** Description changed: + === Begin SRU Information === + [Description] + When curtin installs to a system that has multipath devices, it does not recognize this and enable them. + The result is that a system that has multipath devices installed will have Ubuntu installed to one of the non-multipath paths. The end user is then confused because they see root installed on /dev/sda1 and another device /dev/sdg1 (or other name) that has the same content as /dev/sda1. In addition to this confusion, if the user decides to use /dev/sdg1 and format it, they'll have shot themselves in the foot by destroying their root partition. + + The general solution is to install multipath-tools-boot when the system is detected to have multipath devices. To do this, curtin does: + curtin currently does: + a.) installs multipath-boot *only* when multipath devices are found, avoiding bug 1463046. + b.) writes /etc/multipath.conf to use user_friendly_names, avoiding bug 1432062. + c.) writes /etc/multipath/bindings file to provide a consistent named /dev/mapper/mpath name (solving bug 1429327) + + [Impact] + Without this fix, most power 8 systems will install to /dev/sda1 and let the user modify /dev/sdg1 (or whatever device name that multipath device appears as). This is not very user friendly, and quite confusing. + + [Test Case] + Positive case: + a.) install system that has multipath + b.) verify that multipath-tools-boot is installed. + c.) verify that system is booted with root=/dev/mapper/mpath0-part2 + + Negative case: + a.) install system with 2 disks without multipath + b.) verify that no multipath-tools-boot is installed. + + [Regression Potential] + The regression potential falls into 2 places: + a.) a system with multipath that installed without multipath fails to install or work after this + this is really a bug in multipath in kenrel or the package if we get here. We've done fairly significant testing to show that we're reliably installing. + + b.) a system without multipath is identified as multipath + The detection of multipath basically consists of looking for 2 devices that have a filesystem with the same UUID on them after creating a filesystem with that UUID. This is essentially not more than a check for a random sequence of bytes on all disks rather than a fully determinable identification of multipath. So, the failure case is: + 1.) we install to system and 'mkfs' the root partition + 2.) we find 2 disks that have the same UUID as the root device (the root device and one other) + In all likelyhood, that would mean that a filesytem with this UUID already existed on the system.

Some status here. I believe this is fixed in curtin trunk. Curtin should properly identify systems with multipath devices and install multipath-tools-boot and configure the system to boot from a reliable path. curtin at > revision 220 should be good. That is available in: wily archive: https://launchpad.net/ubuntu/+source/curtin maas experimental ppa for trusty utopic vivid: https://launchpad.net/~maas-maintainers/+archive/ubuntu/experimental maas testing ppa for trusty utopic vivid: https://launchpad.net/~maas-maintainers/+archive/ubuntu/testing/+packages The things left to get this functional in all supported places are: a.) copy to maas stable ppa b.)

this is a set of logs collected by https://gist.github.com/smoser/e0cd7fafef8f52c24571 I'm posting them here to show that this seems pretty functional and reliable at the moment. It installed trusty-hwe-u, trusty-hwe-v, vivid, wily in a loop 15 times each. It did fail on runs 16-20, but I believe the ipmi serial died, and since check for success was based on that, it marked them as failed and I did not get logs. ** Changed in: curtin (Ubuntu Trusty) Status: New => Confirmed ** Changed in: curtin (Ubuntu Vivid) Status: New => Confirmed ** Changed in: curtin (Ubuntu Trusty) Importance: Undecided => High ** Changed in: curtin (Ubuntu Vivid) Importance: Undecided => High ** Attachment added: "console logs from a deploy loop" https://bugs.launchpad.net/curtin/+bug/1371634/+attachment/4418544/+files/deploy-loop-logs.tar.xz ** No longer affects: linux (Ubuntu Vivid) ** No longer affects: multipath-tools (Ubuntu) ** Description changed: $ sudo blkid /dev/sr0: LABEL="Ubuntu-Server 14.04 LTS ppc64el" TYPE="iso9660" /dev/sda2: UUID="795a6e14-ea4e-4718-9e98-c6df3696920c" TYPE="ext4" /dev/sda3: UUID="0a91d81f-6a16-4b96-a92c-11ca8bdc4bf4" TYPE="swap" /dev/sdb2: UUID="1d14c1f3-716f-4fb8-9070-d321b39ffcb3" TYPE="ext4" /dev/sdb3: UUID="9c228177-d65c-4d19-a462-db1891e9781e" TYPE="swap" /dev/sdg2: UUID="795a6e14-ea4e-4718-9e98-c6df3696920c" TYPE="ext4" /dev/sdg3: UUID="0a91d81f-6a16-4b96-a92c-11ca8bdc4bf4" TYPE="swap" /dev/sdh2: UUID="1d14c1f3-716f-4fb8-9070-d321b39ffcb3" TYPE="ext4" /dev/sdh3: UUID="9c228177-d65c-4d19-a462-db1891e9781e" TYPE="swap" I'm not sure what exactly those block devices are (as in if they're raided in hardware or they actually represent physical spinning disks).

[Bug 1371634] Re: block devices appear twice
OK, so for trivial workaround fix, you can do:
a.) install with curtin as you have
b.) sudo apt-get install multipath-tools-boot
c.) printf "defaults {\n\tuser_friendly_names yes\n}\n" | sudo tee
/etc/multipath.conf
d.) sudo update-initramfs -u -k all
e.) sudo reboot
You'll come back up with multipath as the root device.
Oleg is working on a merge proposal for curtin that will do that by
default.
When the fix for bug 1432062 lands, then we wont even specifically need
the user_friendly_names patch.

[Bug 1371634] Re: block devices appear twice
Sorry for the vague comment earlier. What I meant was that, from a certification point of view, I can't certify a system that ships by default with dual RAID cards in a multipath configuration when Multipathing in Ubuntu doesn't work. That leads to a scenario where, out of the box on a fresh install you can destroy your own root filesystem by formatting a drive that you don't realize is actually your root fs...

[Bug 1371634] Re: block devices appear twice
Ok, so Oleg and I were looking at a solution, and figured we'd give the "maybe
it just works" path a try.
I installed a system, it installed onto /dev/sda (as this bug shows).
I then 'apt-get install multipath-tools-boot'
I rebooted, with the 'root=LABEL=cloudimg-rootfs' on the cmdline (as
normal). It died in initramfs unable to find root. The full bootlog at
http://paste.ubuntu.com/11547135/ .
The multipath-tools-boot package puts some code into the initramfs
(/usr/share/initramfs-tools/scripts/local-top/multipath) that does this:
| if [ -x /sbin/kpartx -a -x /sbin/dmsetup ]; then
| /sbin/dmsetup ls --target multipath --exec "/sbin/kpartx -a -p -part"
>/dev/null
| fi
That looks all well and good.
In the initramfs I did some debugging:
(initramfs) /sbin/dmsetup ls --target multipath
1IBM IPR-0 5EC2A9A0 (252, 1)
1IBM IPR-0 5EC2A920 (252, 2)
1IBM IPR-0 5EC2A980 (252, 5)
1IBM IPR-0 5EC2A960 (252, 3)
1IBM IPR-0 5EC2A9C0 (252, 4)
1IBM IPR-0 5EC2A940 (252, 0)
And then further debug, I find that dmsetup is calling kpartx seemingly
correctly, but kpartx is I think messing up.
I was able to fix this by booting with:
root=UUID=f7c3b31d-3411-420e-a57d-9318e43248ba ro console=hvc0
break=post-multipath
Then doing:
(initramfs) cat /tmp/myprog
#!/bin/sh
tgt="$1"
fixed=$(echo "$tgt" | sed 's, ,\\x20,g')
{
echo "input: '$tgt'"
echo "fixed: '$fixed'"
echo /sbin/kpartx -a -v -p -part "$fixed"
/sbin/kpartx -a -v -p -part "$fixed"
ret=$?
echo $ret
} >> /tmp/log 2>&1
exit $ret

Then ... after that, I have the devices I needed:
(initramfs) blkid
/dev/sda2: LABEL="cloudimg-rootfs" UUID="f7c3b31d-3411-420e-a57d-9318e43248ba"
TYPE="ext4"
/dev/sdg2: LABEL="cloudimg-rootfs" UUID="f7c3b31d-3411-420e-a57d-9318e43248ba"
TYPE="ext4"
/dev/mapper/1IBM\x20\x20\x20\x20\x20IPR-0\x20\x20\x205EC2A980-part2:
LABEL="cloudimg-rootfs" UUID="f7c3b31d-3411-420e-a57d-9318e43248ba" TYPE="ext4"
I exited from there, the remaining boot took over, and mounted the device
mapper device as /.
All happy.
So, if there weren't a bug in kpartx we'd have a very easy solution in just
installing the multipath-tools-boot package.
That said, it looks like user_friendly_names in /etc/multipath.conf might be
relevant.

[Bug 1371634] Re: block devices appear twice
Quickly reading over the report I would think this is a result of the installer bug I reported as bug #1447167. The problem is that if you configure a system for multipath, it will present each path as an independent drive. And that causes a lot of confusion when a system has data on those and comes up without the multipath tools installed. To the OS this looks like multiple disks having the same filesystem UUIDs which conflict when creating disk-by/... links in /dev. Even worse LVM finds two PVs with the same ID and bails (iirc). I theory (with a lot knowledge and care) it is possible to install single-path and convert the whole system to multipath later. But frankly I think when the installer was told to enable multipath detect, it should automatically install the tools. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1371634 Title: block devices appear twice To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/curtin/+bug/1371634/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This is a multipath issue. The box has two cards with redundant paths to each disk.

[Bug 1371634] Re: block devices appear twice
Joseph, I honestly don't know how the systems are set up. I suspect you're right, that there are 2 physical disks raided together. I don't think that changes the bug at all though. The kernel should only show me one of those devices, right? If I configured hardware raid to show 2 disks as 1 in raid 1 I certainly wouldn't expect to have to know that from user-space (I'm kind of surprised the *kernel* ever see the individual disks there). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1371634 Title: block devices appear twice To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1371634/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
