[SOLVED] Mount point for HD not found from live USB

antspants · 2017-10-16 04:01:53

My laptop won't boot, after a forced upgrade. I'm getting a "device not found" error and am getting dropped in to the emergency shell. Digging through the wiki and previous topics, it seems like initramfs (and the fallback) is corrupted, so I have booted up through a usb. So far, so good. However, I am unable to mount the hd to run mkinitcpio. If I try

mkdir /mnt/sda
mnt /dev/sda /mnt/sda

I get

medium not found

.
Can anyone tell me what has gone wrong and how I can fix it?

/dev/sda is your whole disk; you need to mount the partition (sda1 or sda2 etc).

antspants · 2017-10-16 22:27:12

Using ls or findmnt, there's nothing listed under /dev/sda for me to mount. Even if I try to mount sda1 or 2, I get a "device does not exist" error. Is my HD listed somewhere else under /dev?

findmnt finds what's mounted, it is of no use in finding devices. Use lsblk for that.

But in this case both the emergency shell an the live system only detect the live usb filesystem. This leads me to suspect a hardware issue which would also account for the initial symptoms that left you in this situation. Check the cables/connections. Try the drive on another system if you can.

*facepalm* Thanks. Good to know.

Unlikely. It's a laptop - still possible of course - and it happened after a

pacman -Syyu

which got aborted, due to a network issue, so I did it again the next day, after which I got these issues.

Lat weekend on my MacBook -- update to High Sierra, left it running overnight. Laptop hasn't worked since. Can't safe boot, internet boot, install from USB -- anything. Laptops are not infallible. (Yes, a little OT, but it goes to contradict your assumption that laptops can't have hardware failures.)

Anyway, let's see what lsblk shows like Trilby said. If it can't even find your drives, that'd be the starting point.

As shown in the screenshots in my first post, from the emergency shell /dev/sda1 and 2 are confirmed by 'ls' and

cat /proc/partitions

I don't have lsblk in the emergency shell.
However, from the live usb,

lsblk -f

shows only the usb partitions.

Please provide a complete dmesg output from the archiso boot. It's text, so do not post screenshots of it, post the text.

Uuhh-oohhh (There's a severe lack of link resets to make this a cable issue...)

Does the disk still show up in BIOS/UEFI?
In case, try appending "iommu=off" to the kernel parameters of the next archiso boot and pray.

Unlikely. It's a laptop

I don't follow. Laptops don't have hardware issues? They could be *more* prone to such issues as they are moved around.

I have four options to choose from:
Arch iso
UEFI v.1
UEFI v.2
EFI Loader

This is where things get f!#*ing wierd and scary. I tried booting from UEFI v.1 and got a "not found" error. Booting from UEFI v.2 brings up a black screen. I tried booting in to UEFI v.1 again 10 minutes later and it has brought up a "Device Mapping Table" with various hard disks, block devices etc. This certainly suggests a dodgy connection. Apologies to Trilby. The reason I thought it unlikely (not impossible) is because the first time this happened, I did not move the laptop from the time it was working to failed reboot. There must be a very sensitive and light connection somewhere.

Laptop is cactus?

Finally, do I have to remaster the iso to change the kernel params so that I can recover data, assuming I can sustain a connection to the HD?

I meant in the pre-boot settings (pressing DEL, F2 or F11 or so will get you there)
This *might* be a firmware issue (so flashing the disk would revive it) or *might* be a loose connection (if it's detachable) - but the thing could just as much be toast :-(

Check the visibility in the BIOS settings, then check whether you can flash its firmware and otherwise go get a screwdriver ... sorry :-\

Edit: you can edit the kernel parameters right in the kernel command line of the iso disk, but first you need to get some sort of access to the disk.

Sorry about the delay.

I'm not able to get in to the live usb pre-boot settings. Unlike the regular arch setup (which responds to "e"), no menu appears when I start the usb, it just starts booting with a stream of messages. I have tried pressing all the keys and others that you suggested anyway, to no avail. I can't find any documentation suggesting that pre-boot settings can even be modified on a live usb. Thoughts?

seth · 2017-10-24 07:38:39

Unlike the regular arch setup (which responds to "e")

No, that's the boot loader (grub, syslinus, ...) - you're looking for something before that you can access even without any bootable OS (whether on HDD or USB)

=> google or check your motherboards manual.

antspants · 2017-10-24 23:14:26

Thanks for your patience.

This is a Macbook Air, so the "option" key gets me to what I assume are the pre-boot settings. This brings up a screen where I can "Choose Network" and/or select "EFI Boot". When I select EFI Boot, I get a screen with four options, which I listed above (archiso, UEFI, etc).

If I select the archiso, there is nowhere to change the kernel params to "iommu=off", as you suggested.

If I select "UEFI Shell x86_64 v1", I can see "Device Mapping Table" with various hard disks and block devices. Here I have a shell prompt, and "help" or "?" spews out all the commands, but they don't fit on the screen. I can't | less either. I guess these shell commands are built in to the firmware and is unix, not linux, so I may have to ask elsewhere.

seth · 2017-10-25 07:52:13

Be careful what you do in the firmware shell - you can brick the device!

There should be a HW diagnostics tool in the firmware, see https://support.apple.com/en-us/HT201255

antspants · 2017-10-27 03:36:58

Finally able to boot in to my laptop. Got a hint from this topic. All I had to do was edit the kernel params by pressing "e" when "Arch Linux" is selected in the boot options and add

iommu=soft

to the kernel parameters.

After that:
- back up data!

sudo mkinitcpio -p linux

The initramfs was successfully built, but I still got dropped into emergency shell if I omitted the iommu flag.
I also do not get the previous error in dmesg anymore.

[    7.928271] ata1.00: failed to IDENTIFY (INIT_DEV_PARAMS failed, err_mask=0x80)

So then I ran

sudo pacman -Syu

and got a "failed to prepare transaction" error due to a package conflict. By getting rid of the offending package and re-running pacman, I now have a bootable computer! This may have been the original culprit.

I'm still not sure exactly what happened. Either a problem caused by upgrading or a hardware problem or both. I'll assume the worst and open up the laptop.

Thanks for all your help. If anyone can explain what happened, I would be very grateful.

intel_iommu was enabled by default in 4.13.0 - 4.13.4 and caused all sorts of troubles - yours being outstandingly nasty. (if you had said "after updating from 4.12.5 to 4.13.3 [things] suddenly no longer work" that would probably immediately have triggered a link to iommu)
