Ok, well that is a start then.  I am running Redhat's latest kernel
2.4.20-20.9 though I also have 2.4.0test4 on the machine.  I haven't tried
it under 2.4.0test4 though.  I just didn't have enough time this morning
when the error surfaced.  Are they in 2.4.22?  Because looking through the
changelog, I see a bunch of AC's and other fixes for IDE items, but I don't
see anything about this boundrey?  Did it go in before then?

Thanks for the help

IDE limit is 137GB, not 128GB.

2.6.0-test4 should be okay, unless you have Promise PDC20265,
then you should use 2.6.0-test5 (allows LBA48 DMA on PDC20265).

Latest 2.4-ac may be even better if you have i.e. ALi IDE controller.
It will use DMA transfers for < 137GB area and PIO for > 137GB,
whereas 2.6 will always use PIO.

No, it's not the same... 137GB == 128GiB ;-).

Well I do have a PDC20265, so I installed the 2.6.0test5 rpm from

http://people.redhat.com/arjanv/2.5/RPMS.kernel/

That allowed me to get access to the whole drive.  I made an ext3 filesystem
on it and everything mounted real nice.  Unfortunately, now after about a
minute of hard copying the IDE channels timeout and reset.  I get the
timeout on hdg (which is the 250G drive), but the filesystem on hdf (which
is a 120G drive that I am copying from) get corrupted.  I didn't have this
problem with any of the other kernels, so I think it might have something to
do with what went in for test5.  I am still looking at that though.  I am
also going to try moving the drive that is currently hdf onto the standard
motherboard channels so that it isn't on that controller.  I hope to get the
source rpm for 2.6.0test5 and the .config for it tonight and try recompiling
with some different options.  Does any one have any suggestions on what I
should look for?

Thanks for all you help you guys have been really great.

Great!!! Nice info.  That goes a long way toward explaining why it wouldn't
mount.  It was so weird since mkfs.ext3 didn't error or anything, it just
finished normally, but then nothing would mount the drive.  Thanks again.

No I am pretty sure that I don't have an open log files.  This drive holds
mainly movies and songs.  I still got the error after a reboot, so I don't
think it is possible that there is anything open on it, especially anything
taking up 112G.  It is just a desktop machine so, that would be a real
rarity on it.  Is it possible that there is some error in the file
structure?  The filesystem is less than 12 hours old, but in that 12 hours
there have been a lot of writes to it (namely the whole 128G) so is it
possible something has been corrupted?

Like I said it was a real odd error to get, but this is the first time I
have worked with drives this big, so I didn't know if this was something
everyone knew about.

128G Limit in Reiserfs? Or the Kernel? Or something else?

[Norris, Brent]

I seem to have hit an odd limit, that I didn't think existed.  I have a 250G
WD IDE hard drive that I have just installed.  Since I couldn't put a Ext3
filesystem on it (mount wouldn't recognize it) I decided to put a ReiserFS
filesystem on it.  Since I have done that I have added 128G of data to the
drive.  Now when I attempt to copy more data to it I get an error that there
is no more space on the drive.

I can touch a 0 byte file and delete it, but as soon as I attempt to move
anything over there with any size it errors out.  df shows me as having 112G
free on that drive so I am a little confused as to what is giving me this
error.  Is it the kernel that is not letting me write to the rest of the
drive or reiserfs or something completely different?  Any help would be
welcome.  Thanks.

Reiser can definitly do larger file systems than that (I have a Reiser 
file system with over 300GB on).

Its worth trying a df -i to make sure you haven't run out of inodes - 
but then you say you can create empty files.

I have about 2 filesystems currently at 600Gig.

Reiser has no inodes so I guarantee your out but it's irrelevant.
What does df -k actually show?  You sure you don't have a process with
an open log file that's been removed?

Its an IDE issue. You need 48-bit addressing to access above 128GB on
IDE drives. I'm not sure exactly what the IDE guys need from you...
Post the output of dmesg, lspci, .config.

Testing the latest kernel would be an idea, if you are not running it.

This probably has to do with the 128GB IDE disk boundary problems that 
have been recently coming about and nothing to do with Reiserfs (except 
that Reiserfs gets stuck with it). What version of the linux kernel are 
you using? Ie. provide some more info like what's 'uname -a' say on your 
system. There's been a few patches go by this list to fix this disk size 
problem. They should also be in the latest kernel releases too.

Just FYI, we have lots of ext3 filesystems that are 2TB in size, so I don't
think it is an ext3 problem.  What could be happening though is that when
you mke2fs the filesystem with your IDE problem it wraps writes over 128GB
back to zero and overwrites the superblock so mount doesn't see the ext3
superblock anymore.
