Bug Description
[ Impact ]
* An explanation of the effects of the bug on users and
* justification for backporting the fix to the stable release.
* In addition, it is helpful, but not required, to include an
explanation of how the upload fixes this bug.
=>The customer will fail to remove NVME disk from container when they use "-r" option. if the fix can be backport into stable release , the users will remove successfully, no matter useing option '-r' or '--remove'.
[ Test Plan ]
To reproduce the issue:
1. Fresh install Ubuntu server 22.04.3
2. Create a container via below command:
# mdadm -C /dev/md0 /dev/nvme0n1 /dev/nvme1n1 -n 2 -e imsm
3. It will fail during removing a device from container /dev/md0
# mdadm -r /dev/md0 /dev/nvme0n1
mdadm: /dev/nvme0n1 does not appear to be an md device
# mdadm /dev/md0 -r /dev/nvme0n1
==> No output
It can pass via "mdadm --remove /dev/md0 /dev/nvme0n1"
[ Where problems could occur ]
* Think about what the upload changes in the software. Imagine the change is
wrong or breaks something else: how would this show up?
* It is assumed that any SRU candidate patch is well-tested before
upload and has a low overall risk of regression, but it's important
to make the effort to think about what ''could'' happen in the
event of a regression.
* This must '''never''' be "None" or "Low", or entirely an argument as to why
your upload is low risk.
* This both shows the SRU team that the risks have been considered,
and provides guidance to testers in regression-testing the SRU.
