last night my system froze and i had to reboot.  after rebooting and running a parity check, i no longer have a dockers tab.  any thoughts on how to get that back?

 

diagnostics file attached.

Looks like its having trouble mounting disk11 and you don't have a cache disk. What disk is your docker.img on?

It lives on disk 12

Post a screenshot of Settings - Docker

id be happy to but every time i try to post a screenshot here it says its too big.  any tips on how to get that posted?

also - i just tried to stop the array and it seems to be hung on unmounting user shares.

What are you using to save the screenshot? I just saved a jpg of my entire screen and it is only 151KB.

i am using a chrome extension called awesome screenshot on osx.  stores it as a png that is 210kb

settings screen just says:

enable docker: yes

default image size 10 GB

docker image: /mnt/disk12/docker.img

delete image file checkbox is not checked.

Delete it and recreate it larger. Your docker.log shows

time="2016-05-20T13:48:38.277244774-04:00" level=fatal msg="Error starting daemon: Insertion failed because database is full: database or disk is full"

How many dockers do you normally have installed?

wont i lose all the settign in my dockers then?

 

I usually run plex, sonarr, deluge, nzbget and couchpotato

Your docker settings are stored on the flash. After you get the Docker tab back you can add back each of your dockers by selecting their templates from the Docker page. The dropdown selection will include selections such as "my-plex" or "my-whatever" and when you select them the settings from that template will be reloaded from the flash and when you add the docker it will be downloaded and run with those settings.

 

Deleting and recreating docker.img is an often used solution to filling up your docker space, and unRAID makes it easy to get them all back. Any appdata the dockers used will be on cache or wherever you told it to put them so only the code needs to be reinstalled. Your docker settings are on your flash, and your docker data are on your drives.

well that is just awesome - I deleted the docker image and recreated it at 20GB and grabbed installed all the containers again and all my settign came right back as if nothing had happened.

 

great stuff!  thank you.

 

one more question - given the containers that I previously listed, is it normal that the img file ran out of space?  how big should i reasonably make the img?

I have 9 installed with 20GB and have never come close to running out of space. However, if you don't have your volume mappings configured correctly it is possible that some of your dockers are writing some of their data inside docker.img instead of outside on your drives. There are several threads about this. Have you read the Docker FAQ?

I have 4 dockers installed and have yet to go over 1.8 Gig used of the image.

I run eggdrop, pytivo, nzbget, and transmission.

 

It all depends on which dockers you run and if you have them configured properly, on how much image space they use.

hmm - i wonder why running plex, sonarr, deluge, nzbget and couchpotato would create such a large file.  are there any common configuration issues for these dockers that might cause a large file?

Having them download to within the image is the biggie.  All downloads (even incomplete) should go to a completely separate share)

i had that thought to but I believe I have them all going to various user shares that are mapped in the docker settings.  How would I tell if something is downloading files into the image?  like what would a path inside the image file look like?

Any path that's not passed through when you add it.

 

Also look for capitalization.  You pass through /downloads but are saving the uncompleted to /Downloads

hmm - i just took a spin through the settings in all my dockers and it appears as though the download folders are all using the pass through paths set up in the docker settings.

 

not sure why the file is so large.

 

 

Just delete it then.  Add the apps back via CA's previous apps section and you'll be back up and running like nothing ever happened.  And then you have a clean slate to watch to see what happens with the size
