[Lustre-discuss] Problem with flock and perl on Lustre FS

2010-03-05 Thread Jagga Soorma 
Hi Guys,

How does lustre handle locking?  One of our users is complaining that a perl
module (Sotrable) has trouble with its lock_nstore method when it tries to
use flock.  The following is a hwo they are reporducing this issue:

--
 perl -d -e ''

Loading DB routines from perl5db.pl version 1.3
Editor support available.

Enter h or `h h' for help, or `man perldebug' for more help.

Debugged program terminated.  Use q to quit or R to restart,
 use o inhibit_exit to avoid stopping after program termination,
 h q, h R or h o to get additional info.
 DB1 use Fcntl ':flock'

 DB2 open(FOO, /tmp/gh) or die darn

 DB3 flock(FOO, LOCK_EX) || die SHIE: $!

 DB4 close FOO

 DB5 open(FOO, gh) or die darn

 DB6 flock(FOO, LOCK_EX) || die SHIE: $!
SHIE: Function not implemented at (eval
10)[/usr/lib/perl5/5.10.0/perl5db.pl:638] line 2.

 DB7

Thanks in advance for your assistance.

Regards,
-J

Search the list or manual for -o flock, -o localflock, and -o  
noflock mount options for the client(s).

Cheers, Andreas
