Re: [Gluster-devel] Cannot run VMware Virtual Machines on GlusterFS

I've tried 'getcwd' on the ESXi host with both the Linux kernel NFS server and 
the GlusterFS(NFS) as I saw following message in the vmware.log.

 vmx| FILE: File_Cwd: getcwd() failed: No such file or directory
 vmx| Unable to determine absolute path for '.'.
 vmx| Msg_Post: Error
 vmx| [msg.filePosix.getcwd] Unable to retrieve the current working directory: 
No such file or directory. Check if the directory has been deleted or unmounted.
 vmx| [msg.monitorLoop.createVMFailed] Failed to power on 
VM----------------------------------------

The Linux kernel NFS server serves an Ext3 on a local disk.
The VMkernel does not fail at getcwd with the Linux kernel NFS server and does 
fail at getcwd with the GlusterFS(NFS) in my environment.
