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.
