Hi List,

Im creating some Thinpool here, but

# lvcreate -i 2 -I 1024 -c 4096 --type thin --thinpool dmivg/winthinpool
dmivg -V 3500G /dev/sde1 /dev/sdf1
  Command does not accept option: --stripes 2.
  Command does not accept option: --stripesize 1024.

doesnt work, but

# lvcreate -i 2 -I 1024 -c 4096 -L10G -T dmivg/pool -V 3500G --name
  WARNING: Sum of all thin volume sizes (3,42 TiB) exceeds the size of
thin pool dmivg/pool (10,00 GiB)!
  For thin pool auto extension activation/thin_pool_autoextend_threshold
should be below 100.
  Logical volume "winthinpool" created.

does. Whats the difference between them?

My actual build:

# lvcreate --version
  LVM version:     2.02.172(2)-git (2017-05-03)
  Library version: 1.02.141-git (2017-05-03)
  Driver version:  4.35.0
  Configuration:   ./configure --enable-lvmetad --enable-lvmpolld
--enable-udev_sync --enable-udev_rules --enable-applib --enable-cmdlib
