CONFIG_MD_CLUSTER: Cluster Support for MD

General informations

The Linux kernel configuration item CONFIG_MD_CLUSTER has multiple definitions:

Cluster Support for MD found in drivers/md/Kconfig

The configuration item CONFIG_MD_CLUSTER:

• prompt: Cluster Support for MD
• type: tristate
• depends on: ( CONFIG_BLK_DEV_MD ) && ( CONFIG_DLM )
• defined in drivers/md/Kconfig
• found in Linux kernels: 4.15–4.20, 5.0–5.19, 6.0–6.8, 6.9-rc+HEAD
• modules built: md-cluster

Help text

Clustering support for MD devices. This enables locking and synchronization across multiple systems on the cluster, so all nodes in the cluster can access the MD devices simultaneously.

This brings the redundancy (and uptime) of RAID levels across the nodes of the cluster. Currently, it can work with raid1 and raid10 (limited support).

If unsure, say N.

Cluster Support for MD (EXPERIMENTAL) found in drivers/md/Kconfig

The configuration item CONFIG_MD_CLUSTER:

• prompt: Cluster Support for MD (EXPERIMENTAL)
• type: tristate
• depends on: ( CONFIG_BLK_DEV_MD ) && ( CONFIG_DLM )
• defined in drivers/md/Kconfig
• found in Linux kernels: 4.1–4.14
