How to check DRBD version?
You can monitor the DRBD status by using one of two methods:
- service drbd status.
- cat /proc/drbd.
What is DRBD in Linux?
DRBD (Distributed Replicated Block Device) is a Linux-based software component that facilitates the replacement of shared storage systems by networked mirroring. DRBD makes it possible to maintain consistency of data among multiple systems in a network.
What is Linstor?
LINSTOR is open-source software designed to manage block storage devices for large Linux server clusters. LINSTOR® is open-source software designed to manage block storage devices for large Linux server clusters.
Is DRBD synchronous?
DRBD supports both synchronous and asynchronous write operations, which will be further discussed below in relation to the three protocol setups.
What is Linbit?
www.linbit.com/drbd/ DRBD is a distributed replicated storage system for the Linux platform. It is implemented as a kernel driver, several userspace management applications, and some shell scripts.
What is the purpose of DRBD in Linux?
DRBD (Distributed Replicated Block Device) is a Linux-based software component that facilitates the replacement of shared storage systems by networked mirroring. DRBD makes it possible to maintain consistency of data among multiple systems in a network. DRBD also ensures high availability ( HA) for Linux applications.
What is DRBD ( distributed replicated block device )?
DRBD (Distributed Replicated Block Device) is a Linux-based software component that facilitates the replacement of shared storage systems by networked mirroring.
Who is the creator of the DRBD software?
DRBD is a registered trademark of LINBIT Information Technologies GmBH, headquartered in Vienna, Austria. The software has been released under the GNU GPL (General Public License) and can be freely distributed and modified within the limitations of the license agreement.
How is DRBD used in high availability clusters?
DRBD is traditionally used in high availability (HA) computer clusters, but beginning with DRBD version 9, it can also be used to create larger software defined storage pools with a focus on cloud integration. The DRBD kernel driver presents virtual block devices to the system. It is an important building block of the DRBD.
