Back in the day XFS was great and worked excellently and was quite resilient, performant, etc. etc... until it wasn't. If it got too full or somehow corrupted beyond its capacity to recover then you were just screwed and it was very difficult to actually get your data back. Like it had a much higher threshold for being shitty and was great before you hit that threshold but after you hit it it was much worse than ext2/3 or whatever else I was using. Something around 80% full and it started to get awful and you risked losing your entire filesystem.<p>I'd have real reservations about knowingly using it again these days because of bad experiences, though this bias is based on really old experiences which are quite possibly no longer relevant.
