Kevin who Posted February 28, 2020 Share Posted February 28, 2020 Sorry to bother you guys. I got some problems with my system, after I update many docker containers on web gui at one time. I think The main problem is just what i said, so now I can't open web gui, and every command of docker is dead. Every command, including 'docker info'. It just not response at all. I can't use web ui now, but I can still use ssh to connect. I tried to reboot system many times, but it just didn't work. I even can't cd into /var/lib/docker. So what shoud I do now? Can someone help me with that? Truely thanks a lot! Quote Link to comment
trurl Posted February 28, 2020 Share Posted February 28, 2020 See the "Need Help?" sticky pinned near the top of the General Support subforum for instructions on how to get us more information. Diagnostics preferred if you can get it. Quote Link to comment

JorgeB Posted February 29, 2020 Share Posted February 29, 2020 There's a btrfs related kernel oops, it doesn't identify a specific filesystem but the docker image would be the most likely culprit, re-create it, rebooting after that's done is also a good idea. 1 Quote Link to comment
trurl Posted February 29, 2020 Share Posted February 29, 2020 If you can't get into the webUI try disabling docker by editing config/docker.cfg on the flash drive, and reboot in SAFE mode. 1 Quote Link to comment
Kevin who Posted February 29, 2020 Author Share Posted February 29, 2020 thanks, I'll try it Quote Link to comment
Kevin who Posted March 1, 2020 Author Share Posted March 1, 2020 well, I set the command DOCKER_ENABLED="no" and reboot then It seems to have no effect If the system need to reboot in safe mode, I don't know how to do when use remote connect Quote Link to comment
trurl Posted March 1, 2020 Share Posted March 1, 2020 Editing that file won't change anything until Unraid reads it again. If you don't have access rebooting is the way to do that. SAFE mode was just an extra suggestion but just reboot if you can. Quote Link to comment
Kevin who Posted March 2, 2020 Author Share Posted March 2, 2020 Thanks for reminding! I found that simple command 'reboot' won't work because of the stuck process. So when I use command echo 1 > /proc/sys/kernel/sysrq echo b > /proc/sysrq-trigger The system finally rebooted, and now I fix the problem. Thanks again! Quote Link to comment
