Hi,

I'm preparing an XFS partitioned 2TB hard disk in an external enclosure, using openSUSE 13.1 64 bit, but I intend to use it under 13.1 32 bit.

Should I expect problems?

I read about an issue regarding xfs and 32 bit vs 64 bit on big partitions, but I'm unsure about what it affects this "early" in the morning :-)


What I have read recently is about a weird issue with layout on external enclosures, regarding the sector size of 512/4096. Apparently when accesing via usb the bridge chipset can lie to the kernel or mkfs.xfs so that it thinks that the disk has 512 byte sectors (this does not affect sector start alignment on 1 MB, it's a different issue).

Thus, to avoid this possible issue, I want to format the disk using SATA directly, which means using my 64 bit desktop machine, not the older 32 bit machine which doesn't have sata, where the disk is going to be used mostly.


(If this question is too specific for this mail list, I'll ask on the xfs mail list instead)
