>For those of you that have been using the ext4 technology preview on CentOS 5.5, how has it panned out? Does it perform as expected? How do you feel the stability, creation of the FS and the administration of it is? Ideas and comments welcome. I've recently been using ext4 because I have servers with large(ish) storage volumes, and because I know that the next version of centos will support it better than 5.5. I only use it for storage, where I use rsync to copy terabytes of data to and from the servers. It works fine - it's been set and forget so far. Very fast read/write speeds.
