I was wondering about whether using options like "autodefrag" and "inode_cache" on SSDs. On one hand, one always hears that defragmentation of SSD is a no-no, does that apply to BTRFS's autodefrag? Also, just recently, I heard something similar about "inode_cache". On the other hand, Arch BTRFS wiki recommends to use both options on SSDs http://wiki.archlinux.org/index.php/Btrfs#Mount_options So to clear things up, I ask at the source where people should know best. Does using those options on SSDs gives any benefits and causes non-negligible increase in SSD wear? -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
