And there are several reasons for that: That is totally understood. But I guess when your alloc space is nearing 90% of your disk capacity, and used space is sorta 80% or so of the alloc space, I guess it's a reasonable thing to expect that people should add a drive to the pool, which btrfs makes so easy. Given this, why do people complain about btrfs not being predictable when it comes to ENOSPC? Even with any other FS, I do think I'd not like my files to occupy more than 90% or so since even then defrag would probably not work. -- Shriramana Sharma ஶ்ரீரமணஶர்மா श्रीरमणशर्मा -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
