Re: [HPDD-discuss] [Lustre-discuss] Vdev Configuration on Lustre
This should be possible by specifying the pool configuration for mkfs.lustre as you do
with zpool:
mkfs.lustre --backfstype zfs {other opts} {poolname/dataset} mirror sde sdf mirror sdg
sdh
There is also a bug open to improve the mkfs.lustre(8) man page to describe the ZFS
options better: https://jira.hpdd.intel.com/browse/LU-2234

Hi All,
In Lustre, is it possible to create a zpool with multiple vdevs -
E.g.:
# zpool create tank mirror sde sdf mirror sdg sdh
# zpool status
pool: tank
state: ONLINE
scan: none requested
config:
NAME STATE READ WRITE CKSUM
tank ONLINE 0 0 0
mirror-0 ONLINE 0 0 0
sde ONLINE 0 0 0
sdf ONLINE 0 0 0
mirror-1 ONLINE 0 0 0
sdg ONLINE 0 0 0
sdh ONLINE 0 0 0
This will allow us to have a single OST per OSS, with ZFS managing the striping across
vdevs.
