Can't boot with /dev/sda!

[DJ Charlie]

Ok, I've started the migration of my root and swap onto a USB hard drive, connected through a powered hub, with a 3 amp power supply (been troubleshooting before posting!), BUT, from a fresh boot, the system fails to see the drive every time unless I unplug it, and then plug it back in AFTER everything is booted.

Here's my initial dmesg:

lsusb identifies the drive as:

Code: Select all

Bus 001 Device 008: ID 13fd:1840 Initio Corporation Shintaro SH23SDOCK Hard Drive Docker [INIC-1608L]

The drive works beautifully after I unplug and replug it. Tried 3 different cables, different sockets on the USB hub, etc. Until it shows up reliably at boot, I'd rather not risk changing my boot configuration.

Is it just a flaky drive adapter, or is there a way to fix it?

[MaxK1]

What does lsmod show? You _may_ have to compile your own kernel if a driver needs to be
loaded. But, before going down that road, make sure you have added the following to /boot/cmdline.txt:
root=/dev/sda1 rootwait (Remember that everything in cmdline.txt needs to be all on 1 line!) Also,
after you get it going, edit /etc/fstab to reflect where the / and swap partitions are actually located...

[MaxK1]

My previous post assumes that you have a valid root filesystem (however you installed/copied it) on /dev/sda1....

[RaTTuS]

I know I have to have
CONFIG_USB_STORAGE_CYPRESS_ATACB=y
in my kernel if I want to have the rootfs on the HD using a cheep USB hub
if I don't it will never boot.

so I have to rebuild my kernel on that machine after I do updates that alter it

[remsnet]

Ok, I've started the migration of my root and swap onto a USB hard drive, connected through a powered hub, with a 3 amp power supply (been troubleshooting before posting!), BUT, from a fresh boot, the system fails to see the drive every time unless I unplug it, and then plug it back in AFTER everything is booted.

Here's my initial dmesg:

The drive works beautifully after I unplug and replug it. Tried 3 different cables, different sockets on the USB hub, etc. Until it shows up reliably at boot, I'd rather not risk changing my boot configuration.

Is it just a flaky drive adapter, or is there a way to fix it?

Well you altered the /boot from vfat to ext3 linux partion.
revert that step back to vfat and you may boot

[MaxK1]

I took my Cypress USB/ATA out and popped in a cheapo USB/SATA bridge and 250G hard drive. Of all the adapters I have, that was the only one I was compiling a kernel for. Nice to have all 3 Pi's at the same kernel/firmware level and not have to do an overnight build. It still bothers me that (according to the comments) that the Cypress _should_ have "Just Worked", it required "something" chipset specific
to get poked/prodded/kicked to get it's attention....

[MaxK1]

/boot stays on the SD card, it's only the / filesystem (and swap) you want on /dev/sda!

[DirkS]

How do you come to that conclusion? AFAICS the SD card has the 'normal' partitions and the HD has a linux and a swap partition...

As for the filesystem on the drive, I'd rather get it showing up reliably after booting before I start reformatting it, and moving my system over to it.

[DirkS]

/boot stays on the SD card, it's only the / filesystem (and swap) you want on /dev/sda!

Don't think this is relevant at this point. Looking at the log the HD is not even recognised at startup. As the OP says (and the log seems to confirm this) the HD only shows up when he 're-plugs' it after boot.

Gr.
Dirk.

[thradtke]

BUT, from a fresh boot, the system fails to see the drive every time unless I unplug it, and then plug it back in AFTER everything is booted.

Yes, the drive isn't ready fast enough. There's a workaround you'll find when using the board search functionality.

The boot_delay=32 rootdelay=10 added to cmdline.txt? First thing I tried, sadly.

Increasing the boot delay doesn't help?

[remsnet]

okay , got your point .

Did you updated initrd accordingly to load the USB subsystem´s relevant Modules from initrd ?
Been your Kernel compiled in the hotplug support ?

[DJ Charlie]

Apparently not with those values. Think I should increase the boot_delay?

Running the stock kernel, and what modules do you mean? The drive works beautifully, IF I unplug it and plug it back in, AFTER booting up.

[thradtke]

Apparently not with those values. Think I should increase the boot_delay?

I do. The most efficient way to determine a good value is a binary search.

[MaxK1]

Can you hear the drive spinning up/heads settling within the 10 seconds (or whatever value you chose)? 10 seconds should be enough - I'm pretty certain even my Microdrive will spin up in that amount of time. I don't see any modules listed for the drive in the 'lsmod'...

The drive spins up right away, no problems there at all.

Well,
i ask if you added this modules to initrd:

rt2800usb 13009 0
rt2800lib 47242 1 rt2800usb
crc_ccitt 1465 1 rt2800lib
rt2x00usb 11075 1 rt2800usb

They not required when you _not_ boot from external disk.

They don't show up when the drive IS working either. I think you're off on a completely different track.

[MaxK1]

The Generic USB mass storage driver is built-in so no initrd should be needed for that drive. So, what I would do to see if it is even going to try is to change /boot/cmdline.txt to point at
root=/dev/sda2 rootwait and see what happens.

If it takes off, you're good to go (assuming you have put a valid root filesystem on /dev/sda2, of course!)
If it hangs, the drive isn't being detected. Then it's a matter of figuring out what it needs.
If it carps, the filesystem may not be valid, but at least it tried to mount it.

# 2 is "A Bad Thing(TM)"

All that should do is give us a direction... Make sure you can easily restore your original cmdline.txt... Or use a different card and clone it first...

[stupid_boy]

i boot from sda2 too, some noname external usb 2.5 sata hdd case. only modification i made is in cmdline.txt.
difference with this here is that my partitions are in reverse, first is swap and is 4G in size. can you try to reverse yours?
i have relatively old setup, only updated/upgraded over time. may be you can try this way too.

recently i have problem ( with upgrade, not with boot ) when i removed second partition from SD card, nevermind it seem not used, but this is different story. this lesson lead me to some unusual conclusions.

[MaxK1]

Ooops - My Bad, should be root=/dev/sda1 rootwait.

[DJ Charlie]

No joy. Increased the values double (boot_delay=64 rootdelay=20), same result. Tried setting root=/dev/sda2, same result, had to swap back to my old SD card. The drive spins up. If I plug it in AFTER booting, it works flawlessly.

I'm starting to suspect the USB/SATA adapter now.

[MaxK1]

I wonder if rootwait is the same as rootdelay=nn
