Hi Guys, i just put a little Cluster in Testing with XCP 1.6... The most strange thing i noticed is the really really slow imports and explorts of the xen-api...
When migrating VM's from my 1.1 to the 1.6 Cluster i do export them onto a NFS Share with one pool, and re-import them on the 1.6 pool. Export on the 1.1 Cluster is really ok. I think about 200-300mbit/s net, maybe the NFS Server is here the limiting Component. Import/Export in/from the 1.6 Cluster is a hell. Yesterday it took my awesome 487 Minutes to export a VM of roughly 40gb: [root@xcp2 615824d1-1aeb-7054-cc07-417ba25c78f0]# time xe vm-export vm=rsa2 filename=rsa2-test-unc.xva compress=false Export succeeded real 487m33.284s user 0m25.810s sys 6m26.960s [root@xcp2 615824d1-1aeb-7054-cc07-417ba25c78f0]# ls -lah|grep rsa2 -rw------- 1 nfsnobody nfsnobody 38G 18. Dez 04:50 rsa2-test-unc.xva Exporting that VM from the Other Cluster takes about 35 Minutes.. Network + Hardware is fine... Inside a VM on the 1.6 Cluster I get about 55mb/s Disk performance.. and about 45mb/s to the NFS Server. I've spend quite some time now to find out where the Bottleneck ist.. Any Ideas on that? thanks, Bastian _______________________________________________ Xen-api mailing list [email protected] http://lists.xen.org/cgi-bin/mailman/listinfo/xen-api
