Hello Everyone,
We are setting up an 8.4 cluster (elrepo RPMs -- drbd84-utils-8.4.4-2.el6.elrepo.x86_64.rpm<http://mirror.symnds.com/distributions/elrepo/elrepo/el6/x86_64/RPMS/drbd84-utils-8.4.4-2.el6.elrepo.x86_64.rpm> and kmod-drbd84-8.4.4-1.el6.elrepo.x86_64.rpm<http://mirror.symnds.com/distributions/elrepo/elrepo/el6/x86_64/RPMS/kmod-drbd84-8.4.4-1.el6.elrepo.x86_64.rpm>) on RHEL 6. I have two SuperMicro storage boxes with 2 x 4 core Xeons, 48GB RAM, LSI 9280-24i-4e cards, 2 x 512GB SSDs set up as a RAID1 CacheCade, 21 x 2TB WD RE4 drives set up in a 36TB RAID50, and 10GbE over fiber connecting the two machines. DRBD volume is on top of an LVM logical volume. For some reason, a few hours after starting the initial sync, network activity between the boxes dies down and DRBD shows that the nodes are syncing but the numbers are not changing. I don't see any errors anywhere in the logs. I am running the same RPMs, same version of RHEL, and same kernel, and a largely similar (smaller) setup on other systems and do not see the same problem. Thanks, Michael ______________________________________________________________________________________ Michael Kushnir System Architect Communications Engineering Branch Lister Hill National Center for Biomedical Communications National Library of Medicine 8600 Rockville Pike, Building 38A, Floor 10 Besthesda, MD 20894 Phone: 301-435-3219 Email: [email protected]<mailto:[email protected]>
