GPFS文件系统限制？

gpfs哪个版本，得查一下红皮书

4.1版本的，我在官方文档中找到了。
• Determine whether you are within GPFS limits. Starting with GPFS 3.1, the structural limit on the maximum number of disks in a file system increased from 2048 to 4096; however, the current version of GPFS still enforces the original limit of 2048. Should your environment require support for more than 2048 disks, contact IBM® to discuss increasing the enforced limit. (However, the number of disks in your system is often constrained by products other than GPFS.)
