The root filesystem on an 5200/5220/5230 appliance is 100% full

  • Modified Date:
  • Article ID:000021854


The root (/) filesystem is filling up, or is 100% full.

Error Message

The /tmp filesystem cleanup script only removes specific files, resulting in a full root filesystem after several days due to Callhome telemetry files filling the root filesystem

If attempting to access a maintenance shell via the CLISH (Support > Maintenance > elevate) commands, you may encounter the following error:
<!-- Maintenance Mode --!> Use of chdir('') or chdir(undef) as chdir() is deprecated at /opt/NBUAppliance/scripts/ line 129.


Under &, Callhome telemetry archive files (/tmp/nbtelemetry*) can be quite large, and are not removed automatically.

Under certain conditions, this can result in a full root filesystem within 4 days of enabling the Callhome feature.

For example:
my-nbu5220:/tmp # ls -lat | grep nbtelemetry
drwx------ 3 root root 4096 Jan 9 05:43 nbtelemetry_201401090543Ffs
drwx------ 3 root root 4096 Jan 9 05:28 nbtelemetry_201401090528LcG
drwx------ 3 root root 4096 Jan 9 05:13 nbtelemetry_201401090513ZMV
