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

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

Vijay,
please find attached test program and log file.
test-code:
$ cat getcwd.c
#include <stdio.h>
#include <unistd.h>
int main(int argc, char* argv[])
{
char cwd[1024];
if ( argc != 2 ) {
printf("usage: %s dir\n", argv[0]);
_exit(1);
}
if ( chdir(argv[1]) != 0 ) {
perror("chdir");
_exit(1);
}
if ( getcwd(cwd, 1024) == NULL ) {
perror("getcwd");
_exit(1);
}
printf("%s\n", getcwd(cwd, 1024));
_exit(0);
}
operations:
~ # ./getcwd /vmfs/volumes/1668aab4-a78e64bd/foo
getcwd: No such file or directory
~ #
Thanks for providing this test program. Can you please provide the output of strace -f ./getcwd /vmfs/volumes/1668aab4-a78e64bd/foo and the corresponding nfs log file?
-Vijay
