so we are stuck with this closed source system that keeps on adding folders to one directory, and it's going to hit the 32k limit soon because it's ext3. and that folder is expected to have +100k folders very soon too.
it's 2.6.24-27-xen x86_64 Ubuntu 8.04.4 LTS
ext4 isn't supported, reiserfs is problematic, we're now trying xfs. is there anyone that can suggest us the best way forward (ideally from experience) given the constants above ?
