Max filesystem size for ext3 using Adaptec RAID 5 on 64 bit CentOS
We are strategizing a set of backup servers and I have been trying to deduce wha the maximum size of each RAID 5 array should be to match the OS we are using. We are currently running CentOS 4.3 64 bit. We have planned a 2 TB RAID 5 array for testing but we will need to set up several larger ones for production. I have poked around and I see people mention limits like 2TB max file size and 32TB max filesystem size. Many of these were mention 2.4/2,5 kernels and neither specified 32 bit vs 64 bit. Can someone please provide the following: max file size for 2.6.9 64 bit CentOS kernel max partition/fielsystem size for the same. Thanks Doug -- What profits a man if he gains the whole world yet loses his soul?
