bug#31714: Cannot use usb-storage initrd module.

bug#31714: Cannot use usb-storage initrd module.

[pelzflorian (Florian Pelz)]

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.

                                %base-initrd-modules)))



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

  (when aliases
    (let ((modules (delete-duplicates
                    (append-map (cut matching-modules <> aliases)

      (unless (every (cute member <> linux-modules) modules)
        (raise (condition
                (&message

                                  device modules)))
                (&fix-hint
                 (hint (format #f (G_ "Try adding them to the

by #t.  Then it successfully reconfigured.

I tested again Guix commit 19b662ea7c53a28270a783f10ca033d8c9d2a954
today and it is still broken.

bug#31714: Cannot use usb-storage initrd module.

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:

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’.
