System and method for deploying servers in a distributed storage to improve fault tolerance

A system for deploying servers in a distributed storage to improve fault tolerance, the system comprising an installer implemented in a computing device comprising a processor, and any number of servers of the distributed storage, each server including at least one physical block device, the processor configured to:

• on a hardware server belonging to the distributed storage, install an OS on a virtual disk, wherein a virtual disk is represented by a file;
• put the file representing the virtual disk on which the OS is installed on the distributed storage;
• configure the hardware server belonging to the distributed storage so that two or more of the physical block devices of the hardware server are bootable by putting, on each physical block device of the two or more of the physical block devices, a boot component, and store at least one replica of the file representing the virtual disk on which the OS is installed on the hardware server, wherein the OS handles at least tasks for synchronizing replicas of the file representing the virtual disk on which the OS is installed;
• and
• configure the boot component on any one physical block device of the two or more of the physical block devices, the configuration of the boot component including enabling the boot component to perform at least accessing the distributed storage, retrieving the file representing the virtual disk on which the OS is installed from the distributed storage, mounting the virtual disk on which the OS is installed as a root file system of the OS, and booting the OS from the mounted virtual disk during a booting of the hardware server.

A non-transitory computer readable medium storing thereon computer executable instructions for deploying servers in a distributed storage to improve fault tolerance, including instructions for:

• on a hardware server belonging to the distributed storage, installing an OS on a virtual disk, wherein a virtual disk is represented by a file;
• putting the file representing the virtual disk on which the OS is installed on the distributed storage;
• configuring the hardware server belonging to the distributed storage so that two or more of the physical block devices of the hardware server are bootable by putting, on each physical block device of the two or more of the physical block devices, a boot component, and storing at least one replica of the file representing the virtual disk on which the OS is installed on the hardware server, wherein the OS handles at least tasks for synchronizing replicas of the file representing the virtual disk on which the OS is installed;
• and
• configuring the boot component on any one physical block device of the two or more of the physical block devices, the configuration of the boot component including enabling the boot component to perform at least accessing the distributed storage, retrieving the file representing the virtual disk on which the OS is installed from the distributed storage, mounting the virtual disk on which the OS is installed as a root file system of the OS, and booting the OS from the mounted virtual disk during a booting of the hardware server.
