I can confirm that drbd8-utils 2:8.4.3-0ubuntu0.12.04.2~rc4 works fine, at least for me.
I put one node to standby, installed drbd8-utils 2:8.4.3-0ubuntu0.12.04.2~rc4, did not change drbd.conf, brought node up again and migrated all resources to that node. Everything is working as expected: Master/Slave Set: ms_drbd_r0 [p_drbd_r0] Masters: [ www6b ] Slaves: [ www6a ] # uname -a Linux www6b 3.5.0-48-generic #72~precise1-Ubuntu SMP Tue Mar 11 20:09:08 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux # cat /proc/drbd version: 8.3.13 (api:88/proto:86-96) srcversion: C0F510A918B92928FB51EE3 0: cs:Connected ro:Primary/Secondary ds:UpToDate/UpToDate C r----- ns:72 nr:788 dw:860 dr:7561 al:0 bm:8 lo:0 pe:0 ua:0 ap:0 ep:1 wo:f oos:0 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1185756 Title: drbd8-utils not compatible with linux-lts-raring kernel in 12.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/drbd8/+bug/1185756/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
