Hi guys! I got failed during upgrading process from the admin. And then I tried to rebuild again, but I face constant problem: > Layer already being pulled by another client. Waiting. ![](https://global.discourse-cdn.com/meta/original/3X/0/5/0534c4beb0e9d929334ce47146f365c57e3c2047.png) Someone please help me ☹ ---

Not sure, try rebooting. Or waiting a while. ---

Good idea try `docker --version` and `docker --info` as well. ---

@sam, @codinghorror The system automatically generate the app.ml.save, and the app.yml becomes empty totally. ![](https://global.discourse-cdn.com/meta/original/3X/5/0/505877a1f8c365576209a855ff029f0eef76c5a4.png) I deleted the app.yml, then transfer an original app.yml. And then it becomes empty with the size of 0. I try nano containers/app.yml to modify it. After adding the content, it can not be saved by the error of “No space left on device” ![](https://global.discourse-cdn.com/meta/original/3X/3/b/3b007324fcea51ad21aaffbec1813294e1a4fc1e.png) Please help me guys @@ ---

The error in nano says “No space left on device”. Have you checked that you haven’t run out of disk space? ---

Well, that’s all I’ve got. I would recommend that you run `docker -- version` and `docker --info` for @codinghorror though, the results can be very helpful for them to see what is going on. ---

@codinghorror, @sam, @jomaxro I just want to let you guys know that the problems were solved by resizing my server for larger ram and disk. Thank you so much for kind helps 🙂 ---
