Additional HDDs Are Absent in Custom Kernel (Linux 3.19.8)

AGT · 2015-06-19 03:08:03

Hello.

I compiled myself Linux 3.19.8 using a base configuration from another official, close (I forgot which one exactly (3.x)) version.
All seems well so far, but as I have 3 HDDs, all are detected in the official versions (latest and LTS) of the kernel, but in my version, only the one on which the root volume is present is detected.

How could I debug the problem?
I could provide the configuration if needed.
Generally speaking, I included as many device drivers as possible as modules, and made some other tweaks.

Thank you.

What sort of filesystems? Output of fdisk -l and your fstab? Are the required modules loaded? What is in dmesg and your journal? etc...

Also please tell us why you are compiling a custom kernel. What are you trying to accomplish by doing this?

They are both NTFS (Windows 7 is installed on one and the other one holds data).

fdisk -l does find all of them.
I have not set them up to automount with fstab.
I am unaware of which modules I should load.

I was worried when I saw that DE apps like GNOME Disks and MATE Disk Utility do not show any devices at all, not even the root. Caja shows only the root volume.

The journal tells that all of the disks have been detected.
I included here what I think is relevant about the disks from this morning's startup:

Initially, I compiled 4.0.3 and then 4.0.5 to enable the user namespace to allow Chromium to properly run as root.
Secondly, I noticed that 4.x is slightly unstable with hostapd on my servers, so I took and compiled the latest 3.x version on my laptop, as I thought that that would be stabler. My servers would follow, if the resulting compiled kernel performs acceptably.
Finally, this allows me to tweak some settings along the way.
But I am not an expert at compiling kernels: each time I compiled one, for example, there is verbose output when booting between the normal services' startup messages, in this format: "[ SequentiallyIncreasingNumber] Message". ...I had modified the configuration only minimally from the default one, and the boot command line that I used was the same. This is another problem which I don't know how to solve. Please do tell me if you would know!
In general, the only was that I see how to debug a kernel configuration is to recompile it with only one option differently set; this would confirm if that option is responsible for the problem you would be experiencing. Would there be another way?

Thank you!

In that case, have you tried ntfs-3g which is in userspace and not in the kernel...

AGT · 2015-06-20 11:36:42

It is already installed.
The official versions of the kernel work; only mine does not work: it doesn't even show the disk where the root volume is. Because only GUI programs do not show any disks, while CLI programs do (I can mount /dev/sd* devices), I am thinking that the problem may be between the GUI apps and the system, which might not provide access to the disks by these apps.

Have you compared the kernel modules that are loaded by the ARCH kernel and ensured those very same drivers are either built into your kernel or are modules (and that that those modules are loading) in your kernel?

AGT · 2015-06-21 02:55:23

I lsmod the 4.0.5-1-ARCH, 3.14.44.1-lts-ARCH, and my own, and modprobed the missing modules.
It didn't have any (apparent) effect.
I plugged in a USB flash drive to test if it would be recognized, and it was detected in Disks and Disk Utility.

Thanks for all your suggestions.
