I’m pleased to announce another release candidate for GEOM_VIRSTOR, A FreeBSD kernel GEOM class providing storage virtualisation facility, regardless of type of underlying devices or its usage. It is a kind of “virtual memory” for disks – you pre-allocate address space (i.e. make a large virtual drive) and worry later about where to find physical space to back it.
This is a bug fix release – a bug that can cause data corruption on large-ish virtual drives (1 TB+) was fixed.
The development snapshot can be found here – everyone (or, to be precise, everyone with 7-CURRENT) is invited to test it.
