Using kickstart on large disks

Thanks everyone for your replies. See my comments below:

Well, firstly I wanted to use the "logvol" option because it does a lot of work for you, but the main problem with a %post approach is that one of the RPMs that gets installed puts a lot of stuff into /db.

I actually use a hack right now where that RPM uses lvextend & resize2fs to expand the volume to the full 16TB before installing stuff into it.

Thanks Digi, and agreed. I currently use the ugly workaround I mentioned above and it works fine, but the fix to anaconda seems really easy to me. More importantly, I feel that this is something that other folks will run into and a fix would save them a lot of headache.

Thanks Pablo. I will look at GFS but my needs are fairly simple and don't really necessitate a cluster file system. With my current lvextend workaround described above, Ext4 is doing a great job with the 16TB partition. I just wish that anaconda/kickstart wouldn't limit Ext4 partitions to 8T.

Yeap that is exactly my problem, except that I'm using Ext4 and not XFS. I just wonder if the current 8TB limit is intentional (I'm no filesystem expert) or just an oversight when the Ext4 FS type was extended from Ext2.
