I penciled one session for "FS stable backporting (and other LTS woes)". I made it a cross FS/IO session so we can have this session in the big room and you are welcome to pull this discussion to any direction you want. > > (I /am/ willing to have a "Online fs metadata reconstruction: How does > it work, and can I have some of what you're smoking?" BOF tho) > I penciled a session for this one already. Maybe it would be interesting for the crowd to hear some about "behind the scenes" - how hard it was and still is to pull off an engineering project of this scale - lessons learned, things that you might have done differently.
