I've got a fairly long lived CentOS server that stubbornly stopped installing updates because the HDD is full.
Can someone share their favourite way to determine where disk space is being used up on a system?
For example, on Windows I'd use Wiztree/Treesize/Windirstat. On Linux desktop I've been using Gnome Disk Usage Analyzer (aka Baobab) https://wiki.gnome.org/Apps/DiskUsageAnalyzer.
But I'm not sure what the best solutions are in cases where there's no GUI available. I could always mount / over SSH and use Baobab to crawl the remote filesystem, but that seems less than optimal 🤔
