I have a btrfs filesystem mounted in two locations as two subvolumes: /dev/mapper/luks-blah / btrfs subvol=/rootvol 1 1 /dev/mapper/luks-blah /var/lib/libvirt/images btrfs nodatasum,nodatacow,subvol=/images.libvirt 1 2 However, a file under the second mount is getting seriously fragmented. It started out with a few dozen extents (reasonable for a several gigabytes), now it's 11000 and counting, after an application started pounding on it with a bit of threaded O_DIRECT random I/O. 3.3.1-5.fc16.x86_64 Any hints? -- 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
