I decided that I would try out 2.5.44, and I noticed that htree was merged. If I don't do the tune2fs -O dir_index, and e2fsck -D, the (exisintg) fs won't use htree, right? Once I do the tune2fs and e2fsck, will I still be able to go back to a non-htree kernel if needed? (Will a htree-ized fs work on a non-htree kernel?) I'm guessing that it won't. I've seen a 2.4 htree patch; has that been updated to be at the same point as what was merged into 2.5? (if so, link please) Thanks, Chris -- Chris PeBenito "Engineering does not require science.

The worst that happens is that if you turn off dir_index and then fsck, you get a lot of harmless noise about directories with the hashed dir flag set but the filesystem doesn't have dir_index. J
