Thanks Lars for replying. I don't have problem in upgrading DRBD to 8.4 but I am worried about data. Since two nodes are out of sync will upgrade on secondary (removing 8.3 and installing 8.4) will force sync to finish? If it doesn't happen how should I approach primary upgrade?
From: [email protected] To: [email protected] Subject: DRBD 8.3.13 Sync getting stalled with RHEL 6 Date: Mon, 21 Oct 2013 19:04:04 +0530 Hi Friends, I have already a DRBD 8.3.13 setup running on RHEL 6 servers. After recent kernel upgrade to 2.6.32-358.18.1.el6.x86_64, DRBD sync got stalled on the server. I have tried to invalidate secondary and start the sync but sync is alway 100% mark. [root@PdCuLx0503p ~]# cat /proc/drbd version: 8.3.13 (api:88/proto:86-96) GIT-hash: 83ca112086600faacab2f157bc5a9324f7bd7f77 build by dag@Build64R6, 2012-09-04 12:06:10 0: cs:SyncSource ro:Primary/Secondary ds:UpToDate/Inconsistent C r----- ns:92498284 nr:0 dw:92499372 dr:170166401 al:114209 bm:70 lo:0 pe:0 ua:0 ap:0 ep:1 wo:b oos:44 [===================>] sync'ed:100.0% (44/276)K finish: 8:25:29 speed: 0 (0) K/sec (stalled) [root@PdCuLx0503p ~]# I tried to install same version on non production RHEL6 servers but in that also Initial syncs are getting stalled. Is 8.3.13 supported on kernel 2.6.32-358.18.1 and later?
