上下文：我有一个proxmox集群，其卷组与drbd共享的VM-KVM。
我有一个drbd的问题。 事实上，当一个节点断开连接时，不同节点之间的关联链路被中断。 影响是：
我停止正在运行的虚拟机（因为：错误：模块drbd正在使用）我禁用vg（与vgchange -an）我重新启动drbd服务和重新同步运行
configuration是：
/etc/drbd.conf：
# You can find an example in /usr/share/doc/drbd.../drbd.conf.example include "drbd.d/global_common.conf"; include "drbd.d/*.res"; Global_common.conf：
global { usage-count no; } common { protocol C; startup { degr-wfc-timeout 120; # become-primary-on proxmox001; become-primary-on both; } disk { } net { allow-two-primaries; after-sb-0pri discard-zero-changes; after-sb-1pri discard-secondary; after-sb-2pri disconnect; } syncer { verify-alg md5; rate 30M; } }
R0.res：
resource r0 { protocol C; on proxmox001 { device /dev/drbd0; disk /dev/mapper/pve-lv_data; address 192.168.0.1:7788; meta-disk internal; } on proxmox002 { device /dev/drbd0; disk /dev/mapper/pve-lv_data; address 192.168.0.2:7788; meta-disk internal; } }
当物理主机不稳定时，我丢失了drbd链接。
在正常的时候，/ proc / drbd：
GIT-hash: 83ca112086600faacab2f157bc5a9324f7bd7f77 build by root@proxmox001, 2013-04-24 12:55:32 0: cs:Connected ro:Primary/Primary ds:UpToDate/UpToDate C r----- ns:421142 nr:55715 dw:8498959 dr:10994034 al:1144 bm:420 lo:0 pe:0 ua:0 ap:0 ep:1 wo:b oos:0
而一个不稳定的，/ proc / drbd返回：
cs:Standalone or cs:WFConnection st:Secondary/Unknown
而当我重新启动DRBD同步，我有一个错误UpToDate或
ERROR: Module drbd is in use proxmox
我尝试不同的testing，然后谷歌build议：

但是我总是生产中断…
你有任何解决scheme绕过这个问题？
非常感谢 ！
编辑：
如果我将global_common文件configuration中的磁盘块replace为：
disk { fencing resource-only; }
如果在一台主机上有任何正在运行的虚拟机，我只需要重新启动drbd来重build关联同步链接。
但是，如果我有两台或所有主机上运行虚拟机，我已经与顶级线程相同。
谢谢
