Hi all.

 

Upgraded from 12 to 14b without difficulty last week, creating new docker image at /mnt/cache/docker/docker.img without difficulty. Then noticed today that mover moved it to disk1. So I wanted to move it back. I stopped docker, deleted the image on disk1, and then tried to create new image on the cache drive again (this time with a plan to mark the docker share cache only). Unfortunately, I can't make the new image. Here's the error:

 

php: Not starting Docker: new image file path doesn't exist

 

Full syslog attached from most recent restart. (I have cleared browser cache, soft rebooted, and hard rebooted all with same result.)

 

The array seems to be functioning fine; just can't use docker.

 

Thanks,

 

TD

 

Update: Scrubbed cache disk file system and  found zero errors. Attempted to create new share called "Docker" and mark it cache only, and got the following error:

 

Mar 6 07:06:44 TARDIS emhttp: shcmd (51): mkdir "/mnt/user/Docker"

Mar 6 07:06:44 TARDIS shfs/user: cache disk full

Mar 6 07:06:44 TARDIS shfs/user: shfs_mkdir: assign_disk: Docker (28) No space left on device

 

Needless to say, the cache disk has plenty of space (998 GB free out of 2 TB) and I am able to copy files directly to the disk from my windows workstation via smb.

I'm thinking you might have forgotten to set a size for the docker image. Try changing the size if you did have it set before.

Not sure if that did it, or the reformat of the cache disk, but now I can create a new docker image. Odd that it wouldn't have taken the size already specified in the field, though.

 

Thanks.

A lot of people have been bitten by the fact that an example size is displayed, but is not actually set until you enter one.  I would think it would be better if the code handled the case of the size not set as meaning use the displayed example size.

Absolutely this needs to be hit with the bug hammer. That is not intuitive at all.
