Do the math. df -hi will tell you the number of bytes and inodes used. Do a simple bytes/inodes and add about 10% just to be sure. That should take care of you. There are no "reasonable" values in my opinion. I have one client that makes a lot of files for robot machines (basically, text files). They don't get much longer than ~15K. If I redid their filesystem, I'd use 4000 bytes/inode. I have another client that's a graphic design firm, their server is filled with photo-quality tiffs and jpegs. I used 500000bytes/inode and the free space is still disappearing faster than the inodes are. If your server is 50% full, you should have enough data to make a reasonable estimate. Just pad it a little so you don't run out of inodes before you do free space. -- Bill Moran Potential Technologies http://www.potentialtech.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
