[root@ec01 ~]# lfs setstripe -C 2000 /lustre/out
[root@ec01 ~]# lfs setstripe -C 2001 /lustre/out
lfs setstripe setstripe: invalid stripe count '2001'
To create a file with specified striping/composite layout, or
create/replace the default layout on an existing directory:

'lfs setstripe -C 2000' works, but '-C 2001' doesn't work. that's expected.

However, 'lfs setstripe -C -1' can be set beyond overstripe count 2000.

[root@ec01 ~]# lfs setstripe -C -1 /lustre/out
[root@ec01 ~]# lfs getstripe /lustre/out/a | grep 0x | wc -l
