Dear list, According to the Lustre manual, Since 1.6, Lustre support root squash. My question is how to write nosquash_nid, if I want to support more than 1 machine with no root squash. Suppose I want to support "192.168.50.12~192.168.50.40", I have tried [root at mds01 ~]# echo "192.168.50.[12-40]@tcp" > /proc/fs/lustre/mds/besfs-MDT0000/nosquash_nid [root at mds01 ~]# cat /proc/fs/lustre/mds/besfs-MDT0000/nosquash_nid LNET_NID_ANY According to the manual, that means the format is not right. Any ideas ? -------------- Lu Wang 2009-01-07
