I've discussed problems with FreeBSD and usb sata drives on this list in the past (as recently as last September), and have given up on FreeBSD as a result of the usb disk problems (I do my backups with usb drives) and other usb-related issues. But I've now replaced the usb enclosures I was using at that time and have acquired some Toshiba usb drives, so with this new equipment, I thought I'd give FreeBSD another try, since generally I prefer it to Linux. But I'm having problems again. Plugging in the Toshiba drives produces entries like this in /var/log/messa= ge: Feb 5 07:22:07 octavian root: Unknown USB device: vendor 0x0480 product 0xa003 bus uhub1 Feb 5 07:22:07 octavian kernel: ugen1.6: <Toshiba> at usbus1 Feb 5 07:22:07 octavian kernel: umass0: <Bulk Only Interface> on usbus1 Feb 5 07:22:07 octavian kernel: umass0: SCSI over Bulk-Only; quirks =3D 0= x0000 Feb 5 07:22:08 octavian kernel: umass0:0:0:-1: Attached to scbus0 Feb 5 07:22:45 octavian root: Unknown USB device: vendor 0x0480 product 0xa003 bus uhub1 Feb 5 07:22:45 octavian kernel: ugen1.7: <Toshiba> at usbus1 Feb 5 07:22:45 octavian kernel: umass1: <Bulk Only Interface> on usbus1 Feb 5 07:22:45 octavian kernel: umass1: SCSI over Bulk-Only; quirks =3D 0= x0000 Feb 5 07:22:46 octavian kernel: umass1:1:1:-1: Attached to scbus1 Feb 5 07:23:18 octavian kernel: ugen1.6: <Toshiba> at usbus1 (disconnected= ) Feb 5 07:23:18 octavian kernel: umass0: at uhub1, port 5, addr 6 (disconne= cted) Feb 5 07:23:18 octavian kernel: (probe0:umass-sim0:0:0:0): AutoSense faile= d Feb 5 07:23:20 octavian root: Unknown USB device: vendor 0x0480 product 0xa003 bus uhub1 Feb 5 07:23:20 octavian kernel: ugen1.6: <Toshiba> at usbus1 Feb 5 07:23:20 octavian kernel: umass0: <Bulk Only Interface> on usbus1 Feb 5 07:23:20 octavian kernel: umass0: SCSI over Bulk-Only; quirks =3D 0= x0000 Feb 5 07:23:21 octavian kernel: umass0:0:0:-1: Attached to scbus0 Feb 5 07:23:22 octavian kernel: da0 at umass-sim0 bus 0 scbus0 target 0 lu= n 0 Feb 5 07:23:22 octavian kernel: da0: <Toshiba External USB HDD > Fixed Direct Access SCSI-4 device Feb 5 07:23:22 octavian kernel: da0: 40.000MB/s transfers Feb 5 07:23:22 octavian kernel: da0: 305245MB (625142448 512 byte sectors: 255H 63S/T 38913C) Feb 5 07:23:56 octavian kernel: ugen1.7: <Toshiba> at usbus1 (disconnected= ) Feb 5 07:23:56 octavian kernel: umass1: at uhub1, port 6, addr 7 (disconne= cted) Feb 5 07:23:56 octavian kernel: (probe1:umass-sim1:1:0:0): AutoSense faile= d Feb 5 07:23:58 octavian root: Unknown USB device: vendor 0x0480 product 0xa003 bus uhub1 Feb 5 07:23:58 octavian kernel: ugen1.7: <Toshiba> at usbus1 Feb 5 07:23:58 octavian kernel: umass1: <Bulk Only Interface> on usbus1 Feb 5 07:23:58 octavian kernel: umass1: SCSI over Bulk-Only; quirks =3D 0= x0000 Feb 5 07:23:59 octavian kernel: umass1:1:1:-1: Attached to scbus1 Feb 5 07:23:59 octavian sudo: dca : TTY=3Dpts/0 ; PWD=3D/usr/home/dca ; USER=3Droot ; COMMAND=3D/sbin/mount /dev/da0s2a Primary Feb 5 07:23:59 octavian kernel: da1 at umass-sim1 bus 1 scbus1 target 0 lu= n 0 Feb 5 07:23:59 octavian kernel: da1: <Toshiba External USB HDD > Fixed Direct Access SCSI-4 device Feb 5 07:23:59 octavian kernel: da1: 40.000MB/s transfers Feb 5 07:23:59 octavian kernel: da1: 305245MB (625142448 512 byte sectors: 255H 63S/T 38913C) There were two drives plugged in here, once. So the 'disconnect' messages are odd -- I did not unplug the drives. Each of the drives has an approx. 160 Gb FreeBSD slice, with a single partition, 'a'. You can see the mount of da0s2a above (slice 1 is a Linux ext2 partition). What I am attempting to do is to rsync da0s2a to da1s2a, which was freshly newfs'ed when I started this. The behavior I see is that the disk lights blink for awhile, indicating copying going on, and then they stop for quite awhile, a minute or so. Then activity resumes, You can see what I'm talking about in the vmstat output below: procs memory page disks faults = cpu r b w avm fre flt re pi po fr sr ad4 da0 da1 in sy cs us sy id =A01 0

I should note that I am running 8.1 release on a vanilla cheap HP box (dual-core AMD Athlon, 2 Gb memory, 320 Gb 7200 rpm sata drive). Since 8.2 is imminent, I am wondering if what I am seeing here has been observed before and perhaps there are some improvements in the usb code for 8.2?? /Don Allen
