Description

[root@clnt ~]# mkdir /mnt/lustre2/foo
[root@clnt ~]# lfs getstripe /mnt/lustre2/foo | sed 'l'
/mnt/lustre2/foo$
/mnt/lustre2/foo
stripe_count:   1 stripe_size:    1048576 stripe_offset:  -1 $
stripe_count:   1 stripe_size:    1048576 stripe_offset:  -1 
[root@clnt ~]# lfs getstripe -c -s /mnt/lustre2/foo | sed 'l'
stripe_count:   1 stripe_size:    1048576 $
stripe_count:   1 stripe_size:    1048576 
[root@clnt ~]# lfs getstripe -c /mnt/lustre2/foo | sed 'l'
1 $
1 
[root@clnt ~]# 

This is particularly annoying for parsing in scripts and has been unveiled in LU-3858 and associated Gerrit Change #7495, where a new auto-test was developed using "lfs getstripe".

Hello Bruno,

It did not cost me much time to prepare the patch since Andreas had already pointed out where the problem is and how to fix.

Hello Li, seems that after Andreas raised this problem, during your change #7495 review, you already worked on it and had a patch ready to go !!
Thanks for you help.
