Filesystems aged like sharp cheeseFilesystems aged like sharp cheesePosted Jul 20, 2006 23:49 UTC (Thu) by efexis (guest, #26355)In reply to: Filesystems aged like sharp cheese by Max.Hyre Parent article: The 2006 Linux Filesystems Workshop (Part III)
The problem is when you want to test a new feature, such as a new algorithm for deciding where to place new blocks on the disk... the filesystem has to be created using this code. Grabbing an old filesystem that wasn't created using this code is completely useless.
You need to replay all the actions, all the file creates, writes, moves, deletes etc, in an order they would actually happen, to see the result.
