 Representation of an SPDK block device (spdk_bdev) with an lvol implementation.
-A logical volume block device translates generic SPDK block device I/O (spdk_bdev_io) operations into the equivalent SPDK blob operations. Combination of lvol ID and lvolstore UUID gives lvol_bdev name in a form "uuid/lvolid". block_size of the created bdev is always 4096, due to blobstore page size. Cluster_size is configurable by parameter. By default it is 1GiB.
+A logical volume block device translates generic SPDK block device I/O (spdk_bdev_io) operations into the equivalent SPDK blob operations. Combination of lvol ID and lvolstore UUID gives lvol_bdev name in a form "uuid/lvolid". block_size of the created bdev is always 4096, due to blobstore page size. Cluster_size is configurable by parameter.
 Size of the new bdev will be rounded up to nearest multiple of cluster_size.
 By default lvol bdevs claim part of lvol store equal to their set size. When thin provision option is enabled, no space is taken from lvol store until data is written to lvol bdev.
