+# 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.
