Hello,
I'm having a local partition full problem
my 100Gb local fs is 95% full, but when I use ncdu it says I roughly use 30Gb
after checking with ncdu, I didn't find any abnormal artefact or tmp files, nothing to delete. To my understanding, 60Gb are ghost data that I can't find.
I looked at various posts about that and unfortunately found nothing that matches my usecase, I only found how to truncate log files ...
What could be wrong ? How to purge this ?
