has anyone had any issues with using one large gpt partition of 5TB on a raid 6 setup with a 3ware raid controller. i am using the partition as a basic file sharing backup repository, nothing fancy. are there any limitations to using gpt under ntfs that i should be concerned about? the other option would be to split the array into 2TB ones and make non gpt. if further info is needed i can provide. thanks.
You should be fine. I'll just throw out the usual warnings:
- Too many files in a single directory (seems ~50k per directory is a colloquially accepted "safe" limit)
- Monitor the system, using large SATA disks causes rebuilds to really tax the system and usually take a whole day or more to rebuild. The error rate during something like that is approaching whole percentage numbers (most people don't really like the idea that 1 in 100 rebuilds will irreconcilably fail).
- For any new controller, make sure you get the latest firmware and drivers. Burning the drives in for a couple days to weed out infant death is a good idea too.
