[Bug 1487365] Re: Ubuntu14.04 .3 RAID installation fails on firestone

[Launchpad Bug Tracker]

This bug was fixed in the package partman-prep - 27ubuntu1.14.04.1

---
partman-prep (27ubuntu1.14.04.1) trusty; urgency=medium

  * Better handle PReP partitions created for RAID installs (or in other cases
where there are multiple partitioning passes): (LP: #1487365)
- Check filesystem too for a valid PReP partition, in case method was wiped
  in a previous run of partman.
- Set filesystem to prep in init.d/prep.
- Remove mountpoints file when setting up a prep partition.
- Never write the prep flag if we're working on a partition for which the
  parent device is a mdadm array.
- Enforce the fact that the PReP partition can't be on RAID; also update
  the template accordingly.

I verified this on Trusty w/ apt-setup/proposed=true.
The installation finishes fine (no errors on grub-installer), and the system 
boots fine.
Marking verification-done.

Installation instructions for Software RAID have been documented in the
SoftwareRAID [1] wiki page, and linked from the ppc64el wiki page [2].

[Bug 1487365] Re: Ubuntu14.04 .3 RAID installation fails on firestone

[Mathieu Trudel-Lapierre]

** Description changed:

+ [Impact]
+ Users installing on ppc64el with RAID enabled, doing manual or guided 
partitioning are unable to complete the installation because the multiple 
passes of partitioning required to apply the initial partitions on disk (PReP 
partitions and all) and the next set of partitions on RAID or LVM cause the 
initial PReP flags to be lost.
+ 
+ [Test case]
+ 1) Start installation on a ppc64el system with two or more disks.
+ 2) Use manual partitioning to add a PReP partition on one of the disks. It 
should have a size of 8MB, at the beginning of the disk. It can be followed by 
free space or a single partition to be used as space for RAID.
+ 3) Create a RAID volume, using RAID1 (2 partitions, 0 spaces), add the RAID 
partition previously created and the free space from another disk.
+ 4) End partitioning, confirming everything.
+ 
+ The installation should complete successfully.
+ 
+ [Regression potential]
+ This is limited to the handling of PReP partitions, so only applies to 
ppc64el systems. Possible regressions may be failure to allow a valid setup of 
partitions while preparing the install on ppc64el, or failure of the 
installation on an invalid (but not immediately detected) partition setup, at 
the point where grub-installer will try to install the bootloader on the system.

  I'd suggest to either involve our grub2 guy (not sure if available), or
  mirroring to Canonical.

[Mauricio Faria de Oliveira]

@mathieu-tl

This important part of the message has faded in the long comment..

Can this bug be targeted for 14.04.4?

The changes are contained w/in the partman-prep package, which affects
only ppc64el/powerpc, and it looks like a scenario/path that hasn't been
exercised often previously (haven't seen other bug reports). So, I
suspect that, if tried at all previously, it'd be likely to fail (ie,
this bug), so little there's little regression potential.

Thanks!

Hi Canonical @mathieu-tl,

Here's a patch for partman-prep for basic support to Software RAID1
devices.

- It allows for manual and guided partitioning with a PReP partition in one of 
the component devices (not in the RAID array, which is currently not support by 
grub2), which is enough for our needs at this time.
- The current limitation is, for guided partitioning only, after the partitions 
are created in the RAID device, it's required to select the PReP partition in 
the component device (and just exit w/ Done setting up this partition), to make 
sure the 'method' file contains 'prep' (autopartitioning renames that to 
'method-old', and I didn't find a safe/quick method to rename that back in the 
correct PReP partition... ideas welcome :- ).

This is the error fixed for Manual partitioning (see patch):

~ # tail /var/log/syslog
<...>
<...> clear_partitions: Considering /,/dev/sda1. 
<...> main-menu[1679]: (process:12610): mount: mounting /dev/sda1 on 
/tmp/tmp.VVjm38 failed: Invalid argument
<...> main-menu[1679]: (process:12610): umount: can't umount 
/tmp/tmp.VVjm38: Invalid argument
<...> main-menu[1679]: (process:12610): mount: mounting /dev/sda1 on 
/mnt/tmpmount failed: Invalid argument

Tested with Trusty jan/12 daily build, in this scenario:
- 2 disks (sda, sdb)
- PReP partition in sda1
- Software RAID1 in 'sda free space #2' (after PReP partition) and 'sdb free 
space #1' (entire disk)

... with the following partitioning methods:
1) manual partitioning
2) guided partitioning
3) guided partitioning w/ LVM 

All have successfully installed and booted.


For reference, the relevant parts of the installer's syslog, and post-
install/post-boot partitions/LVs used:

[Bug 1487365] Re: Ubuntu14.04 .3 RAID installation fails on firestone

[Mathieu Trudel-Lapierre]

There may be a way to make this work, but only for RAID mirrors (level
1), in a particular version of the mdadm format, since both disks should
have the same layout and look identical to non-mirrored disks, but it
needs more work.

In the meantime, it seems like the supported partition layout should be
appropriately enforced by partman-prep on installs. So, indeed one will
have to make sure not to install a prep on a RAID device, but there
isn't an automated partitioning setup which allows this to be done
automatically -- it always either involves a couple of steps to set up
RAID and then the partitioning on top, or full automation via preseed
(which would be something out of the control of the installer -- up to
the user to fix).

Correct, this is currently not supported; I argue that it should be, though
extending grub to support this is not necessarily the top priority.

[Bug 1487365] Re: Ubuntu14.04 .3 RAID installation fails on firestone

[Mathieu Trudel-Lapierre]

The obvious initial step for this is to enforce the partitioning scheme
that we do support (ie. PReP can't be on RAID), and I've been testing a
partman-prep update with this.

There's also a big part in grub-installer; I'm preparing a proper fix
for this there, pending testing to make sure the firmware understands
the way the disks are set up in the case of RAID 1 (because we can't
support other RAID levels).

[Bug 1487365] Re: Ubuntu14.04 .3 RAID installation fails on firestone

[Steve Langasek]

There are multiple related issues here.

 - partman-md does not support assembling a RAID1 array out of a set of whole 
disks; it only supports assembling an array out of partitions.  It *should* 
support using whole disks, so that you have the option of partitioning the RAID 
array and having those partitions show through on the underlying block devices 
in a way that is meaningful to the firmware.
 - in the absence of such support in partman-md, users are led down the garden 
path *thinking* they're creating arrays out of the disks when they're actually 
creating full-disk partitions on the component disks and RAIDing those.  
partman-prep should warn the user *early* (i.e., at the partitioning stage) 
that they've created themselves an impossible-to-boot partition layout, and 
guide them to go back to fix it.
 - grub-installer should support installing to multiple PReP partitions in 
parallel for proper full redundancy in the face of a disk failure.  This can be 
achieved in one of two ways:
  - the user can create a RAID1 of two partitions on different disks (e.g. 
/dev/sda1+/dev/sdb1 -> /dev/md0), and grub-installer can support installing to 
this as a PReP partition; or
  - grub-installer can detect multiple PReP partitions (possibly requiring the 
user to manually specify each one that they want to use) and install the 
necessary boot record to each of them in turn.

The 2nd and 3rd issues should be relatively straightforward to fix.  The
first issue is going to require some redesign of partman-md and is not
something we'll want to take on for 15.10.

Manually.
Attaching installation steps performed (single RAID device on top of single 
partition-pair of the 2 scsi disks).

[Mathieu Trudel-Lapierre]

Are you building the recipe for installation manually or is this install
done with the use of a pre-made recipe?

I'm afraid automatic recipes won't properly identify the PReP partition
when it comes up on a RAID (md) device; while it may work properly in
the installer, it would likely not be detected correctly by the system
when booting.

Got it; the other distro doesn't put the PReP partition on the RAID/md
device itself -- it uses the (non-RAID) partition on /one/ of the
underlying block devices.

[Bug 1487365] Re: Ubuntu14.04 .3 RAID installation fails on firestone

[Mathieu Trudel-Lapierre]

Any idea which distro you saw supported this? Upstream grub explicitly
does not support diskfilter writes (in other words, writing directly to
/dev/md* devices, LVM, etc), but rather expects one to write to the
underlying device, because there are just too many different cases in
which writing directly to the top layer might break things.

My workaround (I'm still testing) would be to have grub-installer pick
the underlying devices to install to.

Mauricio, thanks for doing the debugging, this is very helpful and
saving me a lot of time :)

This is exactly the problem I expected, and I believe we should be able
to workaround it in grub-installer.

Marking the bug as Triaged; I'll reproduce this setup and experiment a
bit with changes to grub-installer to come up with a way to fix this.
