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.
DB<1> use Fcntl ':flock'
DB<2> open(FOO, ">>/tmp/gh") or die "darn"
DB<3> flock(FOO, LOCK_EX) || die "SHIE: $!"
DB<4> close FOO
DB<5> open(FOO, ">>gh") or die "darn"
DB<6> flock(FOO, LOCK_EX) || die "SHIE: $!"
SHIE: Function not implemented at (eval
10)[/usr/lib/perl5/5.10.0/perl5db.pl:638] line 2.
DB<7>

Thanks in advance for your assistance.
Regards,
