Drbd manual resync

This option is available since DRBD resync-after res-name/volume Define that a device should only resynchronize after the specified other device. By default, no order between devices is defined, and all devices will resynchronize in parallel.  · When DRBD detects that its peer node is down (either by true hardware failure or manual intervention), DRBD changes its connection state from Connected to WFConnection and waits for the peer node to re-appear. The DRBD resource is then said to operate in disconnected mode. In disconnected mode, the resource and its associated block device are fully usable, and may be Estimated Reading Time: 8 mins.  · To make the synchronization slow down and let the application proceed, DRBD has the dynamically adaptive resync rate controller. It is enabled by default with , and disabled by default with To explicitly enable or disable, set c-plan-ahead to 20 (enable) or 0 (disable).

DRBD allows "normal" application I/O even during a resync. If the resync takes up too much bandwidth, application I/O can become very slow. This parameter allows to avoid that. DRBD (Distributed Replicated Block Device) is a really cool cluster solution to have radundant data on two or more nodes. Everybody know RAID, DRBD is like RAID 1 over network. Install DRBD virtual package (This will work on Debian and Ubuntu). This option is available since DRBD resync-after res-name/volume Define that a device should only resynchronize after the specified other device. By default, no order between devices is defined, and all devices will resynchronize in parallel.

Oct When resource is awaiting resynchronization, but the peer node has suspended it that it has been manually detached using drbdadm detach. Please check the DRBD manual and enable them, if they make sense in your setup. before-resync-target "/usr/lib/drbd/www.doorway.ru -p please see the www.doorway.ru manual page for more information. When resource is awaiting resynchronization, but the peer node has suspended it for any.
