Cannot use usb-storage initrd module.

My laptop broke and now I use my formerly internal hard disk as an

external hard disk in another laptop. It booted fine but I could not

reconfigure maybe because Guix checks for a wrong spelling of the

usb-storage module.

When I pulled

1458f768c1049812166228b8526128b199518e50

and reconfigured I was told to use

(operating-system

...

(initrd-modules (append (list "uas" "usb_storage")

%base-initrd-modules))

However the module is apparently called usb-storage with a hyphen, the

path is

/gnu/store/9idmpc60bgah6cy6s0k739kpj9qz50qc-linux-libre-4.16.13/lib/modules/4.16.13-gnu/kernel/drivers/usb/storage/usb-storage.ko

Possibly for this reason I got an error

But when I use

(operating-system

...

(initrd-modules (append (list "uas" "usb-storage")

%base-initrd-modules))

then I get an error because I should spell it usb_storage.

Eventually I changed gnu/system/mapped-devices.scm to replace

(device-module-aliases device)))))

(unless (every (cute member <> linux-modules) modules)

by #t. Then it successfully reconfigured.

I tested again Guix commit 19b662ea7c53a28270a783f10ca033d8c9d2a954

today and it is still broken.

merge 31598 31714

Today it seems I hit this bug.

The last days I've been upgrading this machine with guix pull, and have been

booting and reconfiguring fine until a few hours ago.

Also, sorry about formatting.

My config contained:

(initrd (lambda (file-systems . rest)

;; Add a kernel module for RAID-0 (aka. "stripe")

;; and RAID-1 (aka. "mirror").

(apply base-initrd file-systems

#:extra-modules '("raid0" "raid1")

rest)))

And I got an error from guix system reconfigure/build:

<unknown location>: error: you may need these modules in the initrd

for /dev/sdg2: uas usb_storage

hint: Try adding them to the `initrd-modules' field of your

`operating-system' declaration, (initrd-modules (append (list "uas"

"usb_storage")

The machine has the OS on a usb stick because all the internal SATA drives

are RAID and I prefer to separate them. This machine has been configured like

this for a long time.

After following the recommendation (and finding the module in store is

actually named usb-storage.ko) I end up with the following config snippet:

(initrd-modules (append (list "uas" "usb-storage" "raid0" "raid1")

%base-initrd-modules))

(initrd (lambda (file-systems . rest)

;; Add a kernel module for RAID-0 (aka. "stripe")

;; and RAID-1 (aka. "mirror").

(apply base-initrd file-systems

#:extra-modules '("raid0" "raid1"); "uas" "usb-storage")

rest)))

This works if I use --skip-checks. But with checks it gives me the same error

as above, changing the initrd-modules line to:

(initrd-modules (append (list "uas" "usb_storage" "raid0" "raid1")

Gives the following error:

Hello,

Tonton <tonton@riseup.net> skribis:

[...]

The problem was that the hint would specify “usb_storage”, which is the

correct module name but not the right *file* name (it’s “usb-storage”,

notice the hyphen.)

This is fixed in commit fcd068e984078ab74c6842af2525bf88096cd262, which

takes a sledgehammer approach: it tries hyphen and underscore file

names, such that ‘initrd-modules’ can contain either “usb_storage” or

“usb-storage”.

Thanks,

Ludo’.
