gpfs 多路径问题
gpfs4.1，centos7.3 初始化的时候就是不好用，错误如下
[root@gpfs ~]# mmcrfs fpofs0 -F /etc/gpfsdisk_profile -B 1m -n 16 -m2 -M2 -r2 -R2 -T /gpfs/fpofs0 -A yes -i 4096 -S relatime -E no
The following disks of fpofs0 will be formatted on node gpfs.node2.com:
fpo_linux1_NSD_Data_11: size 614400 MB
fpo_linux1_NSD_Data_22: size 614400 MB
Formatting file system ...
Disks up to size 5.2 TB can be added to storage pool system.
