Description PC LX 2018-04-23 19:39:59 CEST

Description of problem:

The dm-cache.lo.xz kernel driver is missing from the Mageia-6-x86_64-DVD.iso image.

The /proc/config.gz indicates that dm-cache is configured as a module but the kernel module is not in the iso.

It would be great if this could be fixed in the Mageia 6.1 isos.



Version-Release number of selected component (if applicable):

$ cat Mageia-6-x86_64-DVD/DATE.txt

$ cat Mageia-6-x86_64-DVD/Mageia-6-x86_64-DVD.iso.sha1
03c496389fd39b80107077828a066163d8c38c17  Mageia-6-x86_64-DVD.iso



How reproducible:

Always.



Steps to Reproduce:
1. Boot a system or virtual machine from the Mageia-6-x86_64-DVD.iso image.
2. Wait for the graphical installer to start.
3. Go to the second console (tty2) using CTRL+ALT+F2 (RCTRL+F2 in VirtualBox).
4. Use the command "find /lib/modules -ipath '*dm-cache.ko*'" and see that no files are found.
5. Use the command "gzip -d -c /proc/config.gz | grep DM_CACHE" and one of the output lines is "CONFIG_DM_CACHE=m" indicating that dm-cache is configured as a module.

See attached image for the output of steps 4 and 5.

Martin,
You need to add mga#22946 in the commit message to have an automatic post in bugzilla. ;)

Ah, I'd forgotten Thomas's fix came in two parts. The second part had the mga#22946 in the commit message:

http://gitweb.mageia.org/software/drakx/commit/?h=distro/mga6&id=a0a3d5a08d5e3a8e8a13173579393acb7fdac226

When I pushed my git commits, I got a sequence of error messages about failing to post to Bugzilla (for other bugs as well as this one). So it did try...

Comment 6 Martin Whitaker 2018-12-19 21:37:56 CET

I've just confirmed the dm-cache module is on the Mageia-7-beta1-x86_64 ISO.

Note that I needed to use 'find -L' because /lib/modules is a soft link.

Resolution: (none) => FIXED
Status: NEW => RESOLVED
