Comment 18 for bug 320638

I'm using SATA drives for LVM on RAID 1. RAID is configured with internal bitmap, so resyncing is quite fast.

In order to do the best kind of backup, I replace my drives to keep backups of complete systems.
There is a very good reason for this, since in the case of a complete desaster I simply take the last backup disk and use it in a working hardware.

So, sometimes it would be quite useful, to also use some USB external storage to connect a hard drive.
But, because of this error, the whole procedure is not possible.

I know it works with eSATA,
but this error claims always with USB connected drives.

Using rsync is not as simple as using a hotplug script that initiates raid resync.

I don't know, how it behaves with USB3.
