2.4. Fibre Channel Storage Devices

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

RequirementDescription
Device Type

FC RAID array or JBOD
Note: Make sure that the devices can operate reliably when heavily accessed simultaneously from multiple initiators.
Note: Make sure that your GFS configuration does not exceed the number of nodes an array or JBOD supports.

Size2 TB maximum per GFS file system. Linux 2.4 kernels do not support devices larger than 2 TB; that limits the size of any GFS file system to 2 TB.
