Somehow I was very over my disk limit (Preferences state that I am currently using 499.6 GB?), and now the tool execution is on hold. However, I followed the wiki and video (https://wiki.galaxyproject.org/Learn/ManagingDatasets) and permenantly deleted everything, and I'm still seeing the high disk usage hours later. What else can I do?
Also, I'm unclear how I ended up over my quota in the first place - I'm using Galaxy as part of a bioinformatics class and am very new to it. I was having trouble converting a text file with SRR accession numbers to FASTQ on Thursday, but from my (now purged) history, it looked like maybe some of these operations completed after I closed my session? I don't know, I'm confused.
