[Linux-cluster] gfs - filesystem size for 64-bit Linux

[Anne Hammond]

The Red Hat documentation for gfs 6.0, page 12, lists the
requirements for storage devices, with a 2 TB TOTAL gfs space
(see below).

We want to run 2 AMD64 servers with Red Hat Linux with a total
of 10 TB data space.

Can we only mount 1 2 TB gfs filesystem? Or can there be several
gfs "filesystems", each with whatever that version of Linux supports
as the max filesystem size? (16TB under 2.6)


 From the docs:
---------------
2.4 Fibre Channel Storage Devices

Table 2-3 shows requirements for Fibre Channel devices that are to
be connected to a GFS cluster.

Size  2 TB maximum, for total of all storage connected to a GFS cluster.
       Linux 2.4 kernels do not support devices larger than 2 TB;
       therefore the total size of storage available to GFS cannot
       exceed 2 TB.

Is anyone out there using > 2 TB gfs on a 64bit system?

Thanks in advance,
