[LU-17713] Check the length of mdd append_pool name before setting it

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

Description

There is currently the limit of 15 characters for a pool. However, when customer tried the following with 16 characters:

# lctl set_param -P mdd.users*.append_pool="users_append_hdd"

the command succeeded fine. But it removed the last character, what customer did not notice at first.

# lctl get_param *.*.append*
mdd.interact-MDT0000.append_pool=users_append_hdmdd.interact-MDT0000.append_stripe_count=1

I will create a patch to fix it.
