I've been following bcache's development, but it seems to have stalled a bit. I've got a 240G Samsung 470/810 that I'd like to use for this. Also I was wondering if anyone has any tips on the best (or their preferred) way to set up a "big" raid6 array with a single filesystem. I'm probably going to stick with XFS, but I'm not married to it, if there's something better for a big media (audio, video, disk images, backups, etc) volume I'd love to hear about it. -- Thomas Fjellstrom thomas@fjellstrom.ca
