Rosetta seems to be ignoring the 20GB limit I've set, as shown in the attachments. In consequence, the relevant filesystem eventually becomes 100% full and everything stops. Is there a way I can stop this from happening? Or should I just disable Rosetta and allow LHC tasks instead?
Is it possible that the Rosetta data was downloaded before you changed the disk usage settings, and now those files are just stuck there wasting storage space? Under normal circumstances, you'd get a notice in BOINC if a task requires more disk space than is available, e.g. "Rosetta needs 25GB of disk space, but only 20GB is available." You could try manually removing Rosetta data under ProgramData/BOINC/projects/ to see if that helps, but if it is ignoring preferences, I suppose it would just download it all again.
Which version of BOINC are you running? And do you have a separate disk partition for BOINC data, or is it on the primary / C drive?
No, all Rosetta data was cleared (along with everything else) when the (Linux root) disk filled up, and I had to do a "Sychronise with Charity Engine" to get new jobs.
Since then I've had to do a "Reset Project" to clear all Rosetta data when the disk is about to fill.
I'm using version 7.16.6 (x64) on Ubuntu 20.04.03 LTS (package 7.16.6+dfsg-1). It doesn't offer any option about where data should be stored.
Oh .. and I occasionally get a notice like: "Rosetta needs 25GB of disk space, but only 20GB is available." But sometimes I don't, and that's when the issue arises.
