Make sure that you have /dev/ptmx on your servers:

# ls -la /dev/ptmx
ls: cannot access /dev/ptmx: No such file or directory

Create it if necessary:

# mknod --mode=666 /dev/ptmx c 5 2

and repeat migration with rsync again.

Re

IgorG,

/dev/ptmx already exist as you can see:

# ls -la /dev/ptmx
crw-rw-rw- 1 root tty 5, 2 4 juin 16:02 /dev/ptmx

 

[IgorG]

On both servers?

 

[Mickael Salfati]

Yes:

ls -la /dev/ptmx
crw-rw-rw- 1 root tty 5, 2 jun 14 08:52 /dev/ptmx

I have the same problem,do tou get to resolve this problem?
I try to do migartion between two serves with plesk 10.4

 

[Mickael Salfati]

Nope, just disable Rsync protocol and everything will be fine.

This error can occur if /tmp fills up since even when using rsync to migrate, Plesk stupidly doesn't check how large /tmp is before deciding to extract tar files there; such as database dumps. You may need to temporarily unmount /tmp and use the root filesystem to give it enough space to complete.
