OK, so the test seemed to go ok (aside from my BIOS trying to boot from
my 'data' drives).
- As you suggested I ran the update command on just the boot array,
> sudo grub-install /dev/md0
It correctly identified the two physical drives and updated them both
- The initial boot (still both drives) was fine. But then it hung on shutdown?
Tried another boot-and-shutdown and this time it shutdown ok.
- 1st test boot (with drive #2 removed). There was the expected 2-min delay
before prompting to boot degraded. The prompt timed-out before I could finish
reading the screen so I unintentionally did the "Answer no" test?
Rebooted, waited, then entered Yes and it booted normally.
- 2nd test boot (with drive #1 removed). Same behavior as previous test.
- 3rd test boot (both drives reconnected). Booted on drive #1 and was able to use
'mdadm --add' command(s) to restore both arrays successfully.
- is there a way to simplify the message screen? Maybe add section headers so that
you can immediately see what each section is about.
- does the prompt need to have a timer?
- is there a single command that could be entered at the Busybox prompt to
manually initiate the proper boot-as-degraded script? If so, can the system display it after
you select 'No' (or time-out) ?
- why doesn't Partition Editor (Gparted) recognize 'md' devices? Probably unrelated to this backport
but you seem like the person to ask! On this 8.04.1+ system my Gparted v0.3.5 says,
"kernel is unable to re-read the partitiontables on /dev/md0"
If you're not supposed to use Gparted to edit raid devices, it would be nice if it directly told you so
and maybe offered to let you view them in read-only mode.
- There's a typo in one of the modules. When I shutdown I saw a command-line message,
"Network Manager: caught terminiation"
Finally, after I ran these tests (yesterday and today), I was prompted by Update Manager that there was another update for 'initramfs-tools' and 'mdadm' -- was that from you? I didn't want to install them until I knew they weren't a wrong version. They didn't have any Description or Version info in Update Manager, but Synaptic identified them:
- initiramfs 0.85eubuntu39.3~ppa4
- mdadm 2.6.3+200709292116+4450e59-3ubuntu4~ppa4
Are they new updates that you want me to re-run the test with, after
SRU: Backport of Boot Degraded RAID functionality from Intrepid to Hardy
