NFS Mounting of the Server

Dear all,
I want to mount one folder from the remote server to the local. I shared the folder in the remote server but I am unable to see the shared folder with dfshares command neither from local server nor from remote server as dfshare pegas (remote server name)
I am getting following error while trying to execute the command.
# dfshares
nfs dfshares:pegasusnode1: RPC: Rpcbind failure - RPC: Timed out
dfshares pega
nfs dfshares:pega: RPC: Rpcbind failure - RPC: Unable to receive
Please help.
Thanks in advance,
Bikash

If the server had no shares before, it's likely that the nfs server daemons have not been started.
After populating /etc/dfs/dfstab, start the nfs/server service.

Adaptiv Computing Controller / do i need NFS Mounts for Application Server?

Hello,
i got a question about the Adaptiv Computing Controller.
Do i need NFS Mounts for the Application servers?
Or can i handle this from the SAN too?
Can anybody help me here?
Thanks

ATA bus error means that data corruption occurred during transmission over ATA bus (SATA or PATA). This type of errors can be indicated by
ICRC or ABRT error as described in the section called “ATA/ATAPI device error (non-NCQ / non-CHECK CONDITION)”.
Controller-specific error completion with error information indicating transmission error.
On some controllers, command timeout. In this case, there may be a mechanism to determine that the timeout is due to transmission error.
Unknown/random errors, timeouts and all sorts of weirdities.
As described above, transmission errors can cause wide variety of symptoms ranging from device ICRC error to random device lockup, and, for many cases, there is no way to tell if an error condition is due to transmission error or not; therefore, it's necessary to employ some kind of heuristic when dealing with errors and timeouts. For example, encountering repetitive ABRT errors for known supported command is likely to indicate ATA bus error.
Once it's determined that ATA bus errors have possibly occurred, lowering ATA bus transmission speed is one of actions which may alleviate the problem.
I'd also add; make sure you have good backups when ATA errors are frequent

Can you re-export an nfs mount as an nfs share

If so what is the downside?
I'm asking because we currently have an iscsi san and a recent upgrade
severely degraded iscsi connectivity. consequently can't mount my iscsi
volumes.
Thanks,

Thank you,

Depending on which Novell OS you are running.... this subform is for NetWare, but I suspect you are using OES Linux.
I've never tried creating a NCP share on OES for a remote NFS mount on the server. My first guess would be it is not allowed and also not a good practice. You could however, with this situation and if you are running an OES2 or OES 11 Linux server, try configuring an NFS mount on the OES server and then configuring the NCP share on that using remote manager on the server.
What I would recommend however to see if the iSCSI issue cannot be fixed or worked around.
Could you describe a bit more of the situation there/what happened and what is not working on that end?

Cannot write to NFS mount with finder

hi folks
i have moved from a G4 cube running 10.4.9 to a new iMac running os x 10.5.7 (including upgrading from the old machine)
the NFS mounts i used to have with my G4 cube are not working properly; new mounts i've created aren't working properly either.
i can read/open file OK, but when i try to drag & drop files onto the NFS mount using the finder i get errors:
"You may need to enter the name and password for an administrator on this computer to change the item named test.jpg" [ stop ] [ continue ]
clicking "continue" i get:
"The item test.jpg contains one or more items you do not have permission to read. Do you want to copy the items you are allowed to read? [ stop ] [ continue ]
Choosing continue again results in the file appearing in the NFS directory, but with 0 size, and a time stamp of 1970.
if i try to copy the same file using the Terminal, it works fine - so it is not a simple NFS permissions problem - it is something particular to the Finder.
i am able to create a folder inside the NFS director by using the Finder.
i thought at first it might be related to the .DS_Store and similar files being written, so i tried turning off that behaviour:
defaults write com.apple.desktopservices DSDontWriteNetworkStores true
but that hasn't fixed the problem
there are no obvious messages in any of the logs
any suggestions or pointers on how to fix this?

thanks for the reply
these articles appear to relate to sharing a mac filesystem via NFS: exporting the data.
i am referring to mounting a NFS filesystem from another server onto the mac (leopard) client
the mounting works fine: it's just the finder which isn't behaving. the finder worked in tiger; isn't in leopard.

TM ignores NFS mounted user

BS"D
There has been a lot of discussion about using NFS mounts as targets for TM; I have the opposite problem: I want TM to back up a user whose home directory resides on an NFS server. The user's home directory is in /Users, as a link to the mount point of the NFS volume in /Volumes/.....
TM backs up the system disks, but does not follow the link to the users directory.
Any ideas?
Thanks

I don't think TM supports network mounted disk volumes. You should probably submit feedback to Apple and ask that this feature be supported. You're also might be better off backing up that nfs volume from the server that hosts it.

Need to know how to calculate and allocate the server side bandwidth between two exchange sites for DAG replication

Hi All,
Please have a look in to the below mentioned environment.
primary site :SITE 1
server 1
server 2
secondary site :SITE 2
server 3
Note : All the above three servers are in single DAG .All the database are mounted on the server (server 1) which is located in the primary site (I.E SITE 1).
On that 5 databases we are having 3500 users .Based on the user designation we have allocated the mailbox size.
Query : Each and every day we are having the large no copy queue length for all the five databases to the server located in SITE 2.
Please help me out on this and also tell me is there any tool available to exactly get the required bandwidth for the exchange servers located between the active directory sites.
Thanks & Regards S.Nithyanandham

I don't know of any tool that can calculate things for you but latency is the biggest thing you have to worry about. The other issues is looking at the network gear between the 2 sites. I have seen many times were switches get maxed out if they are set to
1 GB or even ports getting maxed out and need to bonded for more throughput. Test your latency from the edge of each site then test it within to see if there is a difference.
Regardless of their geographic location relative to other DAG members, each member of the DAG must have round trip network latency no greater than 500 milliseconds between each other member.
As the round trip latency between two Mailbox servers hosting copies of a database increases, the potential for replication not being up to date also increases. Regardless of the latency of the solution, customers should validate that the networks between
all DAG members is capable of satisfying the data protection and availability goals of the deployment. Configurations with higher latency values may require special tuning of DAG, replication, and network parameters, such as increasing the number of databases
or decreasing the number of mailboxes per database, to achieve the desired goals.
Round trip latency requirements may not be the most stringent network bandwidth and latency requirement for a multi-datacenter configuration. You must evaluate the total network load, which
includes client access, Active Directory, transport, continuous replication, and other application traffic, to determine the necessary network requirements for your environment.

NFS mount from multi-homed server over TCP fails

nico: Solaris 9 NFS server, multihomed into three different networks (A, B, C)
primary interface on A.
benno: Solaris 10, NFS client, on network
genie: RHEL5, NFS client, on network B
ilsco: Solaris 10, NFS client, on network B
I have immediate access to all servers except ilsco -- which, of course, is the one with the problem. =( If genie tries to mount a share from nico using its address on network A, everything works. If it tries to mount it using the address on network B, it fails.
In all cases, I can see the client make request to the server's portmapper daemon for the mountd port number. That request is issued to nico's address in network B. Nico replies, from its primary address in network A. When NFS works, I then see a null mount request issued by the client. Genie never issues that mount request.
Working request from benno:
[CLIENT] -> [SERVER, ADDR B] PORTMAP C GETPORT prog=100005 (MOUNT) vers=3 proto=UDP
[SERVER, ADDR A] -> [CLIENT] PORTMAP R GETPORT port=58352
[CLIENT] -> [SERVER, ADDR B] MOUNT3 C Null
[SERVER, ADDR A] -> [CLIENT] MOUNT3 R Null Non-working request from ilsco:

[CLIENT] -> [SERVER, ADDR B] PORTMAP C GETPORT prog=100005 (MOUNT) vers=3 proto=UDP (retransmit)
[SERVER, ADDR A] -> [CLIENT] PORTMAP R GETPORT port=32804Now, I've noted that, despite using the "-o proto=tcp" option, the portmap requests were pushed out over UDP. On benno, some of the traffic after the portmap request took place on the network A address; some of the traffic took place on the network B address.
On genie (the Linux box), I noted that the portmap requests were pushed out over the TCP and all traffic stays on the network B addresses.
Any suggestions, etc. as to what I am doing wrong or what else I should be looking at would be helpful.

Turned out it might just be a firewall issue... I didn't think about it first :(
Sorry for that :x

Windows server 2008 R2 and NFS mounted subdirectories.

I am mounting from a Windows Server 2008 R2 Box to a RHEL 6.3 machine and I am able see the folders; however, I am unable to see the sub-folders via the mapped NFS mount in windows. Any ideas as to why? Some additional facts are below.
1. We are using an NFS mount from Windows to RHEL (mount -o
\\RHELBOX\ops\resources R:) We NFS mount from RHEL to a Storage device - the fstab entry looks like this:
10.9.9.9:/vol/afpres1/psf_prod
/ops/resources/prod     nfs
_netdev,defaults
0 0
10.9.9.9:/vol/afpres1/psf_test
/ops/resources/test       nfs
_netdev,defaults
0 0
10.9.9.9:/vol/afpres1/baselib
/ops/resources/psf
nfs          _netdev,defaults
0 0
The RHEL export file looks like this.
/ops/resources 10.4.4.4(rw,sync,no_all_squash,insecure,nohide) (the 10.4.4.4 IP address is the of the 2008 r2 server
/ops/resources 10.4.4.5(rw,sync,no_all_squash,insecure,nohide)
/ops 10.4.11.66(rw,sync,no_all_squash,insecure,nohide)
#/ops/resources *(rw,sync,no_all_squash,insecure,nohide)
/opspool *(rw,sync)

"Network Error - 53" while trying to mount NFS share in Windows Server 2008 client

CentOS | Windows 2008
I've got a CentOS 5.5 server running nfsd. On the Windows side, I'm running Windows Server 2008 R2 Enterprise. I have the "Files Services" server role enabled and both Client for NFS and Server for NFS are on.
I'm able to successfully connect/mount to the CentOS NFS share from other linux systems but am experiencing errors connecting to it from Windows. When I try to connect, I get the following:
C:\Users\fooadmin>mount -o anon 10.10.10.10:/share/ z:
Network Error - 53
Type 'NET HELPMSG 53' for more information.
(IP and share name have been changed to protect the innocent :-) )
Additional information:
I've verified low-level network connectivity between the Windows client and the NFS server with telnet (to the NFS on TCP/2049) so I know the port is open. I've further confirmed that inbound and outbound firewall ports are present and enabled.
I came across a
Microsoft tech note that suggested changing the "Provider Order" so "NFS Network" is above other items like Microsoft Windows Network. I changed this and restarted the NFS client - no luck.
I've confirmed that the share folder on the NFS server is readable/writable by all (777)
I've tried other variations of the mount command like: mount 10.10.10.10:/share/ z: and
mount 10.10.10.10:/share z: and mount -o anon mtype=hard \\10.10.10.10:/share * No luck.
As per the command output, I tried typing NET HELPMSG 53 but that doesn't tell me much. Just "The network path was not found".
I'm lost on how to proceed with troubleshooting. Any ideas?

There are usully two aspect that come to mind:
1. Syntax of mount command
2. Mismatch of NFS versions
Third reason is here

OEL 6.3 - mount.nfs: access denied by server

Hi,
I am trying to mount an NFS directory on a server running OEL 6.3, pointing to another OEL 6.3 server. I get the following error:
[oracle@csdowmsdb503 etc]$ mount 192.x.x.x:/home/oracle/m501/m501_f /home/oracle/m501_f/
mount.nfs: access denied by server while mounting 192.x.x.x:/home/oracle/m501/m501_f
The UIDs and GIDs on each server match. If we use "nfsvers=3" it work, so it seems to be something specific to vers 4. We would like to not use the vers 3 workaround.
Thanks!

Hi,
When I added "- v" I realized it is actually erroring out on vers=4 and defaulting to vers=3 instead. The error it shows is now "No such file or directory."

Temporary NFS mount keep being mounted while server is powered off

I was doing some performance testing using different file protocols (NFS, SMB mainly).
The last test was with NFS, I mounted on the command line the nfs exported directory, did my test, forgot about the moment and shutdown the NFS server. Since then OS X is bugging me every 2 minutes with a popup (which has the focus!) which states "There was a problem connecting to the server 192.168.1.250". The mount is not visible via 'df' so I decided to reboot the machine... But even after rebooting it, the popup keep on poping up!
The setup was: OS X 10.8 as NFS client; FreeBSD 9.1 as NFS server (in a virtual machine hosted by a Linux machine on the same network). The command was:
mount -t nfs 192.168.1.250:/mnt/test ~/mnt/
I restarted the FreeBSD VM, suddenly the NFS export was mounted, this time as /Volumes/test. I unmounted it this time using:
sudo umount /Volumes/test
It did work successfully. I shutdown and deleted my VM, and some hours later the popup reappeared!!
How to get rid of it? Or more explicitely where is the configuration file where the mount is still explicitely present?
(it is not in /etc/fstab, nor /etc/auto_master) I did a huge grep using the IP address on the disk, and I got only log errors in /var/log.

This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then either copy or drag it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click the line of text below to select it:
kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}'
Copy (command-C) the selected text to the Clipboard. Then click anywhere in the Terminal window and paste (command-V). Post the lines of output (if any) that appear below what you just entered. You can do that by copy-and-paste as well. Omit the final line ending in “$”. No typing is involved in this step.
Step 2
Repeat with this line:
sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix)|edu\.mit|org\.(amavis|apache|cups|isc|ntp|postfix|x)/{print $3}'
This time you'll be prompted for your login password, which you do have to type. It won't be displayed when you type it. Type it carefully and then press return. You may get a one-time warning not to screw up. You don't need to post the warning. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.

Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output.
You can then quit Terminal.

The stavfs() hangs for stale NFS mount

Hi,
When the remote server from where a NFS file system is mounted is down, we get the stale NFS
mount error.
An application that just reads the entries of /etc/mnttab and does the statvfs() on all the file systems will
hang infinitely. The control is within the statvfs() call. The application goes into a uninterruptible sleep mode. Signals like SIGALARM or SIGPIPE are not handled. Only the signals like SIGTERM, SIGHUP,
SIGKILL are getting handled.
One solution which we considered was to check for the availability of the remote host before calling the
statvfs(). This can be done by sending ICMP packets to the remote host. But this method will not work
on the servers which restricts the ICMP packets (for some security reasons).
Is there any other way to avoid this problem?
Thanks in advance.
Best Regards,
Rams.

And again. Since 280 people have looked at my post and not one could help me I assume that there's no solution to my problem?
If that's true I would appreciate it if you tell me, and if there's a solution you know, or if you have any idea how to solve this, please reply.

LDAP and NFS mounts/setup OSX Lion iMac with Mac Mini Lion Server

Hello all,
I have a local account on my iMac (Lion), and I also have a Mac Mini (Lion Server) and I want to use LDAP and NFS to mount the /Users directory, but am having trouble.
We have a comination of Linux (Ubuntu), Windows 7 and Macs on this network using LDAP and NFS, except the windows computers.
We have created users in workgroup management on the server, and we have it working on a few Macs already, but I wasnt there to see that process.
Is there a way to keep my local account separate, and still have NFS access to /Users on the server and LDAP for authentification?
Thanks,
-Matt

It would make a great server. Bonus over Apple TV for example is that you have access via both wired ethernet and wireless. Plus if you load tools from XBMC, Firecore and others you have a significant media server. Cost is right too.
Many people are doing this - google mac mini media server or other for more info.
Total downside to any windows based system - dealing with constant anti-virus, major security hassels, lack of true media integration and PITA to update, etc.
You should be aware that Lion Server is not ready for prime time - it stil has significant issues if you are migrating from SNL 10.6.8. If you buy an apple fresh Lion Server mac mini you should have no problems.
You'll probably be pleased.

Cannot mount NFS shares using the Finder

Hello all!
I have a directory structure on a OpenSuse NFS Server which I like to browse/read using my MAC OSX 10.5.6. It works like a joy when I am mounting the NFS share on the command line using "sudo":
sudo mount -o resvport nfshost:/full/path/NFS/share /My/mount/point
However, this is kind of unconvenient as I need to start Terminal and sudo always asks me for the root password. I would appreciate to mount the NFS share just as I mount afp shares using the Finder. But the NFS share is neither searchable using the Finder nor does it show up in the list of host in the side bar of the Finder.
Does anyone has an idea how to solve that? Thx for your information!

The problem is most likely that your NFS server requires that connections come from reserved ports but you can't connect that way from the Finder GUI.
Your example:
sudo mount -o resvport nfshost:/full/path/NFS/share /My/mount/point
shows that you need to use "-o resvport" and that you need to do the mount as root. (This is because the networking stack requires you to be root to get a reserved port.) When you try to mount it via the Finder, you can't specify any mount options like "-o resvport" and even if you could the mount would fail because the Finder isn't running as root.
My first suggestion would be to change the configuration of your server to not require clients to use reserved ports for the NFS protocol. Unfortunately, Linux chooses to call that option "insecure" even though requiring the use of reserved ports (using "secure") doesn't actually make NFS more secure.
Alternatively, you could configure the mount to be performed by something that does do the mount as root - e.g. automount/autofs. You can do this by configuring the mount on Directory Utility's "Mounts" section... you'll want to add "resvport" to the "Advanced mount options" field.
