Hi there…
I’ve been reading through various docs but getting a bit lost – figure this
must be fairly easy to explain ;)
On my machine (Dell R710 Poweredge) I have 6 SAS drives running RAID5 via
Perc 6/I controller. To get Fedora 10 to install, I had to shrink the
initial partition down so I thought I’d install with just this:
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda2 10079084 1354216 8212868 15% /
/dev/sda1 198337 19162 168935 11% /boot
tmpfs 4149532 0 4149532 0% /dev/shm
Then I’ll take the remaining 4.8TB or so and mount them after installing.
The install went fine now with the smaller partition to boot with….
So, having not run Fedora for a bit, I thought I’d fire up FDISK but it
tells me:
WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk
doesn't support GPT. Use GNU Parted.
So I fire up parted and create a partition (weird that it only supports
ext2 vs ext3). That part seems to go fine and now I need to add that
partition to /etc/fstab but now I get confused:
I thought that was a little weird so I looked it up, and you're correct,
parted does not support ext3 directly, however, the easiest thing to do is
create the partition in parted but format it from a regular shell i.e. "mkfs
-t ext3 /dev/sdX".
UUID=8e37b3d8-a52f-4620-ad58-1ae79abd8b50 / ext3
defaults 1 1
UUID=74dfbed0-e91c-4d95-b09c-0b8eb9d96543 /boot ext3
defaults 1 2
tmpfs /dev/shm tmpfs defaults 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
sysfs /sys sysfs defaults 0 0
proc /proc proc defaults 0 0
UUID=905ac254-05fb-4ca2-856d-01e05ee4a7d2 swap swap
defaults 0 0
I’ve never seen this UUID stuff before – how do I add my new partition to
fstab? I’ve been reading that UUID is related to the GPT but is there a way
for me to add this partition?
UUID is a way to uniquly identify a disk, partition, lvm, etc. It is never
supposed to change where your /dev entry might if you were to add disks,
rearrange, etc, and is now the standard way to reference storage media on
several linux distributions.
I know how to do if for a real disk or even LVM but not sure about a raid
array but the following link might work:

Also, what is the maximum partition size under Core 10?
Can't help you there.
Thanks for your time,
Paul
