Package: mdadm

Dear Maintainer,

* Currently, mounted raid0/md-linear arrays have no indication/warning when one or more members are removed or suffer from some non-recoverable error condition. The mdadm tool shows "clean" state regardless if a member was removed.

* The patch proposed in this SRU addresses this issue by introducing a new state "broken", which is analog to "clean" but indicates that array is not in a good/correct state. The commit, available upstream as 43ebc910 ("mdadm: Introduce new array state 'broken' for raid0/linear") [0], was extensively discussed and received a good amount of reviews/analysis by both the current mdadm maintainer as well as an old maintainer.

* One important note here is that this patch requires a counter-part in the kernel to be fully functional, which was SRUed in LP: #1847773.
It works fine/transparently without this kernel counter-part though.


In Ubuntu, the attached patch was applied to achieve the following:

  * Introduce "broken" state for RAID0/Linear in mdadm (LP: #1847924)


Thanks for considering the patch.
