Hi, Running a 3.19 Ubuntu kernel,
I'm currently budling a RAID-1 BTRFS set for which every underlying device is a LUKS-encrypted device itself built out of a bcache device comprised of a mechanical HD partition + an SSD cache partition. Looks like it's working. BUT I see that BTRFS decides by itself to mount with the "ssd" option as bcache makes it think the device is not "rotational". However I feel that a mechanical HD plus SSD bcache should probably not be "SSD-optimized" as the underlying storage is indeed mechanical and bcache already manages the SSD part optimization by itself - and I'm afraid the "SSD optimization" could actually cause the mechanical storage to end up being much more fragmented than it should... So the question is : Is there a mount option such as "nossd" that I could use to inhibit the automatic SSD "choice" that BTRFS makes ? TIA, kind regards. -- Swâmi Petaramesh <sw...@petaramesh.org> http://petaramesh.org PGP 9076E32E -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in
