Looks like /tmp is only 121MB in the file system while the rest is being used by RAM. zroot/tmp 121M 721M 121M /tmp I do have this line in fstab: tmpfs /tmp tmpfs rw,nosuid,mode=01777 0 0 It still doesn't help in any case why deleting files strikes them off the file list but doesn't touch the disk itself? Hopefully there will a solution down the line and hopefully I will learn something too.... currently my mind seems to be blocked however, in which direction to even approach this problem and especially what to look at :-(
