Hi Steffen, Seem that you have multicast errors/hang which cause corosync error. What physicals switchs do you use ? (I ask this because we have found a multicast bug with a feature of current kernel and cisco swithcs)
2013/3/12 Steffen Wagner < [email protected] > Hi, I had a similiar problem with 2.2 I had rgmanager for HA features running on high end hardware (Dell, QNAP and Cisco). After about three days one of the nodes (it wasnt always the same!) left quorum (log said something like 'node 2 left, x nodes remaining in cluster, fencing node 2.'. After then always the node was successfully fenced... so i disabled fencing and changed it to 'hand'. Then the node didnt shut down anymore. It remained online with all vms, but the cluster said the node was offline (at reboot the node stuck at pve rgmanager service, only hardreset was possible). In the end i disabled HA and ran the nodes now only in cluster mode without fencing... working until now (3 months) without any problems... a pity, because i want to use HA features, but dont know whats wrong. My network setup is similiar as Fabio's. I'm using VLANs one for the storage interface and one for the other..... Until now i think i stay at 2.2 and do not upgrade to 2.3 until everyone in the maillist is happy :-) Mit freundlichen Grüßen, Steffen Wagner -- Im Obersteig 31 76879 Hochstadt/Pfalz E [email protected] M 01523/3544688 F 06347/918474 Fábio Rabelo < [email protected] > schrieb: >2013/3/12 Andreu Sànchez i Costa < [email protected] > > >> Hello Fábio, >> >> Al 12/03/13 01:00, En/na Fábio Rabelo ha escrit: >> >> >> 2.3 do not have the reliability 1.9 has !!!! >> >> I am struggling with it for 3 months, my deadline are gone, and I cannot >> make it work for more than 3 days without an issue ... >> >> >> I cannot give my opinion about 2.3 but with 2.2.x it works perfectly, I >> only had to change elevator to deadline cause CFQ had performance problems >> with our P2000 iSCSI array disk. >> >> As other list members asked, what are your main problems? >> >> >I already described the problems several times here . > >This is a five node cluster, motherboards dual opteron from Supermicro . > >Storage uses the same motherboard as the five nodes, but with a 16 3,5 HD >slots, with 12 occupied by WD enterprise disks . > >Storage runs Nas4Free .
