Is anybody using USB 3.1 mass storage devices with illumos? (FWIW, I'm using
SmartOS)
I've had a problem with several different multi-bay drive enclosures where the
enclosure is reported instead of the individual drives. This causes zfs to
assign the same devid to each drive, and while I can create a zpool if I try
replacing a drive I can't because it says a different device (the last device)
is already part of the pool. For example, if I `zpool attach test c1t0d0
c1t0d1` the error message says that c1t0d3 is already part of the pool.
This happens with multiple manufacturers, and different number of devices in
the enclosure. The two main units I have for testing right now are a four-bay
QNAP TR-004 and a dual-bay HornetTek Gemini. These devices use a USB-C
connector at the device, and a USB-A connection to the computer. Both exhibit
the same problem.
Using the two HornetTek enclosures, for example gives this output form iostat:
# iostat -En | grep Serial
Vendor: ASMT Product: ASM1352R-PM Revision: 0 Serial No:
000000000000000
Vendor: ASMT Product: ASM1352R-PM Revision: 0 Serial No:
000000000000000
Vendor: ASMT Product: ASM1352R-PM Revision: 0 Serial No:
000000000000000
Vendor: ASMT Product: ASM1352R-PM Revision: 0 Serial No:
000000000000000
And from zdb:
# zdb | grep devid
devid: 'id1,sd@n5000000000000001/a'
devid: 'id1,sd@n5000000000000001/a'
devid: 'id1,sd@n5000000000000001/a'
devid: 'id1,sd@n5000000000000001/a'
Putting the same disks into a usb 2 enclosure (and using a USB type B connector
at the device), is entirely different:
# iostat -En | grep Serial
Vendor: HITACHI Product: HUA723030ALA640 Revision: Serial No:
Vendor: HITACHI Product: HUA723030ALA640 Revision: Serial No:
And because the serial number is blank rather than a duplicate (though
obviously invalid) value, the devids aren't duplicated and the pool behaves
properly.
Has anybody else experienced this? Anybody know what's going on here?
