After update to 3.9.2-3 Yum updates - Plex - Shares are not working

[upapi_rockstor (Ulrich)]

Hi,I’m a newbie to rockstor and Unix systems. Perhaps you can help me solving several problems.
I’m running rockstor wit Plex since a couple of month with no problems until the last Update to 3.9.2-3.

What I have done:

• I started the Update of packages on the Web UI

• This did not work. I received this error
  Error: Package: rockstor-3.9.2-0.x86_64 (@Rockstor-Stable)
  Requires: docker-engine
  Removing: docker-engine-1.13.1-1.el7.centos.x86_64 (@anaconda/3)
  docker-engine = 1.13.1-1.el7.centos
  Obsoleted By: docker-ce-17.09.0.ce-1.el7.centos.x86_64 (Rockstor-Stable)
  Not found
  Available: docker-engine-1.9.1-1.el7.centos.x86_64 (rockstor)
  docker-engine = 1.9.1-1.el7.centos

• I made a yum update in a terminal. It completed without any error. I rebooted the system.
  Then the trouble starts:

• Bootstrap service cannot be set to ON

Some of the shares are not mounted anymore

Perhaps this is the reason why I cannot access the Plex UI anymore?

Even a recovery of a disk image (made with “dd”) didn’t resolve the problem.

If you need more information don’t hesitate to ask for.

Would be great if someone can help me.

cheers
Uli

PS.: sorry for my bad english.

[EDIT]: next steps to a solution
I managed to mount the Shares again, start the bootstrap.service and enable Plex WebUI by enabling the btrfs quota.
“btrfs quota enable /”

But on the rockstor webUI it shows 0 size and usage:

How can I solve this?

[EDIT]: try to resize a share results in

@upapi_rockstor Thanks for the excellent report and for helping to support Rockstor.

@upapi_rockstor

I made a yum update in a terminal. It completed without any error.

Not sure what happened with the Web UI update but it looks like you tried it just as one repo was updated and the other was not. Might just have been bad timing.

@upapi_rockstor

Bootstrap service cannot be set to ON

Well noticed, that really helped with looking into this.

I have replied to another thread that you have contributed to re the failure to mount shares. That reply:

Rockstor 3.9.2-3 shares unmounted after reboot

@Horatio Hello again. @Hooverdan and @upapi_rockstor A belated welcome to the Rockstor community to you both. I haven’t gotten to the bottom of this hole issue just yet but I have managed to reproduce the failure to mount due to the exception being raised, along with the obvious repercussions, during the attempt to establish share usage when quotas are disabled. This would seem obviously ‘over the top’ and non robust so I have started by submitting the following pr which is ready for review: …

details the now pending pr which contains a fix for at least the failure to mount. The other consequences of our failure to enable quotas (can’t resize shares and 0 share usage stats etc) is currently in the works.

Hope that helps and thanks again for pushing through this one and sharing your findings.

Happy New Year,

after Yum update rockstor and reboot everything works perfect.
Thank you very much.

@upapi_rockstor Thanks for the update and glad your sorted again.

Happy New Year,

Same to you and all.

We had a little bit of a bumpy patch back there for a bit but hopefully we are on the other side.

And thanks for helping to support Rockstor development.
