Hi All, I''m successfully using drbd on xen dom0''s across a 2 machine cluster. However I have one domU that refuses to start on one of the machines, but starts find on the other. Config files for domU and drbd are identical. Not sure where to start looking to diagnose the problem x-host-3:/etc/xen # xm create n-monitor Using config file "/etc/xen/vm/n-monitor". Started domain n-monitor x-host-2:~ # xm create n-monitor Using config file "/etc/xen/vm/n-monitor". Error: Device 51712 (vbd) could not be connected. /etc/xen/scripts/block failed; error detected. cat /proc/drbd version: 8.0.6 (api:86/proto:86) SVN Revision: 3048 build by phil@mescal, 2007-09-03 10:39:27 0: cs:Connected st:Primary/Secondary ds:UpToDate/UpToDate C r--- ns:67460 nr:42100 dw:109560 dr:276 al:8 bm:13 lo:0 pe:0 ua:0 ap:0 resync: used:0/31 hits:79 misses:13 starving:0 dirty:0 changed:13 act_log: used:0/257 hits:14489 misses:8 starving:0 dirty:0 changed:8 1: cs:Connected st:Secondary/Primary ds:UpToDate/UpToDate C r--- ns:0 nr:349880 dw:349880 dr:0 al:0 bm:7 lo:0 pe:0 ua:0 ap:0 resync: used:0/31 hits:67 misses:7 starving:0 dirty:0 changed:7 act_log: used:0/127 hits:0 misses:0 starving:0 dirty:0 changed:0 2: cs:Connected st:Secondary/Primary ds:UpToDate/UpToDate C r--- ns:0 nr:16956532 dw:16956532 dr:0 al:0 bm:231 lo:0 pe:0 ua:0 ap:0 resync: used:0/31 hits:0 misses:0 starving:0 dirty:0 changed:0 act_log: used:0/127 hits:0 misses:0 starving:0 dirty:0 changed:0 x-host-2:~ # cat /etc/xen/vm/n-monitor name="n-monitor" ostype="opensuse" uuid="43f11902-dfef-345e-e523-0e68c26a6e0b" memory=1024 vcpus=2 on_crash="destroy" on_poweroff="destroy" on_reboot="restart" localtime=0 kernel = "/boot/vmlinuz-xen" ramdisk = "/boot/initrd-xen" root="/dev/xvda1" disk=[ ''drbd:n-monitor,xvda,w'', ] vif=[ ''mac=00:16:3e:41:89:24,bridge=xenbr0'', ''mac=00:16:3e:41:89:25,bridge=xenbr1'' ] vfb=[''type=vnc,vncunused=1''] resource n-monitor { protocol C; net { allow-two-primaries; } on x-host-2 { device /dev/drbdr2; disk /dev/sdb3; address 10.1.1.111:7790; flexible-meta-disk internal; } on x-host-3 { device /dev/drbd2; disk /dev/sdb3; address 10.1.1.112:7790; meta-disk internal; } } _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
