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.

I've been using it for the same purpose on a volume that is ~2.4TB, rsyncing a few 100's of GB/day. Works better than tape. No issues so far (maybe 6 months or so).

Same story here. I'm building a new backup server from scratch (with no old data on it), and while ext3 is nice and stable it's also pretty slow when we start talking sevenish terabytes.
My main concern is all the writing on the interweb regarding running an fsck and a tune2fs after having formatted the filesystem to ext4; some say you should while some say it isn't necessary. Anyway, I get a bad block message when running fsck, and am not sure whether this is a interface problem between the chair and the monitor or something with the tech preview.
