How to free up space in NCS5002, received A monitored device / is above 80% utilization during upgrade

[Ahmed Muhi]

Hello All,

I was trying to upgrade the NCS 5002 from IOS-XR 6.0.1 to IOS-XR 6.1.2, during the upgrade I received the below log message, still the upgrade was successful,

RP/0/RP0/CPU0:Dec 19 11:47:57.098 : resmon[358]: %HA-HA_WD-4-DISK_WARN : A monitored device / is above 80% utilization. Current utilization = 86. Please remove unwanted user files and configuration rollback points.

I would like to know what does the device / stands for, does it stand for rootfs, and if I can free up some space or increase the size of this directory, also please find the show media, and admin show media before and after the upgrade.

After the upgrade
