Tomoaki,<div> What is /baz/ which is prefixed behind foo as /baz/foo in the logs, but does not show up in your ls -lR? Can you also send me ls -liR so that I can match inode numbers from the trace?</div><div><br></div><div>

I saw your log and there is nothing suspicious in it. Are you sure the log captures the event where 'getcwd' returned a failure?<br>

Can you also return the output of 'ls -lR of the data set' (from a dir level above) along with the getcwd and capture trace nfs logs from the full session? [and keep the trace nfs logs restricted to just these commands].<br>

please find attached.<br>

Thank you for your attention to this matter.<br>
<br>
I could not find strace command on the ESXi hosts.<br>
CentOS version of strace command says "strace+ ptrace(PTRACE_TRACEME, ...): Function not implemented" on the ESXi host.<br>
<br>
Please find attached log file.<br>
This log file is smaller than the previous version and covers only the 'getcwd' period.<br>
<br>
Regards,<br>
