Public bug reported:
Hi,
I have a system with a Nec PCI USB 3 adapter (Renesas Technology Corp.
uPD720201 USB 3.0 Host Controller) with a Lindy USB3 disk case for 2
disks attached to it (JMicron Technology Corp. chipset) and two 1TB
disks inside. The Lindy disk case is configured to show the 2 disk
units (in windows it supports fake raid to with proper dip-switch
configuration).
Linux is configured to see the two disks as a software raid 1 unit. LVM
is set up on top of the raid. Ext4 partitions are created in LVM.
Apparently things work just fine. However, if I have heavy disk
activity (e.g. copy a large iso file to the raid storage), there are
very frequent issues. In the worst case the machine freezes (flashing
leds) trashing all the last data written on the raid storage. When the
machine comes up the raid starts resync which is a painful activity. No
visible oops, nothing in syslog. In the best case, the array simply
looses sync.
Even when things work fine, the disks in the array make clunky noise
that does not seem proper.
Also tried with a VIA USB3 controller and with the motherboard
integrated USB2 controllers. With USB2 things are much slowlier, but the
result is invariably the same.
