missing gigs of disk space - 11/13/15 06:50 PM
I've ran into this problem on a larger scale but lacked the time to investigate it. Now I'm seeing smaller examples on a larger scale and have decided to try to figure it out.
These two computers were imaged from the same DMG and have been in use for a few months. Users have their home folder on another partition, allowing me to nuke the OS partition and reimage it without affecting user data. So nothing the (non-admin) users do should be able to make much of an impact on usable space. My having partitioned the drives (SSDs) means I have a hard limit on space on the system volume, and I'm trying to not use more than I have to, so more is available for the user home folders on the other partition.
This computer has 17gb free:
This computer has less than 8gb free:
The question is... WHY? Where did 10 gig of disk space go?
Removing folders with less than 100MB makes it easier to compare
There is a VERY small increase in used space, a few hundred MB, but it's showing a total difference of 10GB.
My only current theory on this is there's a folder somewhere that has a lot of small files in it, and it's the folder size causing this problem. The last time I ran into this, over 100GB of space was missing, and a safe boot fixed it. (and it was NOT due to fsck, I had already repaired the disk, it was deleting temp files or something somewhere)
Ideas?
