Re: [ClusterLabs] [Cluster-devel] DLM connection channel switch take too long time (> 5mins)

Hello David, If sctp implementation did not fix this problem, there is any workaround for a two-rings cluster? Could we use TCP protocol in DLM under a two-rings cluster to by-pass connection channel switch issue? Thanks Gang >>> >> I use active rrp_mode in corosync.conf and reboot the

Thanks Rorthais, Got it. The following command could make sure that it move to the master if there is no standby alive: pcs constraint colocation add pgsql-ip-stby1 with slave pgsql-ha 100 pcs constraint colocation add pgsql-ip-stby1 with pgsql-ha 50 -邮件原件- 发件人: Jehan-Guillaume de

Re: [ClusterLabs] copy file

Hi, thanks for advice and your intrest. We would use oracle database over DRBD. Datafiles (and control and redo files) will be on DRBD. FRA also (on an other DRBD device). But we are new in DRBD, and DRBD is also a component what can fails. We plan a scenario to recover the database without DRBD

Hi Feldhost, I use active rrp_mode in corosync.conf and reboot the cluster to let the configuration effective. But, the about 5 mins hang in new_lockspace() function is still here. Thanks Gang >>> > Hi, so try to use active mode. > >

Hello Gang He, which type of corosync rrp_mode you use? Passive or Active? Did you try test both? Also, what kernel version you use? I see some SCTP fixes in latest kernels. > On 8 Mar 2018, at 08:52, Gang He wrote: > > Hello list and David Teigland, > > I got a problem under
