Dear All, I'm trying to migrate online a VPS but I keep seeing the following error:
============================ Live migrating container... Copying top ploop delta with CT suspend Sending /vz/private/10004/root.hdd/root.hdd Setting up checkpoint... suspend... get context... Checkpointing completed successfully Dumping container Setting up checkpoint... join context.. dump... Can not dump container: Invalid argument Error: iptables-save exited with 1 Checkpointing failed Error: Failed to dump container Resuming... ============================ Notes: 1) The container keeps working on the original node after the aborted attempt to migrate. 2) I have tried to manually issue `iptables-save` on the destination node and it works. 3) I know that the destination node must have loaded all the required IPtables modules. These are the relevant lines: ==== ORIGIN NODE ==== [root@node16 /]# uname -a Linux node16.xxxxx.com 2.6.32-042stab093.4 #1 SMP Mon Aug 11 18:47:39 MSK 2014 x86_64 x86_64 x86_64 GNU/Linux [root@node16 /]# yum list installed | grep ploop ploop.x86_64 1.12-1 @openvz-utils ploop-lib.x86_64 1.12-1 @openvz-utils [root@node16 /]# lsmod | grep ip nf_conntrack_ipv4 9946 2 nf_nat nf_defrag_ipv4 1531 1 nf_conntrack_ipv4 nf_conntrack 80313 4 vzrst,nf_nat,nf_conntrack_ipv4,vzcpt ip6t_REJECT 4711 0 ip6table_mangle 3669 0 ip6table_filter 3033 0 iptable_mangle 3493 0 iptable_filter 2937 0 xt_multiport 2716 0 ipt_REJECT 2399 0 ip_tables 18119 2 iptable_mangle,iptable_filter ip6_tables 18988 2 ip6table_mangle,ip6table_filter ipv6 322874 3 vzrst,ip6t_REJECT,ip6table_mangle ==== DESTINATION NODE ==== [root@node17 /]# uname -a Linux node17.xxxxx.com 2.6.32-042stab093.4 #1 SMP Mon Aug 11 18:47:39 MSK 2014 x86_64 x86_64 x86_64 GNU/Linux [root@node17 /]# yum list installed | grep ploop ploop.x86_64 1.12-1 @openvz-utils ploop-lib.x86_64 1.12-1 @openvz-utils [root@node17 /]# lsmod | grep ip iptable_nat 6302 0 nf_nat 23213 2 iptable_nat,vzrst nf_conntrack_ipv4 9946 3 iptable_nat,nf_nat nf_defrag_ipv4 1531 1 nf_conntrack_ipv4 nf_conntrack 80313 5 iptable_nat,vzrst,nf_nat,nf_conntrack_ipv4,vzcpt ip6t_REJECT 4711 0 ip6table_mangle 3669 0 ip6table_filter 3033 0 iptable_mangle 3493 0 iptable_filter 2937 0 xt_multiport 2716 0 ipt_REJECT 2399 0 ip_tables 18119 3 iptable_nat,iptable_mangle,iptable_filter ip6_tables 18988 2 ip6table_mangle,ip6table_filter ipv6 322874 3 vzrst,ip6t_REJECT,ip6table_mangle In fact, all the relevant modules are present on the destination node AFAICT. What am I missing here? Thanks, Corrado Fiore _______________________________________________ Users mailing list Users@openvz.org https://lists.openvz.org/mailman/listinfo/users
