Script fails after virtual machine is restarted #27

Closed nithin-bose closed 8 years ago

nithin-bose commented 8 years ago

Script fails with the following error: Restart Docker Machine ... Too many retries waiting for SSH to be available. Last error: Maximum number of retries (60) exceeded

I am not able to connect to the machine even with docker-machine ssh

tonivdv commented 8 years ago

Can you try to restart it again? And print the logs /var/log/bootlocal.log and /var/log/boot2docker.log.

If you can't re-access the virtual machine (hopefully not an important one), can you try again with another machine?

Also are you using last versions of everything?

nithin-bose commented 8 years ago

The status of the machine is "running". SSH does not work. It was not an important machine... I recreated the machine and re-ran everything. But it fails at nfs verification.

Checked that the host nfs server is running. The following is on the bootlocal.log: mount: mounting 192.168.99.1:/Users on /Users failed: Bad file descriptor

I am running the docker-toolbox 1.9.0d. Boot2Docker version 1.9.0, build master : 16e4a2a - Tue Nov 3 19:49:22 UTC 2015. Docker version 1.9.0, build 76d6bc9

@nithin-bose Can you reboot your mac? Seems related to: https://github.com/adlogix/docker-machine-nfs/issues/22#issuecomment-160656738

nithin-bose commented 8 years ago

restarted.... but same as above Using mac 10.11.1, if that matters

nithin-bose commented 8 years ago

Further on this, I am able to ping 192.168.99.1 (host) from 192.168.99.100 (vm) immediately after creating woth docker-machine. However after running docker-machine-nfs, ping from the host fails. However, pinging something outside, like ggogle.com works.... could it be that the network settings are affected somehow??

tonivdv commented 8 years ago

Certain that no firewall is blocking this? Cause another user had that case too.

nithin-bose commented 8 years ago

No firewalls, unless boot2docker or virtual box has one. Mac firewall is off. I have no idea why ping should fail after the script is run.

nithin-bose commented 8 years ago

@brandontamm I will try this out and let you know

nithin-bose commented 8 years ago

Tried this.... same issue... after running docker-machine-nfs, even though I can docker ssh into the machine, ping from boot2docker to host machine fails.

I am not sure what is causing the issue. I really want this to work. Or at least something that passes fs events to the docker machine. :(

tonivdv commented 8 years ago

Hey @nithin-bose ,

When you ssh in your machine, can you ping your host ? (Not the 192.168.99.1)

nithin-bose commented 8 years ago

Did not get you. 192.168.99.1 is my host and 192.168.99.100 is my boot2docker vbox guest machine. The same is used for nfs as well. The commands above are from the boot2docker guest. Ping works fine if I docker-machine ssh and do it before running docker-machine-nfs.

tonivdv commented 8 years ago

On my machine I also have the 192.168.99.1 which is an ip from virtualbox (vboxnet4), but my actual ip from my host (mac os) is 10.0.0.X ... the ip received from my router. Can you ping that one from your guest?

Not sure this test is worth anything. I'm no expert in all underlying network stuff. Just trying to figure out why your nfs is not connecting between host<->guest.

Cheers

T

nithin-bose commented 8 years ago

I dont see any 10.* ip in my ifconfig. I only have a vboxnet0 adapter which shows the ip to be 192.168.99.100 :( event i dont understand why its not working.... your script is simple enough.... nfs-client seems to hang.... the same is the case with my friend too.... which versions are you on?

tonivdv commented 8 years ago

Hey @nithin-bose ,

My ip is 10.* because my router is in that range. But it could be very well another ip. Most routers give an ip in a range of 192.168.0.X . Anyway not sure this will tell anything.

For all the things a I use, all are at latest version.

nithin-bose commented 8 years ago

Oh sorry.... vbox used to give ip in the 10.* range so i thought you were refering to that. I will check this out and let you know. Thank you for your patience :+1:

Same here, with a fresh installation starting from the last docker toolbox, the nfs share doesn't work.

paolomainardi commented 8 years ago

Problem fixed, it was missing the 127.0.0.1 localhost entry on my /etc/hosts.

nithin-bose commented 8 years ago

@paolomainardi which hosts file was missing this entry the host or guest?

tonivdv commented 8 years ago

@nithin-bose It should be on the host. Guest doesn't have to be touched on that level.
