如何调整fpg的归属节点,比如20800,四节点file persona系统
cli% showfs
Node FSNode State Active InCluster -----Version------ ---N:S:P--- BondMode MTU
0 Yes Running Yes Yes 1.5.1.900-20180914 0:4:1 6 1500

2 Yes Running No Yes 1.5.1.900-20180914 2:4:2,2:4:1 6 1500
3 Yes Running No Yes 1.5.1.900-20180914 3:4:2,3:4:1 6 1500

当前fpg在node0上,如何调整到node1/2/3
cli% showfpg -d lafpg

lafpg.1 4514 3,2,1,0 10.00
以下操作均需要维护窗口,IO会掉零1min左右,一般系统均可自动重连
调整到本节点对的另一个节点使用setfpg -failover lafpg即可
若要调整到另一个节点对下,则需要使用setfpg -primarynode 2 lafpg
