Description

the -o option to setstripe where you can specify the OSTs to use works on files but gets an error when you do the same thing on directories.

[root@Lustre-TG1 lustrefs]# mkdir testdir
[root@Lustre-TG1 lustrefs]# lfs setstripe -o 0-3 -c 4 testfile
[root@Lustre-TG1 lustrefs]# lfs getstripe testfile
