Tried 3.10.5 from the mainline ppa. The situation if possible is even worse.
At boot I get tons of I/O errors on the usb3 disks that make up the raid components. In dmesg I find [ 32.202815] sd 8:0:0:0: [sdf] No Caching mode page present [ 32.202831] sd 8:0:0:0: [sdf] Assuming drive cache: write through [ 33.740587] sd 8:0:0:1: [sdg] No Caching mode page present [ 33.740603] sd 8:0:0:1: [sdg] Assuming drive cache: write through [ 37.195945] usb 3-2: USB disconnect, device number 3 [ 37.258746] sd 8:0:0:0: [sdf] Unhandled error code [ 37.258750] sd 8:0:0:0: [sdf] [ 37.258752] Result: hostbyte=DID_NO_CONNECT driverbyte=DRIVER_OK [ 37.258755] sd 8:0:0:0: [sdf] CDB: [ 37.258756] Read(10): 28 00 00 00 00 00 00 00 08 00 [ 37.258762] end_request: I/O error, dev sdf, sector 0 [ 37.258773] Buffer I/O error on device sdf, logical block 0 [ 37.258793] sd 8:0:0:1: [sdg] Unhandled error code [ 37.258794] sd 8:0:0:1: [sdg] [ 37.258795] Result: hostbyte=DID_NO_CONNECT driverbyte=DRIVER_OK [ 37.258797] sd 8:0:0:1: [sdg] CDB: [ 37.258798] Read(10): 28 20 00 00 00 00 00 00 08 00 [ 37.258802] end_request: I/O error, dev sdg, sector 0 [ 37.258811] Buffer I/O error on device sdg, logical block 0 [ 37.258814] ldm_validate_partition_table(): Disk read failed.
