. /boot is on hda. The rest of the system uses LVM and there were 
some LV's in a VG that was spread over hda and hdb. Interestingly LVM 
had put most of the data on the hdb area anyway.

I've now shrunk one of the LV's (and, first, the ext3 filesystem in it!) 
and shrunk the VG so it is now only on hdb. So hda now only holds /boot

I have a 300G drive, to replace hda, currently connected via USB as sda. 
I have created swap and /boot partitions & filesystems on it and 
tar/untar'd the content of /boot over to it.

So my plan is....

- Shutdown, take the 60G hda out and install the 300G in its place, boot 
with FC6 rescue system.
- label the new boot partition as /boot and check in fdisk that its set 
bootable.
- reinstall grub.
- reboot into fc6 from hda. (I hope)
- extend the VG into the new space in hda and stretch the LV's and file 
systems as required.

Smile - So what am I missing? This should work - shouldn't it.

In order to do some testing of new s/w releases, without risking the 
'production' system, I have also created a 15G partition on the new hda. 
My plan is to tar/untar or rsync the current system (/boot and 
everything else) into that partition. (Less the huge .mpg files, the 
rest of it is only 4.5G. The test system doesn't need to be a big LVM 
setup, just enough to test out new kernels and especially capture 
drivers.) Then label the test ext3 partition as /test, edit its fstab 
and grub.conf accordingly to allow it to boot. What have I missed there???

Thanks in advance

Ken
