I think originally needs most of metdata in memory. I'm not understanding why btrfs check won't use swap like at least xfs_repair and pretty sure e2fsck will as well. Using 128G swap on nvme with original check is still gonna be faster than lowmem mode. -- Chris Murphy -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
