Re: Cannot run VMware Virtual Machines on GlusterFS

Tomoaki,

 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?

Avati,

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

Yes, I am.

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].

please find attached.

Regards,

Tomo

   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

           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
