Mount 2 TB USB storage device
I have posted this before.....however no reply or help yet!!
please....if anybody has suggestions...I had to resort to FTP files transfer...took 5 days!!
Hello all,
I have been trying for the past week to mount a 2 TB usb storage device that I built (VENUS box with 4x 500 gb). It shows up when I type
cd /dev/rdsk
ls -l c*0 | grep usb
I then tried to mount it with this command (vold turned off)
mount -F pcfs /dev/dsk/c4t0d0s0:c /mnt
it says no device or address.....
so I typed iostat -En
got this
usb_sd1 Soft Errors: 3 Hard Errors: 0 Transport Errors: 0
Vendor: Product: Combine 4HDD0702 Revision: 1278 Serial No:
Size: 2000.43GB <2000431448064 bytes>
Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0
Illegal Request: 3 Predictive Failure Analysis: 0
I need HELP!!!
Thanks
Jared

I don't have the answer, exactly, but I'm guessing you don't have a slice 0 or slice 2 when you prtvtoc /dev/rdsk/c4t0d0s0
I thought the way you had to do this was with rmformat (for removeable media - which is what usb is considered) - if you needed to format the device
or
use fmthard to populate the vtoc on the disk
anyone with the final answer on this, feel free to chime in
I was going to test this on a little thumb drive today on a solaris 9 box, could report back later (I'm worried to see how long a rmformat would take to actually format a 500GB USB2 or firewire drive - please don't talk to me about throughput, I'm talking about how wonderful or not the rmformat command is at large media)
Thanks!

ok, then what does the prtvtoc /dev/rdsk/c4t0d0s2 show?
I just tried this on my usb drive, I did have to mkfs -F pcfs, as docs.sun.com sez, with -o nofdisk,size=<desired size from prtvtoc>
and sure enough, it was fine
I know it doesn't help you as you already have your fs, but it should give hope that this *should* be possible

actually, I had the thought of bringing my thumb drive back to my Win XP workstation, did a looksee at the drive and sure enough it shows FAT for the filesystem layout.
So I reformatted it FAT and put it back on the Sparc, didn't have to do anything other than mount -F pcfs /dev/dsk/<device>s0 /mnt
and it came up just fine
I repeated this test successfully with FAT32, though on my small thumbdrive, I don't know the OS limitations of Solaris and it's FAT32 implementation (for max filesize)
hth
oops - thanks for the note Darren - I was too busy running back and forth testing to do a refresh on my screen :S

just to complete my postings for the day - I thought I also saw something that USB 2 standard wasn't *fully* supported in Solaris until 10
that would make accesses to that 2TB drive absolutely maddening as transfer rates would downstep
I'm noticing about 500KB/sec transfers on my solaris 9 machine - from a tmpfs filesystem , single 100MB file to a thumb drive
sigh
