https://myhost-ip:8006 web gui does NOT respond

[pyhta4og]

1. Installed proxmox 3.0. Everything worked
2. moved /var to another lvm:
/mymount->/vg0/var
cp /var/* /mymount
vi /etc/fstab ... changed mounting of /var to /vg0/var
reboot

3. now all files from /var are in new /var. But while restarting proxmox could write some new stuff there. Or some locks. or some weird things got unsynchronized as the result
5. after reboot web-gui does not work. It is connected to 8006 and nothing is received.

Please advice how can I troubleshoot it? Are there any relevant logs?

Thank you very much.

here are some commands I tried:
