Description Matus Kocka 2016-11-09 09:58:26 UTC 
Hello 

I done this: 

pvcreate /dev/sd[d-p] -y
vgcreate vg /dev/sd[d-p]  -y
lvcreate -n testLV1 -i13 -l100%vg vg -y

  Using default stripesize 64.00 KiB.
  Only up to 8 stripes in striped supported currently.
  Run `lvcreate --help' for more information.

... if I tried different stripe size

lvcreate -n testLV1  -I256 -i13 -l100%vg vg -y
  Only up to 8 stripes in striped supported currently.

these are the disks

I am pretty sure, that this works in RHEL-7.2.

If I use -i8 it works: 

lvcreate -n testLV1  -I256 -i8 -l100%vg vg -y
  Rounding size (3097107 extents) down to stripe boundary size (3097104 extents)
  Wiping xfs signature on /dev/vg/testLV1.
  Logical volume "testLV1" created.

Yes, this is a regression - there's already bug filed for that as bug 1389546, closing this one as dup.
