I am running CADENCE IC5.0.32 on a linux server SUSE 9.1 and I have a strange problem wiht the cdslmd daemon. Althoug there is no other cdslmd running and no other lock file in /usr/tmp and /var/tmp, cdslmd crashes during start up, asserting that it cannot create the lock file, and that there has to be another cdslmd instance running. I am using lmgrd and cdslmd v8.2.a! So everyone having a clever suggestion about this problem, is welcome .... and I know Cadence only supports RedHat Regards Michael -- Dipl. Ing.

Oh, all right. :-) (Ok, I'll admit it -- at home, I run IC5.x on
Gentoo, but our support folks have to draw the line somewhere with the
n-zillion Linux distros out there.)

I am using lmgrd and cdslmd v8.2.a!

So everyone having a clever suggestion about this problem,

I'd recommend running lmgrd through strace, akin to:

strace -o /tmp/lmgrd.log -f -F \
$CDS_INST_DIR/tools/bin/lmgrd -c /path/to/license.dat

strace options used:
-o spits the output to a file rather than your terminal
-f tells it to follow fork() calls
-F tells it to follow vfork() calls

Then grep the /tmp/lmgrd.log file for open and/or lock calls -- maybe
try a few variations on "grep tmp /tmp/lmgrd.log". I don't recall off
the top of my head, but lock on Linux might show up as ioctl() or
fcntl() calls.

If you need help interpreting the log, gzip or compress it up and send
it to me.

Dear David,

I used strace to start lmgrd and I have attached the log file to his
message.

strace -o /var/tmp/lmgrd.log -f -F /etc/flexlm/lmgrd -c
/etc/flexlm/license.faust02

I am not sure how to interpret the content of the log file. The last
open command that is listed in the log file is the following:

open("/", O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY)

So does cdsmld try to open "/" as the lock file ?
I have read in a linux user group that a root filesystem check is
performed every time the daemon starts. So maybe this open command is
a result of this root filesystem check.

You have to know that my root partition is formated in reiserfs and
not in ext2fs or ext3fs. Someone told me that maybe this is causing
cdslmd to crash. So I formatted an empty and unused partition in ext2
and mounted this partition at /var/tmp and made a soft link to
/usr/tmp. But the problem with the lock file remains. So if cdslmd is
performing a root file system check at startup, maybe cdslmd does not
like that my root partition is formatted in reiserfs and I have to
reformat my whole root partition in ext2?

Regards

Michael

For whatever reason, cdslmd is not even attempting to open the lock file
on your system (the open("/var/tmp/lockcdslmd") entry on my machine).

You have to know that my root partition is formated in reiserfs and

/usr/tmp. But the problem with the lock file remains. So if cdslmd is
performing a root file system check at startup, maybe cdslmd does not
like that my root partition is formatted in reiserfs and I have to
reformat my whole root partition in ext2?

It's possible that reiserfs behaves differently than other filesystems
(the output from my system is actually on an XFS filesystem).
Unfortunately, just putting an ext2 (or other non-Reiser FS) on /var/tmp
isn't going to help -- you will probably need to make another filesystem
and chroot there.

I'll set up a VMware session with ReiserFS and see if I can't replicate
this.

Good thing I found this thread...I was having the same problem Michael
is having . I was in a position to easily reinstall Suse 9.1 so I made
root an ext3 filesystem instead of reiser and now cdslmd starts.
Thanks a mil!

Excellent. I've been having issues getting ReiserFS installed (and
VMware back up after some security updates were applied to my desktop
box), so I haven't had a chance to replicate this. But it sounds like
the culprit has been identified.

I'm surprised that this has an effect on file locking code. It's one of
those things that shouldn't affect correctly-written apps (that is,
we're not going in and explicitly doing "Is this filesystem X? Then do
Y" or "Rely on undocumented features that just happen to work on ext2/3").

For now, I'd just say "Don't do that." :-)

Hello David, I performed a migration of my root file system from reiserfs to ext3 and the deamon is running very well know. Anyone wanting to know how a root file system migration is performed may have a look at the following link: http://www.tldp.org/HOWTO/Linux+XFS-HOWTO/x154.html Michael K.
