Description

ceph version 13.2.0 (79a10589f1f80dfe21e8f9794365ed98143071c4) mimic (stable)
Python 3.5.5
OS: Gentoo

fenrir ~ # ceph-volume lvm create --bluestore --data /dev/sda
Running command: /usr/bin/ceph-authtool --gen-print-key
Running command: /usr/bin/ceph --cluster ceph --name client.bootstrap-osd --keyring /var/lib/ceph/bootstrap-osd/ceph.keyring -i - osd new a1ff1660-7007-4d52-9ec9-bbb7bfc63fd8
-->  TypeError: memoryview: a bytes-like object is required, not 'str'

The log gives no indication of WHY ceph-volume was unable to prepare the device.

Note, this was a disk that was the bluestore storage of an OSD created by ceph-disk, so this isn't a hardware issue, or an issue of a non-working cluster. I'm just trying to migrate my OSD to ceph-volume.

TypeError: memoryview: a bytes-like object is required, not 'str'

Isn't a meaningful error message. Heck, combine "ceph-volume" with the python error message on Google and you get 2 results total, and neither of them has anything to do with either ceph or python.

lvm prepare was unable to complete
will rollback OSD ID creation

Doesn't give me any direction in how to trouble shoot... since I can (and did) create the logical volume by hand, I'm at a complete loss on what to investigate.

And, it's also a liar. It totally did not roll back the OSD id creation. Had to purge that by hand (ceph osd purge # --yes-i-really-mean-it).

This looks like Python 3 compatibility problem. Can you confirm that is the case in your system?

If it is Python 3 as I suspect, would it be possible for you to try this patch?

I verified this is happening on Python 3 instances. subprocess wants to receive stdin in bytes not 'str' so we must set the encoding, except Python 2 doesn't take that
argument.

After applying the suggested patch and rebuilding:

--> TypeError: init() got an unexpected keyword argument 'encoding'

#6 Updated by Alfredo Deza 8 months ago

Yeah that would happen on a Python 2 environment. I am working on a patch to make it work for both. You didn't confirm if the error happened in a Python 3 server

#7 Updated by Alfredo Deza 8 months ago

  • Subject changed from ceph-volume fails to create OSD on raw sata hdd to ceph-volume fails to create OSD with Python 3
  • Status changed from Verified to In Progress

#8 Updated by Michael Jones 8 months ago

I use python 3.5.5, as indicated on line 2 of my original response.

The shebang at the top of the file is for python 3.5, and running the ceph-volume script directly with python 3.5 all spit out the error I indicated.

#12 Updated by Alfredo Deza 8 months ago

That sounds like a new (different) issue. Can you get us the log output when you ran that command or run it with the debug env var:

CEPH_VOLUME_DEBUG=1 ceph-volume lvm zap /dev/sda

Since you are seeing this for 'zap' and no longer for 'create', I am going to move ahead with the fix for this bug and close it once the PR merges.

#13 Updated by Alfredo Deza 8 months ago

Would you mind sharing what distro are you using? Perhaps it would be far easier on our end to try and get functional testing on that distro vs. attempting to find these on a case-by-case basis

#18 Updated by Alfredo Deza 8 months ago

After the last patch you've applied I see:

[2018-07-19 03:36:51,666][ceph_volume.devices.lvm.prepare][ERROR ] lvm prepare was unable to complete

Since you are using 13.2.0 it is missing this patch https://github.com/ceph/ceph/pull/22640

Would be super useful if you could apply that and hopefully get some log info on why that is failing (the last TypeError is still a bug though)

#19 Updated by Michael Jones 8 months ago

Applied patch by hand.

#20 Updated by Michael Jones 8 months ago

It's getting a little farther though.

Managing to create lvm stuff, where as it wasn't before, and managing to purge the OSD that it failed to create.

Still needs to clean up it's LVM stuff if it fails though. I doubt many admins want to go around hunting for volume groups for failed OSDs.

#21 Updated by Alfredo Deza 8 months ago

Was able to narrow down this one, and I have a test and a fix.

The fix is here: https://github.com/ceph/ceph/pull/23141/commits/2133087e9016684c55a8770dd2d8bef5557bd2fd

I believe that should get us to a working OSD. Let me know

#22 Updated by Michael Jones 8 months ago

Patch allows ceph-volume lvm create /dev/sda to work, apparently successfully.

The command returns success, and the log messages indicate that it thinks everything worked properly.

The OSD process that gets spawned after ceph-volume finishes core-dumps immediately, and now my harddrive is unresponsive to any program except direct writes like dd, even after a reboot (which apparently requires me to press the power button. Software reboot hangs for apparently forever).

Reproduced the new problem on two different drives.

I'm very frustrated that the ceph project deprecated ceph-disk, which was working without issues for me, in favor of a new tool that

1) Requires new kernel modules, and new userland utilities, with a whole new set of headaches for management.
2) Is obviously not fully baked yet.

Redmine refused to upload all my log files, apparently.

#24 Updated by Alfredo Deza 8 months ago

Since these patches are now working for the problem you reported I will close this once the functional tests are passing on the PR.

If you would still prefer ceph-disk, you can do so up until Mimic. It is no longer present for the next (nautilus) version of Ceph.

#25 Updated by Michael Jones 8 months ago

You can close this issue.

Please open a new one for the segmentation fault (or tell me that I need to, so I know to do it.)

If you would still prefer ceph-disk, you can do so up until Mimic. It is no longer present for the next (nautilus) version of Ceph.

That's... the problem.

Don't mark something as deprecated until the replacement actually works.

#26 Updated by Alfredo Deza 8 months ago

Sorry that you feel that way about using the new tooling. We do test ceph-volume and it does work in our environments without problems, we acknowledge that Python 3 compatibility is an
ongoing process and we are trying to get more functional testing around that to prevent issues like the ones you found.

ceph-disk has a long tail of problems that were recently documented here: http://docs.ceph.com/docs/master/ceph-volume/intro/#ceph-disk-replaced

ceph-volume does have some issues but it works well and does not display any of the impossible-to-fix issues that ceph-disk had. I am happy to accept more issues as you find them, they are super
useful! I appreciate your patience while we get these fixes sorted out.

For core dumps I would suggest opening a ticket against the rados project: http://tracker.ceph.com/projects/rados/issues/new

#27 Updated by Michael Jones 8 months ago

Don't deprecate a feature until the replacement has been deployed and in use by the community for a full release.

You simultaneously deprecated a working feature (even if there are problems with it), and introduced the new tool at the same time.

You should have announced that ceph-disk was deprecated on the nautilus release, a full release after ceph-volume became available. Or announced it's deprecation for the mimic release (as you did), with it's removal the release after the nautilus release, which is not what you're doing.

Unless both tools live side by side for a full release (without one of them being deprecated), you're just begging for something to go wrong.

But whatever, this isn't the place to discuss this kind of thing, and I doubt you personally care about my opinion on the matter.

Thank you for working with me to repair the ceph-volume issues.

ceph-volume does have some issues but it works well and does not display any of the impossible-to-fix issues that ceph-disk had.

I mean, I disagree that it works well... but I have a different perspective on the matter than you do.

I'd be very interested in a blog post describing all of these issues that ceph-disk has, and what steps the Ceph developers took to get udev to fix it's problems. Udev is at the heart of the majority of linux machines out there, and I don't disagree with you that it's... not fun, so I'm curious what led the Ceph project to abandon it in favor of LVM (which is not as widely available as udev) and whether the udev developers were simply unwilling, or unable, to address any of the problems.

Created a new issue for rados.

Don't deprecate a feature until the replacement has been deployed and in use by the community for a full release.

ceph-disk was initially deprecated in Luminous, we backtracked and it is now deprecated in Mimic. Luminous users will not see a deprecation warning. The deprecation
banner is in Mimic only.

You simultaneously deprecated a working feature (even if there are problems with it), and introduced the new tool at the same time.

This was discussed in the ceph-devel mailing list, a consensus was reached and the deprecation was set. For someone installing today, it will not see a deprecation warning
in Luminous.

You should have announced that ceph-disk was deprecated on the nautilus release, a full release after ceph-volume became available. Or announced it's deprecation for the mimic release (as you did), with it's removal the release after the nautilus release, which is not what you're doing.

These opinions would've been valuable for sure, when the discussion happened. The community agreed that waiting another full release was fine. We can't really revert this to accommodate your opinion.

Unless both tools live side by side for a full release (without one of them being deprecated), you're just begging for something to go wrong.

Both tools are living side by side for a full release (Luminous) without one of them being deprecated.

But whatever, this isn't the place to discuss this kind of thing, and I doubt you personally care about my opinion on the matter.

I would welcome your ideas and discuss them further in the ceph-devel mailing list (or the ceph-users mailing list) if you prefer.
