A Linux kernel patch set has been proposed for the implementation of the distributed replicated block device DRBD 9, which allows the creation of a RAID-1 array made up of network-mirrored storage devices connected to different systems. The driver is initially planned to be tested in the linux-next branch and prepared for integration into the Linux kernel 7.2. <\/p>\n

The old version of DRBD has been included in the kernel since version 2.6.33, released 16 years ago. The existing kernel code is based on the DRBD 8 branch, which is significantly different from the DRBD 9 branch released in 2015 and is not protocol-compatible. As a result, the DRBD 9 branch has evolved as a separate external module, not synchronized with the module in the main kernel. The existing implementation of DRBD in the kernel has been maintained separately and is 10-15 years behind the current DRBD code base. The proposed patches are created to close the gap that has formed. <\/p>\n
