Description

The codes have some inconsistency about the length of pool name. Creating and setting a 16 byte pool name to a directory succeeds. But creating a file under that directory fails. Following script will reproduce that problem.

#!/bin/bash
FSNAME=server1
MNT=/mnt/lustre
lctl pool_new $FSNAME.aaaaaaaaaaaaaaaa
lctl pool_add $FSNAME.aaaaaaaaaaaaaaaa $FSNAME-OST0000
mkdir $MNT/dir2
lfs setstripe -p aaaaaaaaaaaaaaaa $MNT/dir2
dd if=/dev/zero of=$MNT/dir2/file bs=1M count=100
