Description of problem: Looks like I should have tested other volume types when filing bug 1366745. [root@host-119 ~]# lvcreate --yes --type cache-pool -L 500M test/cpool Using default stripesize 64.00 KiB. Logical volume "cpool" created. [root@host-119 ~]# lvcreate --yes --type cache -L 500M test/cpool Using default stripesize 64.00 KiB. Logical volume "lvol1" created. [root@host-119 ~]# lvcreate --yes --type thin-pool -L 500M test/tpool Using default stripesize 64.00 KiB. Logical volume "tpool" created.

Well - the message got there because of some validation unification for raid code. I agree the message should be not displayed when just ordinary linear LV is created (--stripes 1) (linear is just sub-case of default stripe type being created)
Addressed primarily with upstream patch: https://www.redhat.com/archives/lvm-devel/2017-November/msg00085.html (But few more surrouding patches were added as well to improve stripe handling on cmdline)
