This days reinstalling my SGIs, some time before I'd read than EFS is faster filesystem than XFS specially in lower systems with old scsi drives. I'm my experience my old Crimson with 1Gb Disk Drive and IRIX 5.3 in XFS format works too slow, apps works good but usability of IRIX or install apps it's too slow, when change to IRIX 5.3 in EFS all works fast and the experience using IRIX or install new apps works fast and good.
Now I'm trying to reinstall my O2 R5000 with IRIX 6.3 in EFS format ( this O2 with IRIX 6.5.22m and XFS works too slow like Crimson with XFS ), the problem is I have a 9,1 Gb disk drive in the O2 and I can't repartition as lower size volume in the form of IRIX 6.3 can install in EFS, Installer always say someone like "not possible make large EFS makefilesytem".
I'd try to use some confusing guides on internet to resize partition as lower than 8 Gb, but can´t do it works.

Someone can help me with a step by step instruction to reformat/resize my HD to work in EFS ? I want make a 7,8 Gb partition or similar size.

Thanks in advance.

Yes I'm know the limit of 8 Gb , but on low profile SGI general perfomance is better than XFS. I'm use the guide you link but maybe some terms of guide don't understand at all and not work for me. Later I'll post a screenshot of my fx partition table.
