I installed 1 MDS , 2 OSS/OST and 2 Lustre Client. My MDS shows:



[code]

[root at MDS ~]#  lctl list_nids

10.94.214.185 at tcp

[root at MDS ~]#



[/code]



On Lustre Client1:

[code]

[root at lustreclient1 lustre]# lfs df -h

filesystem summary:        70.9G        3.2G       64.0G   5% /mnt/lustre





[/code]



But Lustre Client2 is displaying it as:



[code]



[root at alpha ~]# lfs df -h

OST000b             : inactive device



filesystem summary:        35.4G        1.6G       32.0G   5% /mnt/lustre



[/code]



Why is it showing inactive device on one machine while not in another?
