Hi Rorthais， Thank you for your help.
The replication works at that time. I try again today. (1) If I run "ifup enp0s3" in node2, then run "ifdown enp0s3" in node1, the switchover issue could be reproduced. (2) But if I run "ifup enp0s3" in node2, run "pcs resource cleanup mastergroup" to clean the VIP resource, and there is no Failed Actions in "pcs status", then run "ifdown enp0s3" in node1, it works. The switchover could happened again. Is there any parameter to control this behaviors so that I don't need to execute the "pcs cleanup" command every time? -----邮件原件----- 发件人: Jehan-Guillaume de Rorthais [mailto:j...@dalibo.com] 发送时间: 2018年4月25日 18:39 收件人: 范国腾 <fanguot...@highgo.com> 抄送: Cluster Labs - All topics related to open-source clustering welcomed <users@clusterlabs.org>; 李梦怡 <limen...@highgo.com> 主题: Re: [ClusterLabs] the PAF switchover does not happen if the VIP resource is stopped On Wed, 25 Apr 2018 08:58:34 +0000 范国腾 <fanguot...@highgo.com> wrote: > > Our lab has two resource: (1) PAF (master/slave) (2) VIP (bind to the > master PAF node).
