This owner has one tower that has 3 different drives and each drive has it's own Linux os.
Mint 19.1, Debian 9 and MX-18:-

After installing Mint and MX-18 there is now the error message:

Code:

mdadm:No arrays found in config file or automatically

Raid arrays were not set up on this machine.

Running:

Code:

mdadm --detail --scan --verbose
and mdadm --examine --scan --verbose

Returns nothing.

Should it be ok to delete the mdadm.conf file?

After many days of reading through pages of google searches it's become clear what the error:

Code:

mdadm:No arrays found in fonfig file or automatically

is all about.

The etc/mdadm/mdadm.config file is simply for creating and managing Raid arrays.
Since I do not have any Raid arrays set up I'm thinking about removing the mdadm.config file all together and see if I still get the error at boot up.

I've looked for the mdadm file on Mint and MX-18 and that config file does not exist. I don't know for sure if this file was automatically generated or somehow was created due to an update.

I'll have to find out with certainty over the next several days and more searching/reading if removing that file is going to be an issue.
I suspect that removing that file won't be a problem as there aren't any Raid arrays set up.

Rename it to mdadm.config.bac and reboot. At least it can be restored if actually needed. The /etc/mdadm directory don't exist on my Debian testing. Nor is the mdadm package installed on mine, maybe uninstalling the package altogether.

Oh!
I tried a mock install of mdadm and there are 14 dependencies, so perhaps it was installed as a dependency for something else on yours.

Code:

jo@Willy:~$ apt-cache rdepends mdadm
mdadm
Reverse Depends:
  libblockdev-mdraid2
  zfs-test
  udisks2
  systray-mdstat
  libguestfs0
  grub-common
  backupninja
  grub-legacy
  forensics-extra
  fai-setup-storage
  dracut-core

The fact that it's not on your Debian Testing machine makes me suspicious that something may not of been right with a recent update or upgrade:-

I can't get to that machine right now so.........
I'll rename it when I can, reboot and let you know what happens.

The list of packages in my last post for the apt-cache reverse depends shows which packages may be installed that needed mdadm as a dependency.

grub common is an important pkg so I'll rename the mdadm file and see what happens.
Thanks for listing the dependencies.

Do you think Brains that there is a chance renaming that config could cause Debian not to boot?

Brains · 02-19-2019, 10:20 PM

I have grub-common installed, so likely won't be an issue. Which also suggests the reverse depends is not entirely accurate, I also have udisks2 installed but none of the others.

Renaming that file fails with error with or w/o elevated privileges.

Code:

rename mdadm.conf mdadm.conf.bac /etc/mdadm/mdadm.confBareword "mdadm" not allowed while "strict subs" in use at (user-supplied code).

Any thoughts? What am I missing?

Code:

root@Willy:/home/jo# aptitude install mdadm
The following NEW packages will be installed:
  exim4-base{a} exim4-config{a} exim4-daemon-light{a} guile-2.2-libs{a} libgnutls-dane0{a} libgsasl7{a} 
  libkyotocabinet16v5{a} liblzo2-2{a} libmailutils5{a} libntlm0{a} libunbound8{a} mailutils{a} 
  mailutils-common{a} mdadm psmisc{a} 
0 packages upgraded, 15 newly installed, 0 to remove and 0 not upgraded.
Need to get 10.4 MB/11.1 MB of archives. After unpacking 59.6 MB will be used.
Do you want to continue? [Y/n/?] n
Abort.
root@Willy:/home/jo#

Here's a suggestion:

The code above shows the 14 dependency packages that would get installed if I were to install mdadm. If you run command: apt-get remove mdadm and these are the only other packages that would need be uninstalled also, means mdadm is not installed as a dependency for something else, it may have been installed as a "suggested" or "recommended" package, which in turn means you don't really need it. As long as the list to be removed only contains these or some of these packages, you'd be safe to remove it. It should ask for confirmation before going ahead. If you have synaptic installed, it'll do the same.

If it returns saying there are other packages not in the list above that will need be removed, then you will know which packages depend on it and can decide then whether you want to go ahead or not.

Not sure if I want to rm mdadm and it's dependencies or not.

First I'm going to run dpkg -L and see if it's already installed.

The good news is Debian still boots it just takes a while because the error shows about 20 times in tty before taking me to the log in.

Another thing I'm going to try is to boot to a Live Linux CD and try to rename that file. I'll see what that get's me:-

Ztcoracat · 02-22-2019, 03:28 PM

Well, mdadm is already installed:-

I'll try renaming that file with the Live Linux Mint CD and see how that goes and let you know.

Ztcoracat · 03-04-2019, 06:25 AM

I haven't forgotten about this thread.

Life has been very busy.

mv should work too.

So, you're just trying to stop mdadm from reporting it's findings at boot?

If you don't want/need it just remove the package.
