spool dir cdsl?

[Michael Schulte zur Sur]

Hi everybody,

should a spool dir on a stand alone system with Tru Unix 5.1A be a cdsl or does it not matter?

greeting,

Michael

Hello,

Could you clarify ?

In your case, what is the specified directory ?

Thanks,

Hi,

you have /usr/spool/lpd as cdfs and /usr/spool/lpd0 as directory.
On a cluster it must be a cdfs, but on a single system? Is there any recommendation?

thanks for your time,

Michael

Hello,

Have a look to OSFPRINT520 inventory file :

/usr/.smdb./OSFPRINT520.inv:0 35 00000 0 0 120777 8/1/01 520 s ./usr/var/spool/lpd ../cluster/members/{memb}/spool/lpd OSFPRINT520

So /usr/var/spool/lpd or
/usr/spool/lpd

#ls -ldi /usr/spool/lpd
991 lrwxrwxrwx 1 root system 35 Nov 20 2002 /usr/spool/lpd -> ../cluster/members/{memb}/spool/lpd

#ls -ldi /usr/var/spool/lpd
991 lrwxrwxrwx 1 root system 35 Nov 20 2002 /usr/var/spool/lpd -> ../cluster/members/{memb}/spool/lpd


=>should be a cdsl.

#ls -l /usr/spool/lpd/
total 1
-rw-r--r-- 1 root system 7 Oct 28 17:24 lpd.lock


And the following printer spool dirs as directories:

#ls -ld /usr/spool/lpd?
drwxr-xr-x 2 daemon daemon 8192 Apr 30 2003 /usr/spool/lpd0
drwxr-xr-x 2 daemon daemon 8192 Jul 8 11:03 /usr/spool/lpd1
drwxr-xr-x 2 daemon daemon 8192 Nov 4 17:28 /usr/spool/lpd2

Then on a standalone machine
# hwmgr -view cluster
hwmgr: This system is not a member of a cluster.
# sizer -v

It's similar,
# grep spool/lpd /usr/.smdb./*.inv
/usr/.smdb./OSFPRINT520.inv:0 8192 00000 0 0 040755 8/1/01 520 d ./usr/var/cluster/members/member0/spool/lpd none OSFPRINT520
/usr/.smdb./OSFPRINT520.inv:0 35 00000 0 0 120777 8/1/01 520 s ./usr/var/spool/lpd ../cluster/members/{memb}/spool/lpd OSFPRINT520

Should also be a cdsl.

Hope it helps,

Hi,

why is your lpd a cdsl and lpd0 a plain directory? They are both spool directories!?
That´s my question. Should a spool directory be a cdsl or not, od does it not matter?

Hello,

The /usr/spool/lpd/ cdsl contains a file lpd.lock.

In this file lock file, you can notice that a PID value is present. This PID refers to lpd daemon.

In a cluster, of course these PID values are different so it also explains why a cdsl.
Should be a cdsl.

In fact on a stand alone system, with a "lpd" directory probably it could work as in V4.X releases but you could encounter some trouble during patch ou upgrade installations.

$ pwd
/var/cluster/members/member1/spool/lpd
$ ls
lpd.lock
$ cat lpd.lock
525313
$ ps -ef | grep 525313
root 525313 524289 0.0 Oct 28 ?? 0:00.01 /usr/lbin/lpd
tino 627333 627307 0.0 09:04:37 pts/1 0:00.00 grep 525313
$ ps -ef | grep 525313 | grep -v grep
root 525313 524289 0.0 Oct 28 ?? 0:00.01 /usr/lbin/lpd
$
The lpd? spool should be directories.

Hi,

so far, I have made then all cdsls. It should not hurt. I will create one printer with lprsetup and see, what it does. Unless there are more serious concerns with this, I would call this case closed.

thanks for your assistance,

Michael

Hi,

I have redone them all and they are plain directories now.

[Dave Bechtold · Accepted solution]

Hi Michael,

In a default installation for a standalone system the /var/spool/lpd directory is a CDSL (Context Dependent Symbolic Link). Even though the system is not in a TruCluster configuration we still define all the base OS CDSL's. You can check the integrity of any systems CDSLs, Clustered or not, by executing /usr/sbin/cdslinvchk .

The defined printers spool directory, i.e. /var/spool/lpd1 for printer lpd1, will _not_ be a CDSL by default. This allows other members in a TruCluster environment to process any printers spool directory regardless of where the job is submitted. If HOST1 is already processing /var/spool/lpd1 spool directory and HOST2 comes along and drops a job in that spool area, then HOST1 will process the job. There is a printcap flag "on=" to restrict/order which TruClusters members process a printers spool area.

Having /var/spool/lpd as a non-CDSL directory on a standalone system would not be a standard setup.

Hope this helps,
Dave Bechtold

Hi Dave,

thats a precise and clear answer, which gives me the rest of information I needed.

thanks,

Michael
