ok, I can give it a try, but deleting something with data in it makes me a little nervous 
Iâm having the same issue as well, I tried uninstalling plex but it just says its starting, I tried turning off rockons and rebooting, but when i turn rockons back on it still says plex is starting. Any other ideas?
try using chrome browser, it has issues with firefox and other browsers. I had an issue where the dashboard would not work in firefox after the upgrade. I tryed it with chrome and it worked fine.
I cleared the cache in fire fox and everything went back to normalâŠ
Did it work for you?
Nope. Iâm using Chrome. I even cleared out all the cache from chrome. Plex and Transmission still say they are starting.
same here rockons stopping and starting since days and also a reboot has not changed anything on the state of it.
Sorry guys, I am working on this. Any chance you could e-mail logs to support@rockstor.com @herbert?
One thing I am noticing consistently is that rock-on/docker service itself sometime takes a long time to start and while itâs in pending state, if you start again, it further confuses it. For now, if you get an unknown internal error when starting the rock-on server, just wait and monitor the system->services page and the service should turn on eventually. You can also check with systemctl status docker.
Rock-on improvements are coming, appreciate your patience.
any other idea how to fix this ?
I am stuck and the services are also not running ?
tried to stop docker from command line and got this error, but df -h shows enough space. much more confused now
[root@Homeserver ~]# systemctl stop docker
Error: No space left on device

btrfs fi show p1_r1btrfs fi df /mnt2/p1_r1btrfs fi usage /mnt2/p1_r1
I deleted all snapshots created on the root pool /mnt2/rockstor_rockstor and now everything works fine. Which means no error on starting and stopping the docker service.
Still all my docker containers are stuck in now 3 states stopping, starting and uninstalling
Also funny information, I had my latest snapshot auto-created on the /mnt2/rockstor_rockstor pool on sept 2015. Still no knew one appeared and as far as I understood they should be created quite often automatically.

need help because those rockons are now offline since weeks and I need them. otherwise I have to move on to something else 
I also tried to uninstall the plex rockon and install it again, outcome is another error

To be honest, I am little unsatisfied with what I rockstor provides. the rockons are far away from stable and up to date and this the main reason I started to pay for rockstor but still it feels like a second citizen.
hey @herbert, I applaud you for trying a few variations and reporting back very useful information.
The fact that you are not seeing the eternal spinning gear is indeed a good sign 
The âcould not find imageâ error indicates that something went wrong in the Rock-On root share. May be some snapshots got deleted? Since all the application data of your Rock-Ons is mapped via Shares, there is no harm in just starting over with a new root share. All your app data should still be there(you may want to start fresh with config shares, however⊠this is app specific and not really in our control).
These are the steps Iâd follow (also read this doc for general tips about the root share, best practices etcâŠ)
- Uninstall all Rock-Ons.
- Turn off the Rock-On service
- Create a new Share to use as Rock-On root share.
- Configure the service to use the new root share
- Delete the old root share(youâll need to delete all the snapshots inside it first)
- Start the service
- Click Update so all app profiles are updated.
- Install your Rock-Ons. Use the same Share mappings to retain app data.
Regarding your last comment, your frustration is understandable. There is volatility with the Rock-Ons framework which we addressed quite a bit in .11 cycle. One of the key changes that I think is directly related to your problem is how we ship docker binary. It is after all third party software and rapidly evolving. Previously we used to deploy/redeploy from the upstream. Now, we are regulating that just like we do the elrepo kernel. Any updates to docker go through the testing channel first. The other thing to note is that each Rock-On is backed by third party docker images. The core team tests as much of these as possible, but it is a lot of work, itâs not the core of Rockstor and we shouldnât be assumed as the maintainers of individual Docker images. Our goal is to provide a robust and generic way to host and manage these apps via the Rock-On framework. Anyway, thanks for your patience and report back how it goes!
Hi
thanks for helping this fixed it, btsync is up and running
plex is on its way to start as well
one issue I do have, I cannot delete the old rock-ons share, deleted all snahpshots, webui says its not empty. deleted the folders in the directory via CLI and get stuck here:
rm: cannot remove âbtrfs/subvolumes/428b411c28f0c33e561a95400a729552db578aee0553f87053b96fc0008cca6aâ: Operation not permitted

nevertheless, I am still waiting an easier way to integrate standard docker images into the rockstor architecture which makes it easier to move away from the âoutdatedâ rock-ons.
which brings me to the next part, I know rock-ons is not your core thing, but it is there an this means they should also be handled properly, especially because you now have paying customers.
for the btsync rock-on, it is so outdated that I cannot use any new features or make some settings which are important for my setup.
I know I could update the docker on my own on my system, but this is not what I expect from the system. I still love the idea of centos with btrfs and a great webui, so I gonna stick at rockstor at least for another while to see whats happening. nevertheless, I already went to the unraid homepage to see what they did and thought about moving back
but not yet - I am too curios to see what you are going to accomplish.
Right. I do know this issue. You can delete these Snapshots with btrfs subvol delte /mnt2/[your_pool]/[rock-on_root_share]/btrfs/subvolumes/* â you get the idea. After that, you should be able to delete the Share. Iâve also created an issue to improve support for scenarios like these. So stay tuned.
I am really not interested in just putting a GUI over Docker. But we are doing something more higher level and solution-y. Take a look at rockon-registry repo. Your feedback has been very useful so far and I encourage you to continue to engage and help us improve swiftly.
Iâve tried to engage the Bittorrent Team on this and they showed some interest but I donât see them actively maintaining the image and what they currently produced for Rockstor is limited and closed. Perhaps you can voice your concerns on their forum and if thereâs enough support, it may just push them enough.
Haha, thanks! Could you let us know a list of things you think Rockstor should do better vs unraid? perhaps, in a separate forum topic?
getting rid of the subvol helped and I could delete the share. thanks
I like the idea of having something more high level than just a docker gui, but this also means somebody has to create the necessary files and make the needed adoptions and updates to your approach. which more or less every other NAS system tries to solve as well. the outcome is having outdated docker images running, nobody can easily change or update.
having a system in place which allows to run standard docker images âas wellâ would make it much easier for users to get the needed features on rockstor. there are already a lot management tools out there, why not integrate one of them as the community âunstableâ approach and Rock-ons could still exist as validated and stable solutions for rockstor.
Most people I know choose their NAS in the home environment based on the available plugins.
about unraid vs rockstor 
well I start a discussion about it

I talked to the btsync team and they said there is already an official docker image. is it now possible to use it on our rockstor systems?

cheers
So do I. But as a bit of a stopgap in the mean time, you could consider installing dockerui:
docker run -d -p 9000:9000 --privileged
âname=dockerui -v /var/run/docker.sock:/var/run/docker.sock
dockerui/dockerui
Will expose on port 9000 a nice UI to examine the state of your Docker containers and perform administrative tasks. Not secured, though, so only for trusted environments behind a firewall.

this was just too easy, entering the command and everything else happend magically
thanks
but still how to configure the docker image (btsync) so it takes over the old btsync image coming from the rockons?
have you any advice, this is all new for me
Just want to update that the issue for this is now resolved as of 3.8.11-15 and should be part of 3.8.12 coming soon.
