I tried this for many different scenarios and it seems to work pretty well. I only ran into one problematic case: If you remove a device from a multidevice filesystem it crashes. Here's how to reproduce it: truncate -s1g /tmp/test1 truncate -s1g /tmp/test2 losetup /dev/loop1 /tmp/test1 losetup /dev/loop2 /tmp/test2 mkdir /tmp/test ./mkfs.btrfs -L test -d single -m single /dev/loop1 /dev/loop2 mount -o noatime /dev/loop1 /tmp/test ./btrfs dev del /dev/loop1 /tmp/test ./btrfs fi bal start /tmp/test There is no actual restriping involved but the above example does work corretly under 3.1+for-linus whereas it fails with your patches. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
