Back
Many thanks for the responses from Jussi, Arjan and Stephen,
I have tried the -b4096 option and it appears to be building a file
system
with a maximum size of 4TB. The mke2fs process is still going on as I
type,
but it does look very promising indeed.
As for the RHEL-4 distribution, I did log on the RHN website to check
my subscription channels. I can find the various RHEL AS V4 kits, but I
cannot see AS V4 - U1. Do you mean U1 being one of the RHEL AS Beta,
Extra,
or ExtraBeta?
There does not seem to be a summary of what they are?
On the system concerned, I have already applied up2date with the latest
kernel.
It is running under
Linux ggspsfs2.ag.rl.ac.uk 2.6.9-5.0.5.ELsmp #1 SMP Fri Apr 8 14:29:37
EDT 2005
x86_64 x86_64 x86_64 GNU/Linux
Attached is the system information on the machine.
Many thanks once again.
Peter

There was an e2fsprogs bug in RHEL-4's initial release for filesystems
>4TB; that is fixed in U1. If you're running devices larger than 2TB,
you really want to upgrade to U1; it includes other fixes for things
like device-mapper on large devices.
For the unfixed e2fsprogs, passing a blocksize explicitly with "mke2fs
-b4096" should be a workaround for the 4TB wrap problem.
