Chuck: 8.0.13 is a bugfix release, please see the following changelog. Furthermore, please consider that DRBD is completely useless in a production environment as of version 8.0.11. Every recent server has a battery backed write cache for it's disks and I don't see the point of forcing LTS users to take a slowdown of an order of magnitude (~3KB/s vs ~3MB/s) for applications writing in tiny increments (think INSERT statements of a database).
From: http://git.drbd.org/?p=drbd-8.0.git;a=blob_plain;f=ChangeLog;hb=HEAD 8.0.13 (api:86/proto:86) -------- * Fixed online resizing if there is application IO on the fly when the resize is triggered. * Fixed online resizing if it is triggered from the secondary node. * Fixed a possible deadlock in case "become-primary-on-both" is used, and a resync starts * Fixed the invocation of the pri-on-incon-degr handler * Fixed the exit codes of drbdsetup * sock_create_lite() to avoid a socket->sk leak * Auto-tune socket buffers if sndbuf-size is set to zero * Made it to compile on Linux-2.6.26 8.0.12 (api:86/proto:86) -------- * Corrected lock-out of application IO during bitmap IO. (Only triggered issues with multi-terrabyte volumes) * If an attach would causes a split-brain, abort the attach, do not drop the connection * A node without data (no disk, no connection) only accepts data (attach or connect) if that data matches the last-known data * Fixed various race conditions between state transitions * Various bugfixes to issues found by using the sparse tool * Corrected the exit codes of drbdsetup/drbdadm to match the expectations of dopd (drbd-outdate-peer-daemon) * Corrected the online changing of the number of AL extents while application IO is in flight. * Two new config options no-disk-flushes and no-md-flushes to disable the use of io subsystem flushes and barrier BIOs. * Make it compile on Linux-2.6.25 * Support for standard disk stats * Work on stalling issues of the resync process * drbdsetup /dev/drbdX down no longer fails for non-existing minors * Added wipe-md to drbdadm -- DRBD 8.0.11 is unusably slow https://bugs.launchpad.net/bugs/288226 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
