While trying to SSH or enter into a VPS from the node, you may get the following error :
Unable to open pty: No such file or directory
or
root@tip~]# vzctl enter 900
enter into VE 900 failed
Unable to open pty: No such file or directory
There is a temporary and permenant fix for this issue.
Temporary Fix :-
Execute the following commands from the node
vzctl exec VEID /sbin/MAKEDEV pty
vzctl exec VEID /sbin/MAKEDEV tty
vzctl enter VEID
Where VEID is the VPS id.
Permanent Fix :-
First temporarly fix the issue and enter into the VPS.
1) vzctl enter VEID
2) Edit the file /etc/rc.sysinit of the VPS
vi /etc/rc.sysini
3) Search for the line /sbin/start_udev and comment it
#/sbin/start_udev
4) Add the following two lines under /sbin/start_udev
#/sbin/start_udev/sbin/MAKEDEV tty/sbin/MAKEDEV pty
5) Reboot the VPS and you are done!
vzctl restart VEID
