Hi Funksen,

I tried to do that too but it gives the following error.

Code:
#  mount sapsolman:/commbkp /Shared_BKP_fs
nfsmnthelp: 1831-019 sapsolman: Cannot mount a file system that is already remotely mounted.
mount: 1831-008 giving up on:
sapsolman:/commbkp
Cannot mount a file system that is already remotely mounted.

Regards,
Abhishek.

Hi Cero,

That is correct, agreeing to your point, I too feel that if a file system is not mounted then i cannot umount it, however it is not even mounting
When i have checked in the source server (where the FS exists) the type of FS is
Code:
FS :- sapsolman:/commbkp
Mounted on :- /commbkp
Type of FS :- nfs3

This was checked through SMIT.

Regards
Abhishek

/Shared_BKP_fs is a different mountpoint?


try to remove your fs from /etc/filesystems

(rmfs /filesystemname, or delete it with an editor if that wont work)

and remount it over another path

(save /etc/filesystems or the stanza for your filesystem first)

Hi funksen,

Yes Shared_BKP_fs is a different mount point, originally I was trying to mount at commbkp mount point.

I checked in etc/filesystem no such entry exists for
Code:
'/commbkp'

.

I wont be able to attach the entire output, but as checked by me I was not able to see any entries with the name
Code:
/commbkp


or by the name
Code:
sapsolman:/commbkp

in the filesystems file.

Regards.

strange,

you can try to restart nfs services

Code:
stopsrc -g nfs
startsrc -g nfs

Hi,

Do i need to stop the application and database before executing these commands? also i want to know where can i find all the process id's pertaining to a specific filesystem.

if this is the only nfs mounted filesystem your application is using, and if this server does not share nfs directories itself, then you can run these commands safely

clean way is to see what services are running:

Code:
lssrc -g nfs
Subsystem         Group            PID          Status 
 biod             nfs              2818186      active
 rpc.statd        nfs              6291692      active
 rpc.lockd        nfs              5636344      active
 nfsd             nfs                           inoperative
 rpc.mountd       nfs                           inoperative
 nfsrgyd          nfs                           inoperative
 gssd             nfs                           inoperative


for example

and just restart them
