How to remove largefiles from Mercurial repo

See also this question.

Without knowing what I was doing, I enabled the largefiles extension, committed a file and pushed it to kiln. Now I know the error of my ways, and I need to permanently revert this change.

Which filesystem for large LVM of disks (8 TB)?

I have a Linux server with many 2 TB disks, all currently in a LVM resulting in about 10 TB of space. I use all this space on an ext4 partition, and currently have about 8,8 TB of data.

Problem is, I often get errors on my disks, and even if I replace (that is to say, I copy the old disk to a new one with dd then i put the new one in the server)…
