Hello, I just found user who has single folder (standard maildir format) that filled with over 8mil files and 800GB in the /tmp subdirectory of that folder:
Are they real files or hard links?
How would you distinguish a hard link from a “real file”?
ls -l will show the number of hard links to a file in the first column after the permissions (or it showed the number off files (including . and ..) inside a directory if it's a directory entry).
Ah, I misinterpreted the question then. You meant (I presume) “Are they 8 million distinct files, or 8 million hard links to a (much) smaller number of actual underlying inodes.”
So then my next question is (and I’m not intending to challenge you here, I’m just trying to get a better understanding of how dovecot works under the hood): where would these hard links come from? What does dovecot use hard links for?
