Repeat at least three times: Storage requires planning. xfs_growfs only works on contiguous LBA sectors. The free space to be grown into must begin one LBA sector after the last LBA sector of the current XFS filesystem. If XFS resides on a partition, then the partition itself must be expanded into the free space before XFS can be grown into the newly expanded partition. This seems to be your situation. Resizing partitions is not a fun exercise, and if not done properly you can lose everything, literally. If a block device is directly formatted with XFS things are easy. Simply expand the block device capacity, then run xfs_growfs. Because of the limitations up above, those wishing to add capacity using partitions, in an ad hoc manner, such as you seem to desire here, put their block device space in LVM volumes. LVM can create a linear LBA address space from little pieces of capacity strewn all over the place on many different storage devices, regardless of their native LBA addressing. I don't really care for this method either. I've worked with ESX and bare metal hosts on FC SANs fairly extensively. For each of my guests/hosts I assign a 10GB LUN for the guest's boot/root filesystems, and a separate LUN(s), sized appropriately, for its data volume(s). I directly format each LUN, no partitions. In the event I need to expand a LUN to increase capacity, xfs_growfs simply works, the way it should, with no hoop jumping. If you need PIT snapshot capability you must use LVM, unless your storage has a PIT snapshot facility, or you use VMware's snapshot utility. -- Stan _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
