Question NFS not showing under /etc/fstab nor /etc/exports
Hi guys, I was asked to perform the following:

On server usdfslpsap04 following NFS mounts should be disabled
Code:
usdfslpwmt3:/u01/opt/wm6_data/ebiz_edi/CALIBER_data
                      50412232  13369544  34481872  28% /u01/opt/wm6_data/ebiz_edi/CALIBER_data
usauxoradw:/DWH/Transfer/current
                     157286400    916096  29728256   3% /Interfaces/DWH/Transfer/current
usauxoradw:/DWH/Transfer/daily
                     157286400  13818688  29728256  32% /DWH/Transfer/daily

I said NO BIG DEAL !!! I will unmount the FS, go to /etc/fstab in the current system and comment out the entry for all these filesystems and algo go to the FS owner system and comment out the same under /etc/exports.

Now,

When I execute utility DF I see the NFS sitting there:
Code:
usauxoradw:/DWH/Transfer/current
                     157286400    936544  29049024   4% /Interfaces/DWH/Transfer/current
usauxoradw:/DWH/Transfer/daily
                     157286400  14421824  29049024  34% /DWH/Transfer/daily

usdfslpwmt3:/u01/opt/wm6_data/ebiz_edi/CALIBER_data
                      50412232  13369544  34481872  28% /u01/opt/wm6_data/ebiz_edi/CALIBER_data

NOW,
In this system check the /etc/fstab file:
Code:
[root@usdfslpsap04 ~]# view /etc/fstab
# This file is edited by fstab-sync - see 'man fstab-sync' for details
LABEL=/                 /                       ext3    defaults        1 1

none                    /dev/shm                tmpfs   defaults,size=44G        0 0

none                    /sys                    sysfs   defaults        0 0
/dev/vg00/lvol2         /tmp                    ext3    defaults        1 2
/dev/vg00/lvol3         /usr                    ext3    defaults        1 2
/dev/vg00/lvol4         /var                    ext3    defaults        1 2

/dev/vg02/lvol0         /oracle                 ext3    defaults        1 2
/dev/vg02/lvol1         /oracle/PV1             ext3    defaults        1 2
/dev/vg02/lvol2         /usr/sap/PV1            ext3    defaults        1 2

## NFS Mounts  ##
usdfslpsap03:/sapmnt/PV1                /sapmnt/PV1             nfs     bg,soft         0 0
#dfuxsdb1:/usr/sap/trans                /usr/sap/trans          nfs     bg,soft         0 0
usdfsldsap03:/software                  /software               nfs     bg,soft         0 0
usdfslpsap02:/Interfaces                /Interfaces             nfs     bg,soft         0 0
usdfslpsap02:/usr/sap/interfaces        /usr/sap/interfaces     nfs     bg,soft         0 0
"/etc/fstab" [readonly] 33L, 2422C

These file systems are not in there. Where da heck they are?

If I go let us say to usdfslpwmt3 and check the /etc/exports I see that the file is empty.

So I guess this are not NFS???

ANy input please !!!!!!!!!!!!!!!!SmilieSmilieSmilieSmilieSmilieSmilie

Code:
[root@usdfslpwmt3 ~]# showmount -e
[root@usdfslpsap04 ~]#showmount -a

But a question first, you have unmounted the file systems and they are still there?
Or is this procedure you are discussing under a restart?
Meaning you umounted (successfully) , deleted entries in /etc/fstab (successfully) , rebooted (successfully) and then you see the filesystems again?
