[LU-12130] lod: start offset is not checked when pool is retained

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.16.0
• Severity: 3

Description

The following sequence of commands:

#! /bin/bash
 
lctl pool_new lustre.ppp
lctl pool_add lustre.ppp OST0000
mkdir /mnt/lustre/dir
lfs setstripe -p ppp /mnt/lustre/dir
lfs setstripe -i 1 /mnt/lustre/dir
touch /mnt/lustre/dir/file

end with failed touch:

Pool lustre.ppp created
OST lustre-OST0000_UUID added to pool lustre.ppp
touch: setting times of ‘/mnt/lustre/dir/file’: No such file or directory
[root@sl751 LUS-7180]# 

This is because on lfs setstripe -i1 pool ppp is retained but OST0001 is not in the pool.
