When we post articles on wordpress site, that will consume disk space on our web hosting. What I know, An inode is an unique index number given to the files and folders, we create under our cPanel account. Is our post on wordpress site also counted for inodes? I mean, does it add the number of inodes on our cpanel account? Thank you.
Wordpress posts and pages are stored in the database and not in the file system. So I would say "no" to your question. Unless somebody else knows otherwise?
It shouldn't, no. Inodes are strictly file-system, so a new file or folder will increase the number, but adding stuff to WP shouldn't. _HOWEVER_, if you add stuff like photos (which are uploaded to the server), videos or other media-files, THAT will add to the number. Same with new plugins and such.
