Logically concatenating a thin-provisioned block storage volume with a standard boot volume

A method for use with a boot volume, which is not thin-provisioned, on at least one remote device, the method comprising:

• using a processor of a local device, allocating, for storage of data, a thin-provisioned block storage volume on the at least one remote device, and
• using the processor, logically concatenating the thin-provisioned block storage volume with the boot volume with respect to read and write operations by a file system running on the local device, by:
• mapping any logical address provided by the file system and less than a size of the boot volume to an equivalent physical address in the boot volume, and
• mapping other logical addresses provided by the file system to provisioned physical addresses in the thin-provisioned block storage volume.

A computer software product for use with a boot volume, which is not thin-provisioned, on at least one remote device, the computer software product comprising a tangible non-transitory computer-readable medium in which program instructions are stored, which instructions, when read by a processor of a local device on which a file system runs, cause the processor to:

• allocate, for storage of data, a thin-provisioned block storage volume on the at least one remote device, and
• logically concatenate the thin-provisioned block storage volume with the boot volume with respect to read and write operations by the file system, by:
• mapping any logical address provided by the file system and less than a size of the boot volume to an equivalent physical address in the boot volume, and
• mapping other logical addresses provided by the file system to provisioned physical addresses in the thin-provisioned block storage volume.
