I'd like to set up a tablespace area of about 8GB, made up of 4x2GB
disks striped together to a metadevice with the Online Disksuite. I'm
assuming that because of that size, llseek's must be used, and in the
man pages there is an odd blurb:
Although each file has a 64-bit file pointer associated with
it, existing file system types do not support the full range
of 64-bit offsets. In particular, non-device files remain
limited to offsets of less than two gigabytes. Device
drivers may support offsets of up to 1024 gigabytes for dev-
ice special files.
Anyone have an opinion on that? In particular, is it less efficient
than creating 4 striped md's (500MB/disk), each with 2 GB, allowing only
lseek's? The md's would only be used as raw devices -- no ufs on them.

Always do things in chronological order; it's less confusing that way.
