I switched to BTRFS for a year in between but looking at how fast it kills SSD, it wass not worthwhile. Stability wise, I only had 2 problems with NILFS, the first, which was fixed promptly, caused a total data lost because of how the cleaner scrub the disk (using the time), it scrubbed data from the future after time ran backward. Then the other problem was a kernel OOPS about a file from the debian APT cache, I deleted it and it runs just fine now, I couldn't take the backtrace. Performance wise, on SSD the filesystem is really fast and snappy, while on HDD, reads are really slow, booting takes 2 minutes instead of less than 10 seconds, however, once booted and everything is in cache, it is quite fast. Database loads, especially reads on HDD is the worst for NILFS. -- To unsubscribe from this list: send the line "unsubscribe linux-nilfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
