Greetings.
I am trying to create a 10TB (approx) ext3 filesystem. I am able to successfully create the partition using parted, but when I try to use mkfs.ext3, I get an error stating there is an 8TB limit for ext3 filesystems.
I looked at the specs for 5 on the "upstream" vendor's website, and they indicate that there is a 16TB limit on ext3.
Has anyone been able to create a ext3 filesystem larger than 8TB?
If ext3 isn't an option, has anyone used the kmod-xfs-smp.i686 module mentioned on the centos site? Surely it doesn't have an 8TB limit...
specs:
Centos 5.1 kernel-2.6.18-53.1.14.el5 3Ware 9550SXU 12port raid card
Am I just walking into a big nightmare?
Any thoughts would be greatly appreciated.
I think it *theoretically* should work as ext3 should to 16TB. However, we ran into issues with userland tools and such. Possibly related to x86_64 vs i386 stuff, but in the end to avoid continued troubleshooting we just used centosplus + jfs. Works perfectly for our 10TB filesystem.
I'm curious what you store that you need 10TB of linear storage?
I have had 4-6-8TB storage systems, but the storage was always divvied up between different applications.

Ross,
We basically store video image sequences (edited and source) and audio/video files on our servers. We are an editing and broadcast design facility, doing mostly HD work. The files are relatively large, and there are a lot of them.
I am trying to "max out" our current server population, moving from 250 and 500 gig drives to the Seagate 1TB enterprise (ES.2) SATA drives using the 12 port 3ware raid card.
I have at least 4 servers that I am wanting to upgrade this way.
They're just file servers running NFS and Samba.
Do I *need* a 10TB partition? No, not really. I could segment into 2 5TB partitions if needed, and I may still end up doing that. I am beginning to wonder if the >8TB ext3 limit has been vetted enough. It is just easier for the users if it was one partition.
I have to say when the mkfs.ext3 code hasn't been changed to allow >8TB partitions without adding the -F, (which did seem to work) it gives me pause.
Naively perhaps, I didn't think it would be an issue.
Thanks,
Monty
