Curtin has been updated to ignore mdadm asseble errors specifically in the case where curtin has been instructed to wipe a designated device. In the above case, curtin encountered an unexpected return code from mdadm assemble command which is not relevant since curtin is going to wipe the underlying device for re-installation. [Test Case] * Install proposed curtin package and deploy to a machine with a partial mdadm raid array which cannot be properly assembled. PASS: Successfully deploy image with RAID configuration included. FAIL: Deployment fails with the following error: Command: ['mdadm', '--assemble', '--scan'] Exit code: 3 Reason: - Stdout: '' Stderr: u'mdadm: /dev/md/4 assembled from 3 drives not enough to start the array. [Regression Potential] * Users requesting curtin 'preserve' existing raid configurations may be impacted. [Original Description] When deploying a machine in MAAS with a MD setup, deployment fails. Inspection shows that curtin doesn't clean up existin MD devices. On a failed machine I can see in dmesg: [ 22.352672] md/raid1:md2: active with 2 out of 2 mirrors [ 22.730212] md/raid1:md1: active with 2 out of 2 mirrors these are MD devices from previous deployment. Instead of deleting those, curtin tries to create a new one. So /proc/mdstat shows: Personalities : [raid1] [linear] [multipath] [raid0] [raid6] [raid5] [raid4] [raid10] md3 : inactive md1[1](S) md2[2](S) 3125299568 blocks super 1.2 md1 : active raid1 sdd[1] sdc[0] 1562649792 blocks super 1.2 [2/2] [UU] md2 : active raid1 sdf[1] sde[0] 1562649792 blocks super 1.2 [2/2] [UU] unused devices: <none> MAAS's storage config appears to be correct.
