The root (/) filesystem is filling up, or is 100% full.
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/maintenance.pl line 129.
Under 184.108.40.206 & 220.127.116.11, 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.
