It seems to be a hardware problem with da5. After the latest
crash, I had the following in dmesg:
(da5:ahc4:0:2:0): SYNCHRONIZE CACHE. CDB: 35 0 0 0 0 0 0 0 0 0
(da5:ahc4:0:2:0): NO SENSE
- after obliterating the vinum configuration I created the volume
without da5, and I have now successfully copied 250+MB to the filesystem.
I would have thought that hardware errors like this could be handled
in a slightly more controlled manner, though.
