kandi X-RAY | windrbd Summary
WinDRBD is a port of Linbit’s Distributed Replicated Block Device Linux driver to Microsoft Windows. Technically it is a thin compatibility layer that maps Linux specific kernel API calls to the Microsoft Windows NT Kernel API. DRBD itself is used to build High Availability clusters by replicating contents of block devices over a network to (up to 31) other nodes. WinDRBD is based on DRBD 9. It was originally started by Korean company Mantech and was later rewritten by an Austrian programmer called Johannes Thoma for Linbit. DRBD devices are exported as SCSI disks as soon as the resource becomes primary and can be partitioned and formatted with the standard Windows tools (diskpart, partition editor in control panel).

QUESTION
WinDRBD's progress is only visible when syncing. But I'd like to know how far has gone if the out-of-sync remains.
...ANSWER
Answered 2021-Sep-13 at 22:09When a resource becomes disconnected, the out-of-sync
counter will begin to increment on the peer that is currently Primary. When the resource reconnects, the bitmaps (stored in DRBD's metadata) are compared to determine which blocks became out-of-sync
while disconnected, and proceeds to resync those blocks in the background. Any writes that occur during a background resync are immediately replicated, and if that write happens to touch a block that's a part of the background resync, it's removed from the resync queue (since it was updated by the foreground replication).
QUESTION
I help you....
While using WinDRBD to connect two computers, one computer suddenly shutdown.
The shutdown side was secondary ( For convenience, let's call the shutdown Node2 )

Answered 2021-Sep-09 at 13:58Hi are you running as Administrator? You have to for drbdadm commands that modify the configuration. Error 5 looks like Permission denied error to me.
