[one-users] Shell character limitation in ESXi (/bin/sh: File too large)

[Emmanuel Mathot]

Hello,


Using the new attach / detach disk functionality on ONE 3.6, I encountered problems with vmware when the remote scripts /tmp/one/vmm/vmware/attach_disk is executed.

In fact the command is passed to ssh with a very large shell command as this one:

 /tmp/one/vmm/vmware/attach_disk one-432 /var/lib/one/datastores/0/432/disk.2 sdb 1

The shell on ESXi host returns: /bin/sh: File too large
Indeed, once logged on the shell of the host, the command line is limited. The 5th argument is cut.
The script uses only the 4 first arguments and therefore could work without the others but I suppose it is used by other drivers. 
Would you have a workaround or a configuration on vmware that allow more characters in the shell?

Cheers,
