Our local vendor built us a Supermicro/Adaptec system with 16x1TB SATA drives. We have a 12TB partition that they built as EXT2. When I tried to add journaling, it took forever, and then the system locked up. On reboot, the FS was still EXT2, and takes hours (even empty) to fsck. Based on the messages flying by I am also not confident fsck rally understands a filesystem this large.
We recently upgraded one of our external RAID boxes from 3TB to 10TB, and are wondering much the same thing.
ext3 filesystems are supported on SL5.2, even if mke2fs won't create the filesystem without being forced with the -F flag. I still have concerns about performance and recovery though which makes me want to look at XFS. The 10TB ext3 filesystem has been stable during a week or so of casual testing, although the time required by fsck is reaching close to 6 hours (with 7TB data on the fs).
Our server is running i386 though could be reinstalled as X86_64 (which I believe is required for stable XFS).
