So - got a curly one.
Have a Dude CHR built off the OVA template on XCP-NG.
Has run "well enough" - but noticed after a couple of weeks away that some of my Functions had disappeared recently.
Digging in - I found my 64GB "disk" has 0B free, and that it appears that Dude is begining to eat RAM for storage (as would be expected) - hence the potential for loss.
OK, I though, delete some stuff and free some space, fix up shit and make a backup... But this has proved fruitless. The Space did not return.
Dude DB is ~ 800MB, backups on disk were totaling ~ 4GB. Dude files, less than 1GB total. After removing the "middle" backups, did an FTP dump from Dude to Synology - Total files copied ~ 3.6GB.
WTF has happened to the HDD space on the Dude. there are NOT 64GB of files on disk1, and we only keep 7 days of current backups on the VM - deleting the older ones. There IS free space - but why can the CHR not see it.
Are using an old version - 6.46.6 - as it is the only version that I know of that supports old and new ROS - as we have thousands of devices out there. Cranking them all up has been a slow process.
Any info on how to reclaim Space on a HDD would be very much appreciated - so we can avoid these issues in the future.
