/localdisk is mounted in preallocated space within /opt, so at least /localdisk being full doesn't cause an impact. Delete the core files you see in dir disk:/corefiles and you will clear the disk warning. You will use the syntax del disk:/corefiles/<filename>.

You may also want to open a TAC case to determine why the corefiles are being generated. Often these corefiles are not complete though since the 30 GB /localdisk in 2.4+ hasn't been enough to save them. There are some changes coming around this but not sure if they have made it in to released patches yet.

Tried to install patch 2 on a fresh 2.7 deployment (nothing configured yet) and it failed due to not enough disk. I just wanted to share the error I got because looks like it is related to this issue about disk space

"Error while generating md5/sha256 crypto hash: No space left on device"

wondering, why cisco has not increase the size of 30 GB, we had tons of issues in the past on 2.2 version about that.

I opened a TAC Case to fix this.
