Netgear r7800 misses kmod-usb-storage #2198

Closed smoe closed 3 years ago

smoe commented 3 years ago

The BOINC package needs extra USB storage to function. This works nicely on the OpenWrt snapshots I tried so far, but my BOINC backport to 19.07 for my gluon router I cannot get to run because of kmod-usb-storage missing for my Netgear Nighthawk r7800. This looks like an upstream issue to me since the decision to include the package is device-specific, but you may want to direct me on where to direct any such patch.

What I was expecting was to have kmod-usb-storage available as a module, such that I could

# opkg install kmod-usb-storage_4.14.209-1_arm_cortex-a15_neon-vfpv4.ipk
Installing kmod-usb-storage (4.14.209-1) to root...
Configuring kmod-usb-storage.

to see /dev/sda as in 

# ls -l /dev/sda
brw-------    1 root     root        8,   0 Apr 10 00:11 /dev/sda

but by default, the USB stick is found and displayed via lsusb, but no offered as a device. For other platforms USB storage is available, though.

I am not exactly sure about what is the right thing to do about it. Since this is all close to the kernel, I presume that the module is best offered by the same individual who also compiles the kernel? I have hence prepared

and also did the same to a linksys wrt3200acm.

The USB drive was offered as a device immediately upon the installation of kmod-usb-storage.

I could then install cfdisk to repartition, the e2fstools to give me a filesystem, except that /proc/filesystems then informed me that there is no kmod-fs-ext4 to explain the error upon mounting the device. I then analogously helped myself with the installation of kmod-fs-ext4 but this was again only available via my own build, not to be downloaded.

Is there a way to ease the process for adding an USB stick to gluon? Or is this for every community to provide independently?

Many thanks! Steffen

you can add packages to devices or targets much easier using the site.mk file, see for example our site.mk : https://github.com/tecff/site-ffa/blob/experimental/site.mk if this helps, please close your issue, at least i don't know what to do else here...

Thank you for the pointer, @rotanid. I will do so, but maybe we could continue to discuss on this then closed issue what OpenWrt should change about it - they should know what machine has USB ports and which ones have not and then come up with these packages built upfront, right?

@smoe openwrt images contain usb for this device, of course, but not the storage kmod. https://git.openwrt.org/?p=openwrt/openwrt.git;a=blob;f=target/linux/ipq806x/Makefile;h=69d3aa1e569d79a9436bf14035063986cc12c5e4;hb=HEAD#l21

@rotanid If the philsophy is that any USB device should optionally be allowed to serve some storage purposes - then this would be a patch against OpenWrt, right? Should we then not synchronize any such patch with your site.mk? This would then live as a gluon-patch against OpenWrt and as a pull request for OpenWrt.
