libbd_mdraid.so.2: cannot open shared object file

[themusicgod1]

Had some (probably unrelated?) trouble typing input into login console, and went looking through /var/log/syslog :
found

Seems to give this warning every time I boot.

Status changed to 'Confirmed' because the bug affects multiple users.

Well, I too am getting these errors, every time I boot up Ubuntu Mate 19.04 x64:

apparently Adding libblockdev-crypto2 and libblockdev-mdraid2 will solve this

Same issue:
udisksd[1920]: Failed to load the 'mdraid' libblockdev plugin

Installing libblockdev-mdraid2 pulls in mdadm which is not a solution on systems which don't implement RAID.

On such systems, udisksd should not try to load the 'mdraid' libblockdev plugin.

Confirmed on focal.

[Sebastien Bacher (seb128)]

Is there anything really failing or is that just a warning in the log?

[themusicgod1 (themusicgod1)]

Seems to be just the warning in the log for me

[themusicgod1 (themusicgod1)]

hasn't come up in awhile though

[Steph B (64bitguy)]

Had the issue in Linux Mint 20.1 and resolved by installing:

libblockdev-mdraid2

[xcom (xcom)]

i had the same issue.

[Ole Jon Bjørkum (olejonbj)]

Same on Ubuntu 20.04 both GA and HWE kernel.

Sure, it just takes this command to find which package has it:

$ apt-file search libbd_mdraid.so.2

And get "libblockdev-mdraid2", which does "fix" it, but I DON'T need it. Depends on packages I don't need, MOST don't need:

$ apt show libblockdev-mdraid2

Depends: libblockdev-utils2 (>= 2.20), libbytesize1 (>= 2.1), libc6 (>= 2.27), libglib2.0-0 (>= 2.42.2), mdadm (>= 3.3.2)

However it's the same on Raspbian for the Raspberry Pi, so it's more of a Debian problem. And installing that package then wants exim4 and all... A mail server?? For a library?

[David H. Brown (dave-davidhbrown)]

I encountered something very similar to this issue (maybe even this issue?) when my docker containers could not start (using snap on Ubuntu 20.04.3 LTS under VirtualBox with a Windows 10 host). Similar to others, `sudo apt install libblockdev-mdraid2` seems to have fixed it.

In case these log lines are useful context, they came from `sudo grep fail /var/log/syslog` (just trying to filter out some of the noise and I suspect that the devmapper/containerd/cni bits are not directly related):
