Dear WinDRBD users, In this release of WinDRBD where we put lots of efforts to make WinDRBD behave more stable under memory pressure. The older WinDRBD releases gave up without retrying when (for example) kmalloc() could not allocate memory. The new version contains a retry loop in the memory allocation code which is also the behaviour of the Linux kernel. So (for example) resources suddenly becoming Diskless on memory pressure should not happen any more.
Also a drbdadm hang on becoming Primary introduced with 1.1.8 has been fixed. I also updated the stable branch of WinDRBD with this release so for new deployments please use this 1.1.10 release. Old deployments should be upgraded if you are affected by memory pressure issues but otherwise there is no urgent need to upgrade now. For more details (as always) see: https://github.com/LINBIT/windrbd/blob/windrbd-1.1/WHATSNEW.md An evaluation installer (self signed driver) can be downloaded from the LINBIT Website: to use this driver you have to put your Windows machine into test mode (bcdedit /set TESTSIGNING YES and reboot). It can be downloaded from: https://linbit.com/linbit-software-download-page-for-linstor-and-drbd-linux-driver/ Best regards, - Johannes
