# How to fix: failed to create runc console socket: mkdir /tmp/pty160439680 When running command: ```bash opencli user-login stefan ``` If you receive an error: > failed to create runc console socket: mkdir /tmp/pty1604396800: no space left on device: unknown It indicates that the disk space is at 100% and you need to first free some space on the server in order to login. First, find the partition that is full: ```bash df -h ``` Example output: ```bash df -h Filesystem Size Used Avail Use% Mounted on tmpfs 3.2G 307M 2.9G 10% /run /dev/vda1 296G 296G 0 100% / tmpfs 16G 252K 16G 1% /dev/shm tmpfs 5.0M 0 5.0M 0% /run/lock /dev/dm-1 10G 5.7G 4.4G 57% /var/lib/docker/devicemapper/mnt/ef7bedfb84a4b7d216944174518a29d79edbc11a17546f0a6f9f691128a0577d /dev/dm-3 10G 1.1G 8.9G 11% /var/lib/docker/devicemapper/mnt/ff5c36635ee829daf9f9aef6b23b02afb7ee34431a2c37c4321b97a1568ba435 /dev/dm-5 160G 6.5G 154G 5% /var/lib/docker/devicemapper/mnt/77de40032c66f2f6926209de4e58a0eced5113cdc32bb363127857b1442a2989 ``` In this example we see that the entire / is full, so we can use a tools such as `ncdu` do check what is using the disk space: ```bash ncdu / ``` Navigate through directories and delete any old backups or log files by pressing `D` on the keyboard. After freeing disk space, repeat the command.
