Hi, on one of my QNAP TS-419P+ NASes running Debian 8.x stable, I started getting smart errors on one out of the four SATA drives, so I pulled the drive and swapped it for a brand new one.
The system didn't boot any more. I found bug 784070 and particularly message 109 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=784070#109 with a hack for /usr/share/initramfs-tools/scripts/local-top/mdadm that forces boot to continue with incomplete mdadm arrays. This worked perfectly; fortunately I could insert the old broken drive, boot up, log in, change the script, run "update-initramfs -u", shutdown, swap the drives, reboot and fdisk+mdadm --add the new drive. I guess without the patch, the NAS is booting to an emergency console, but there isn't any easily accessible console to interact with. Is there a chance that something like this can be applied for the next point update of Debian Jessie stable? I'm concerned that a local modification to a script like this might be overwritten at any time, forgotten, and then be left with an unbootable system the next time something like this happens - especially if the faulting drive doesn't play ball allowing a quick re-application of the patch. Thanks.
