This improves performance when reading sparse files. GlusterFS now supports the SEEK operation as well. Linux kernel 4.5 comes with an improved FUSE module where lseek() can be used. QEMU can now detect holes in VM images when using the Gluster-block driver. +*Limitations:* The deprecated stripe functionality has not been extended with SEEK. SEEK for sharding has not been implemented yet, and is expected to follow later in a 3.8 update (bug 1301647). NFS-Ganesha will support SEEK over NFSv4 in the near future, posisbly with the upcoming nfs-ganesha 2.4. + ## Bugs addressed A total of 1685 (FIXME) patches has been sent, addressing 1154 (FIXME) bugs: |
