Description Corey Marthaler 2016-08-12 17:01:45 UTC
Description of problem:

# 7.2 (lvm2-2.02.130-5.el7_2.5.x86_64)
[root@host-006 ~]# lvcreate -m 1 --type mirror -n transform -L 25M test
  Rounding up size to full physical extent 28.00 MiB
  Logical volume "transform" created.




# current 7.3 (lvm2-2.02.163-1.el7) mirror attempt
[root@host-082 ~]# lvcreate -m 1 --type mirror -n transform -L 25M test
  Using default stripesize 64.00 KiB.

[root@host-082 ~]# lvcreate -m 1 --type raid1 -n transform -L 25M test

Comment 2 Alasdair Kergon 2016-08-15 16:27:10 UTC
It's supported if there's more than one stripe.  Otherwise the message needs removing.

Comment 5 Corey Marthaler 2016-08-17 20:32:59 UTC
Fix verified in the latest rpms. Stripe message is no longer present.


[root@host-123 ~]# lvcreate -m 1 --type mirror -n transform -L 25M raid_sanity

  Logical volume "transform" created.

[root@host-123 ~]# lvcreate -m 1 --type raid1 -n transform1 -L 25M raid_sanity
