Storage issue when trying to load docker image on centos7-CodePudding

Initially I've increased the volume size of "/dev/mapper/rhel-var" from 2g to 9g.

When trying to load docker image I get this error:

Filesistem:

$ df -h

Is it any other volume that needs aditional storage space?

Docker image (I mean the .tar file) space is around 4.8G

$ ll

Thanks Cosmin

Later edit: Got this crash of the machine

CodePudding user response：

The problem was:

/dev/mapper/rhel-var_log_audit  3.0G  2.9G  105M  97% /var/log/audit

I've check according to "Start loading it, while it is happening, open a second terminal, run df repeatedly and observe which usage chagnes over time. – KamilCuk Oct 28 at 17:14"

and this volume went full then crash.

Conclusion: When loading a docker image here is where it writes things, at least in:

/var/lib/docker
/var/run/docker
/var/log/audit

I've cleared the /var/log/audit and it worked.

Thanks!
