is related to LU-12521 print_instance() incorrect if fsname ... Resolved
Severity: 3
Rank (Obsolete): 9223372036854775807

 Description   

The lfs/lctl pool_list command incorrectly re-uses the path as pool prefix when printing pools, e.g. with a fresh llmount:

 

[root@vm0 ~]# lctl pool_new lustre.foo
lfs Pool lustre.foo created

[root@vm0 ~]# lctl pool_list /mnt/lustre
Pools from /mnt/lustre:
/mnt/lustre.foo

/mnt/lustre.foo is not a valid pool name and scripts looking at this output to use directly with lfs setstripe -p will now fail

On old 2.7 at least, this would correctly print lustre.foo instead

 
The fix is very much straightforward, I'll submit something right away.
