mdadm: Cannot get exclusive access to /dev/md127
by Rich Emberson 01 Feb '15

01 Feb '15

I've got a two disk raid and I want to it and convert the disks to some non-raid usage. The raid was never used and has no data. Also, the raid disks are encrypted along with the rest of the disk in the machine. When I try to stop raid I get the following: # mdadm --stop /dev/md127 mdadm: Cannot get exclusive access to /dev/md127:Perhaps a running process, mounted filesystem or active volume group? Googling about this there are a number of folks hitting this problem over a number of fedora releases. Sadly, I could not find any fix. For some the solution (nuclear solutions) was to use a different linux distro or reinstall. I've got a lot of data on other disks on this system and really don't want to use a nuclear solution.

I have a smart TV (Sony Bravia) and can use Android Cast Screen from my phone or tablet to see content. Apparently it also works with the Apple equivalent. Is there a way to do this from my F21 desktop? poc

Old Kernel Modules Directories not Cleaned up
by Stephen Morris 01 Feb '15

01 Feb '15

Hi, DNF is currently configured to keep 3 kernel versions, consequently when I exceed that number of kernels it automatically uninstalls the oldest kernel, which I don't have any issues with, but what I do have an issue with is when these uninstalls are done it does not clean up the /lib/modules directories, they are left lying around. I had to delete a dozen of these directories this morning manually, why are these not removed when the associated kernels are removed? I didn't check what was in these directories, but I do have the nvidia and virtualbox kernel drivers installed as well, is it possible the removal of these when the associated kernel is removed is not cleaning up properly? regards, Steve

Re: fedora 21 booting error with 3.17 & 3.18 kernels-SOLVED- still need info
by Paul Cartwright 01 Feb '15

01 Feb '15

I finally let the boot sequence error out, took about 5 minutes. I got this line: Dracut-initqueue[283] Warning: Cancelling resume operation. device not found. then the next line showed the UUID, ending in c063. That was the OLD swap partition. I rebuilt the swap partition, did the swapon, and added that UUID to /etc/fstab. Still errored out with same error. I removed the 3.18.3-201 kernel & headers & module, reinstalled them, and now it works. where is that old swap info kept, if not in /etc/fstab?? I grepped for c063 in /boot and found entries in System.map-3.18.3-201... but I am not sure it was the actual swap partition. > running fedora 21 x86_64 > I was redoing my drive partitions, reran grub2-install, and now I get > stuck, and the boot won't complete when I select any 3.17 or 3.18 > kernel.

Annoyances with mate DT
by JD 01 Feb '15

01 Feb '15

For a while (like a few weeks), mate was saving the apps running on the DT when I shutdown the system, and they would be auto started on reboot. Slowly, some apps no longer get started. This behavior first manifested 2 or 3 months ago when the mate-terminals would no longer be started on reboot. Then it was ktorrent. Now, added to that is smplayer. I had raised a bug with mate, but the bug report was rejected. I am on the verge of dumping Mate altogether. Cinnamon is just not mature enough, and I literally detest gnome3. It does nothing that I want or like. Hope that future fedora users who want to switch to mate might see this and decide if they still want to run mate.

kernel-debug-devel?
by Tom Horsley 31 Jan '15

31 Jan '15

Random curiosity here: Why (on fedora 21) does the kernel-debug-devel rpm want to be installed? If I do a yum erase of it, it goes away without removing any dependencies at all, yet if I do a yum update after that, it wants to reinstall it again despite the fact that nothing depends on it :-).

DRM MM Objects?
by Andy Blanchard 31 Jan '15

31 Jan '15

Just upgraded a box at home to new hardware with embedded Intel graphics (i5 Haswell), did a clean install of Fedora 21, and while poking around trying to fix a few issues while rebuilding my config spotted something I've not noticed before. With KDE running "lsof" lists over a thousand entries like this: Xorg.bin 659 662 root DEL REG 0,4 16016 /drm mm object Xorg.bin 659 662 root DEL REG 0,4 16011 /drm mm object kwin 964 zocalo DEL REG 0,4 38725 /drm mm object kwin 964 zocalo DEL REG 0,4 19275 /drm mm object QProcessM 964 986 zocalo DEL REG 0,4 19277 /drm mm object QProcessM 964 986 zocalo DEL REG 0,4 47240 /drm mm object These are the only three processes that appear to own these files, and the number of entries appears to fluctuate as windows are opened/closed, and other GUI events happen. A Google search comes up with a bunch of stuff about memory leaks from a few years ago, plus some documention on Kernel memory management, but I couldn't find anything that explains what these "/drm mm object" entries are, whether this is normal behaviour, or if there is potentially a problem. Any ideas? -- Andy The only person to have all his work done by Friday was Robinson Crusoe
