Can we sync up w/ how you are calculating these results as they do not
match our results.
I see each job consuming about 215M of space, we are close on stackviz
being 83M. Oddly I don't see atop.bin.gz in our calculations so I'll have
to look into that.
I've checked it directly using du on the logserver. By 1.2 GB I meant the
aggregate of the 8 jobs running for a single patchset. PS26 is currently
using 2.5 GB and had one recheck.
About the atop.bin.gz file:
# find . -name atop.bin.gz -exec du -sh {} \;

Can I safely delete all .stackviz directories? I guess that would give us
some breathing room.
Yup, go for it

Each job reports the size of the logs e.g. [1]
