Client does not start after migration

[stony999]

I set up a Proxmox Cluster with 2 nodes and ProxMox 1.6-5261-4. In order to move the machines to another location, I migrated my 2 clients from Master to the second Node.
After Migration 1 client started, the other one seems as if it would start, but in fact it is not reachable.
On the Web GUI it shows:

Status:    running    
Hostname:    fax2.mydomain.de    Uptime: 00:09:45
IP Adresse:    192.168.178.211    Öffne VNC Konsole

Festplattenplatz (GB):    2.63      8.00    32.88%

It stays at 1 MB memory and does not change.

Cmdline with --force does not change anything:

proxmox:/var/log# vzctl start 104 --force

Log file shows nothing special

Where can I search for the problem?

Edit: The client already ran on this machine previously, also the hardware of both machines is almost identical.

Edit:
Dies this mean anything?

Hi,
i don't think that's resolv your problem. But to fix run

dpkg-reconfigure locales

and select de_DE.UTF-8 for german.

Is there any hint in the init log?

 

[stony999]

After a while I get

proxmox2:/var/lib/vz/private/104/var/log# cat init.log
starting init logger
mountall: root filesystem isn't mounted
init: mountall main process (30) terminated with status 1

init: mountall main process (30) terminated with status 1

Seems your init scripts does not detect that the root is already mounted by openvz. So you need to modify your init scripts. Did that ever worked?

 

[stony999]

As I stated, the client already ran on this machine previously. This started to happen after a migration.

Btw: I had some problems with an NFS share previously which the client also tried to mount (according to mtab). This lead to the delayed output of init.log.
But since then I have unmountet the NFS and the client thus doesn't start.

As I stated, the client already ran on this machine previously.

'running' and 'starting' is something different. Maybe you did an update inside the container?

 

[stony999]

I migrated it from server 1 to server 2. It worked on Server2.
So there was not update in the container.

I migrated it back to server 1. It failed.
I tried to migrate it to server 2. It failed again.

Here is also the output of mtab in the container

Is there something wrong?

 

[stony999]

I installed another client from an openvz Ubuntu 10.04 template. So now I have two running and one failed clients

• 102 is running (Proxmox Debian 6.0 Standard)
• 104 has failed (openvz Ubuntu 10.04 amd64)
• 106 is running (openvz Ubuntu 10.04 amd64)

I compared the mtab entries on the machines:

/var/lib/vz/private/102 /var/lib/vz/root/102 simfs rw,relatime 0 0
/var/lib/vz/private/104 /var/lib/vz/root/104 simfs rw,relatime 0 0
/var/lib/vz/private/106 /var/lib/vz/root/106 simfs rw,relatime 0 0

A similar entry for each machine

none /var/lib/vz/root/102/proc proc rw,nosuid,noexec,nodiratime,relatime 0 0
proc /var/lib/vz/root/104/proc proc rw,relatime 0 0
proc /var/lib/vz/root/106/proc proc rw,relatime 0 0

A similar entry for each machine

none /var/lib/vz/root/102/sys sysfs rw,relatime 0 0
sysfs /var/lib/vz/root/104/sys sysfs rw,relatime 0 0
sysfs /var/lib/vz/root/106/sys sysfs rw,relatime 0 0

A similar entry for each machine

none /var/lib/vz/root/102/lib/init/rw tmpfs rw,nosuid,relatime,size=262144k,nr_inodes=65536 0 0
none /var/lib/vz/root/102/dev/shm tmpfs rw,nosuid,nodev,relatime,size=262144k,nr_inodes=65536 0 0

Entries only for Debian machine. But Ubuntu 106 is running so there should not be a problem.

none /var/lib/vz/root/102/dev/pts devpts rw,nosuid,noexec,relatime,mode=600 0 0
none /var/lib/vz/root/106/dev/pts devpts rw,relatime,mode=600 0 0

Entries only all machines except for the failed one. So here we may see the problem.

How can I solve this missing devpts entry?
Also the contents of
/var/lib/vz/private/<id>/lib/udev/devices
on both Ubuntu clients are the same


Or is /dev/pts being mounted after "/" ?
