VDM file systems not listed for NFS exports?

I just finished moving my cif servers from our NS to a VNX.

One the VNX we started using a VDM so I can setup replication back to the NS in our DR data center.

I'm trying to create the same NFS exports we had on the NS which are on file systems shared by the cifs servers, but those file systems are not listed as available to create a NFS export on.

Can I create a NFS export on a file system that is mounted on a VDM?

Thanks,jb

your file system is already mounted, you just need to export it

server_export server_2 -Protocol nfs -option anon=0,access=yourhost,root=yourhost /root_vdm_1/fs_i386

Celerra allow you to mount subdirectories for exampel on your Linux box you would mount like this:

mount VNX:/root_vdm_1/fs_i386/i386  /mnt/local

Yes

Just export from the physical DM and use the full path like /root_vdm_X/... - see server_mount

got it

server_export server_2 -Protocol nfs -name fs_i386 /root_vdm_1/fs_i386

thank you

I tried

server_export server_2 -Protocal nfs -name fs_i386 /root_vdm_1/fs_i386

But it comes back like the command is wrong.

Last night I used EMC Chat support.

They said I had to used server_mount to create the export

But the example they gave me didn't make sense to me.

2)server_mount vdm_01 vdm_01 : charlie_fs_01 on /charlie_mp1 uxfs,perm,rw,accesspolicy=NATIVE charlie_rocp1 on /charlie_rocp1 ckpt,perm,ro,accesspolicy=NATIVE

On my VNX, the vdm is called vdm01 and one of the file systems I need to export is called /fs_i386 but the path needs to be /fs_i386/i386 to export

The file system is already shared via cifs as a shared called i386

When I run server_mount vmd01 |grep fs_i386$  I get

fs_i386 on /fs_i386 uxfs,perm,rw,noprefetch,nonotify,accesspolicy=NATIVE

Dear Sir,

1.How to mount a filesystem (FS) in VDM ( in GUI mode ) for NFS export in VNX storage ?

In GUI, Storage--Storage configuration--Filesystem--create FS. (in that tab have "Select DM Option". Hear, if I previously create a VDM then is it possible to choose a VDM instead of physical DM.)

2.If I create a FS on physical DM and in NFS Export tab can I mount that FS on VDM ?

Santanu,

It can be accomplished via CLI only.

Have a look at the following that will walk you through it:

1) Configuring Virtual Data Movers on VNX

2) Configuring NFS on VNX

3) YouTube Video (as published by EMCCorp)

Hi All,

Need your help please, 

I have created NFS export on a FS mounted on a VDM,

VDM name: vdm01 

File System Name : Test-FS1

server_export vdm01 -Protocol nfs -o root=x.x.x.x,access=x.x.x.x,rw=x.x.x.x /Test-FS1

Then I was able to mount it on my Linux server with the path name /Test-FS1 and I am able to create my files and directories, below is the command


sudo mount -t nfs y.y.y.y:/Test-FS1 vnx003


Where,

y.y.y.y - interface IP assigned to vdm

vnx003 - mount point on server


My Questions,

  1. Is the path name “/Test-FS1” right format or /root_vdm_1/Test-FS1 right way? Reason Please.
  2. Once I create the NFS export through CLI , that NFS export appears on Unisphere
    console for a while and it disappears but still I can see it via CLI,

[nasadmin@CHE-INF-FILE03-CS0 ~]$server_export vdm01 -list

vdm01 :

export "/Test-FS1" root=x.x.x.x access=x.x.x.x rw=x.x.x.x

My question here is, why NFS exports for a vdm is disappearing on GUI after a while?

Thanks

Dino

Because VDM based NFS exports are a CLI only feature - you cannot manage them using the GUI

I think they arent supposed to appear on the GUI

Hi Rainer,

Thanks, yes I understand but I want to make sure the NFS exports for VDM mounted FS won't appear on the GUI.

-------------------------------------------------------------------------------------------------------------------------------------------------------------

So any idea on pathname? my first question.

Because initially when the FS was mounted on physical Data Mover the pathname was /Test-FS1 for File System name Test-FS1 and now I would like to use same pathname after it was moved to VDM, will that work??

Thanks

Dino

i don't see why that would not work, now that you are using VMD, you will specify the same path ..where previously you would have to speicify /root_vmd_x/TESTS-FS1

If you are using VDM exported NFS shares then you need to use that pathname from the VDMs point of view

Just do a “showmount –e VDM_IP” and you will see
