Thank you to Stan and Dave for helping me through this. Ok, here's the file, printed below. Basically, I'm running the following commands under Ubuntu 12.10: Type mkdir /mnt/fp Type mkdir /mnt/hr20 Type mount -t xfs -o rtdev=/dev/sda3 /dev/sda2 /mnt/fp Type mount -t xfs -o rtdev=/dev/sdb3 /dev/sdb2 /mnt/hr20 Type xfsdump -J - /mnt/hr20 | xfsrestore -J - /mnt/fp When run, I get this as my output: xfsdump: WARNING: write to stdio failed: 32 (Broken pipe) xfsdump: ending media file xfsdump: media file size 18874368 bytes xfsdump: dump size (non-dir files) : 13698056 bytes xfsdump: NOTE: dump interrupted: 16 seconds elapsed xfsdump: Dump Status: INTERRUPT This happens each time. In the forum where this copy procedure was suggested, they've been reporting that the latest xfsprogs is creating these errors, which didn't happen under at least somewhat earlier versions. The version of xfsprogs should be in the file, but it was just downloaded a few days ago using git.
