File path limitation across lan shared storage

Friends,
I realize that the mac os does not have a file path limitation and a file name limit of 255 char.
But, Is there a path length limitation specific to adobe products ( in order to make projects more cross platform ).
I have adobe InDesign and have projects (files) on a NAS I am experiencing difficulties with the files on the nas.
[ crashing the app , running slow ] I am wondering if having files nested 10 -14 levels deep could be a problem.
My file path length are about 80 - 200 char.
the nas is a buffalo terrastation [ xfs ] attached 1000 mbps
thanks

Service that run Application Server specifies in Log
On Tab, Log on as Local System account.
And when I run the servlet through its url, user.name
JAVA property is SYSTEM.
When I log on to the server with Admin user and invoke
the servlet's doGet method from other java class
locally, writing is succeeded. user.name JAVA property
in this case (when I logged on) is Admin.
Probably I should be logged on to the system before I
can perform operations with files on the local
network?So Admin has permission to write to that share but 'Local System' doesn't.
Option 1 (recommended): Check out jCifs, if you use that you can specify a different user to write to the share from that which the system is running under.
Option 2: run the service as a user who does have appropriate permissions.
Option 3: run the application server in the foreground instead of as a service.

File path of open data storage

Hello all!
Now I'm using the blocks of open data storage, write data and close data storage for storing and extracting result data. For the file path issue, before I
set the data path by double clicking the "open data storage" block and inserting the file location in the indicated place, and that worked!
Now since I made a stand alone application of this program and shall use it in other computers, the file location I inserted in open data storage block isn't
valid any more in other PCs. So I modified my source code by connecting a "current vi path" to the open data storage block's file path node instead of
inserting it inside the block, and this doesn't work! During running there shows an error in the write data block saying that the storage refnum isn't valid!
I'm wondering why I couldn't specify the file path like this. Any way to allow me to specify the file path as the current vi path?
Thanks!
Chao
Solved!

You need to account for the path changes when built in to an application, have a look at this example.

LAN Setup - File path for WritExtFile function

Hello:
I am currently using the WriteExtFile function and am
wondering if I need to access a file located on another computer am
I able to use this function. e.g. is there a proper file path that
I can enter into the first parameter of the WriteExtFile to
recogonize a data file located another a networked computer? The
computer will be using windows XP. Any help would be
appreciated.

Yes, you should be able to use WriteExtFile to a networked
location. The
way I've done it in the past is to share a folder on the
other computer on
the network, then map that shared folder as a drive on the
first machine.
Then the path is that drivename^":\\"^RestOfPath...however
you want to set
it up.
There is some admin that has to take place on the networked
machines - to
wit: sharing the write location and mapping the shared
folder. You have to
be careful about permissions and accounts when using XP,
also. Be sure that
the admin that sets up the share leaves it open to all the
potential
machines and user accounts that are likely to want to write
to the shared
location.
Let me know if I can provide more details. Also check the
search criterion
'LAN' or something similar on the AWARE list archines.

In the old Mobile me storage I had shared storage for my family and all of our devices. How do I breakup the 55GB across my apple accounts now that iCloud is by device by user?

In the old Mobile me storage I had shared storage for my family and all of our devices. How do I breakup the 55GB across my apple accounts now that iCloud is by device by user? Anyone else have this issue. I am also in need of correcting the storage from my work where I do not have Safari or I can not down load iCould to my desk top.

That storage moves to master account. Since there are no accounts like that in Icloud, people in your family will enjoy complimentary 5 gigs from Apple and they will let you know if they need anymore. You will not be able to manage storage from windows desktop

NAS Problems! Maxtor Shared Storage II not accepting long file names

Somebody help me!!!! Maxtor Shared Storage II. can't accept beyond certain filename length. And Maxtor says its Mac compatible. What a bull! Now, is there a way for me to do it via ethernet? Or do I have to use a usb cable with matching ends? And once I've reformat it, will everything works just as fine as well? I mean all the capability of the RAID and network?
Cheers!

Thanks for the technical jargon thingy – the hatter – I've been spending the couple of my sleepless hours finding out about the problem that I have came across that FAT32 thingy numerous times.
Next month I'll be turning 32. Lucky for me, I'm not FAT and make sure I won't otherwise I start becoming 'Mac-unfriendly' even though I'm definitely am very compatible.

File Copied to Maxtor Shared Storage NAS Drive Disappearing?

I attached a new Maxtor Shared Storage II (500 Gb) drive to our wireless router, and have discovered problem with disappearing files when trying to copy a local file to a folder in the NAS drive.
Open a window to an empty folder on the NAS drive. Drag a file on the desktop of the local machine to the folder. File appears to be successfully copied.
However, looking at the info bar of the target window immediately after the copying operation shows that the folder contains TWO files (even though only one is shown in the window). After a few seconds, the file disappears and the window shows 0 files. There is no error message.
The desktop file I'm trying to copy has an image icon (as with many files in Leopard). However, the file in the NAS folder window always shows a generic Preview icon during its brief existence.
This happens about 75% of the time.
Occasionally, the window does show two files after copying, and both files will disappear. When this happens, one of the files has a generic Preview icon, and the other has an Acrobat icon.
Other times, the drag and drop produces no files on the target window and no error message.
The file that shows the problems is this file: http://www.businesslink.gov.uk/Promotionsfiles/businesslinkgovukrun.pdf
I'm running Leopard 10.5.1, everything up to date. Can anyone shed light on this problem?
What seems to me to be happening is that when Leopard copies a file with an image icon, it copies the icon separately from the file. After the copy, it ties them up together. If something is not quite right, it can't "bundle" the icon with the file, and the copy operation falls down.

This seems to me related to this problem
http://discussions.apple.com/thread.jspa?threadID=795814&tstart=30
I think it's the mixture of wired and wireless in combination with certain routers.

Access iphoto 08 file on shared storage device from multiple machines

I recently installed ilife 08 on both an imac and macbook. Previously (iphoto 06), both devices accessed the iphoto library on a shared storage device without any problems. After the upgrade, my imac is able to view thelibrary but my macbook (the second machine to be upgraded) no longer has access. 'Sharing' is too slow over the wireless network and doesn't represent a reasonable option.
Is anyone else experiencing this issue? Any suggestions.

Actually, neither repairing permissions or changing them with Get Info worked for me. What did work for me was deleting the empty iPhoto Library in the user folder who couldn't access the shared library, and put an alias of the shared library in that user's Pictures folder. Everything then worked as it did prior to upgrading. Thanks.

How do i move files from ipad to shared storage, how do i move files from ipad to shared storage

I have run out of room on my 64GB iPad. It contains two series of a TV program and I want to keep the episodes. However I would like to be able to get at these episodes wherever I am located be it in Australia, Europe or the USA so would like to have them located in shared storage. What is the best way to achieve this. I am somewhat confused with my choices and my last update experience of losing a number of movies makes me nervous. Any suggestions would be great. Thanks

All of your purchases are available free again from the stores. You can delete them and when you want to access them again just go to the store under purchased and select the ones you want. I do this all the time on my 16 gig ipad.

Common URL format for sharing file paths between Mac and Windows?

Hi -
I have to integrate several Macs into a Windows environment. We need to be able to copy and paste file paths to share between all machines. Is there a common URL format that can be used between the platforms?
On Windows, I have:
\\server\share\file
On the Mac:
smb://server/share/file
Thank you for your help,
Steve

On Windows you have what is known as a "UNC".
On the Mac, you have a "URL". It starts with the protocol to use "smb" then gives the path to the item using standard conventions.
UNC is Microsoft mainly.
The only way I know for Windows to use a URL is with an application like a web browser or ftp client.
On the Mac, you can use UNCs but they must be modified as follows.
In Terminal:
smbclient \\\\servername\\sharename\\filename -U username
And enter a password if prompted.
Notice that you must double up the slashes. This is due to how UNIX shells treat the backslash.
You will connect to the share, but it will only be in Terminal.

Thanks

"ORA-27040: file create error, unable to create file" is pretty explicit. Either the path doesn't exist or permissions for the path don't exist.
Also, I suggest that you verify if the target path has enough disk space for the database you are creating.
What about the memory allocation you have specified ? Is it adequate ?

The functionality that you require is not available to VBA/COM - it is only exposed via C/C++.
However, you could retrieve the ENTIRE page image to the clipboard and then use whatever VB/VBA methods you choose to grab a section of the image.
Of course, this all assumes that Adobe Acrobat is installed on each person's computer that will be using the solution since Reader does not have the necessary APIs and Acrobat can't be installed on a server.

Qmaster Compressor and Shared Storage

I've got Qmaster working on my compressor encodes and everything is working fine. What I want to know is whether there is a way to cut out the extra copy of data for the encode. All of my machines in the cluster have the same shared storage mounted on the desktop, but still my jobs get copied first and then encoded.
Is there anyway to configure qmaster, compressor and the cluster machines so they all use their local path for source files? And avoid the extra copy of the source files to the controller system?
Thanks in advance.

You want to make sure in Compressor, under Preferences, the Cluster Options field says Never Copy Source to Cluster. Assuming you have all of the correct permissions set and have the Shared Storage configured properly then it should work. "Should" being the key word.

3 Physical machines (blades) hosted within a separate physical quadrant
Both quadrants are extremely well connected, local, 10GBit/s fibre.
There is local storage in each quadrant, no storage replication takes place.
The 3 machines in the first quadrant are MS clustered with shared storage LUNs on a 3PAR filer.
The 3 machines in the second quadrant are also clustered with shared storage, but on a separate 3PAR device.
8 shared LUNs are presented to the cluster in the first quadrant, and an identical storage layout is connected in the second quadrant. Each LUN has an associated HAFS application associated with it which can fail-over onto any machine in the local cluster.
DFS replication groups have been set up for each LUN and data is replicated from an "Active" cluster node entry point, to a "Passive" cluster node that provides no entry point to the data via DFSn and a Read-Only copy on it's shared cluster
storage.
For the sake of argument, assume that all HAFS application instances in the first quadrant are "Active" in a read/write configuration, and all "Passive" instances of the HAFS applications in the other quadrants are Read-Only.
This guide: http://blogs.technet.com/b/filecab/archive/2009/06/29/deploying-dfs-replication-on-a-windows-failover-cluster-part-i.aspx defines
how to add a clustered service to a replication group. It clearly shows using "Shared storage" for the cluster, which is common sense otherwise there effectively is no application fail-over possible and removes the entire point of using a resilient
cluster.
This article: http://technet.microsoft.com/en-us/library/cc773238(v=ws.10).aspx#BKMK_061 defines the following:
DFS Replication in Windows Server 2012 and Windows Server 2008 R2 includes the ability to add a failover cluster
as a member of a replication group. The DFS Replication service on versions of Windows prior to Windows Server 2008 R2
is not designed to coordinate with a failover cluster, and the service will not fail over to another node.
It then goes on to state, quite incredibly: DFS Replication does not support replicating files on Cluster Shared Volumes.
Stating quite simply that DFSr does not support Cluster Shared Volumes makes absolutely no sense at all after stating clusters
are supported in replication groups and a technet guide is provided to setup and configure this configuration. What possible use is a clustered HAFS solution that has no shared storage between the clustered nodes - none at all.
My question: I need some clarification, is the text meant to read "between" Clustered
Shared Volumes?
The storage configuration must to be shared in order to form a clustered service in the first place. What
we am seeing from experience is a serious degradation of
performance when attempting to replicate / write data between two clusters running a HAFS configuration, in a DFS replication group.
If for instance, as a test, local / logical storage is mounted to a physical machine the performance of a DFS replication group between the unshared, logical storage on the physical nodes is approaching 15k small files per minute on initial write and even high
for file amendments. When replicating between two nodes in a cluster, with shared clustered storage the solution manages a weak 2,500 files per minute on initial write and only 260 files per minute when attempting to update data / amend files.
By testing various configurations we have effectively ruled out the SAN, the storage, drivers, firmware, DFSr configuration, replication group configuration - the only factor left that makes any difference is replicating from shared clustered storage, to another
shared clustered storage LUN.
So in summary:
Logical Volume ---> Logical Volume = Fast
Logical Volume ---> Clustered Shared Volume = ??
Clusted Shared Volume ---> Clustered Shared Volume = Pitifully slow
Can anyone explain why this might be?
The guidance in the article is in clear conflict with all other evidence provided around DFSr and clustering, however it seems to lean towards why we may be seeing a real issue with replication performance.
Many thanks for your time and any help/replies that may be received.

Hello Shaon Shan,
I am also having the same scenario at one of my customer place.
We have two FileServers running on Hyper-V 2012 R2 as guest VM using Cluster Shared Volume. Even the data partition drive also a part of CSV.
It's really confusing whether the DFS replication on CSV are supported or not, then what would be consequence if using.
In my knowledge we have some customers they are using Hyper-V 2008 R2 and DFS is configured and running fine on CSV since more than 4 years without any issue.
Appreciate if you can please elaborate and explain in details about the limitations on using CSV.
Thanks in advance,
Abul

Qmaster error: shared storage client timed out while subscribing to...

Here's my Qmaster setup:
computer 1: CONTROLLER, no nodes
- 8TB RAID hooked up via Fiber
- connected to the GigE network switch via a 6-port bond
- cluster storage set to a path on the RAID
computers 2, 3, 4, 5: RENDER NODES
- each computer has a 2-port bonded connection with the GigE switch
computer 6: Client, with FCS2 installed.
- connected with a single GigE link
I have set up this cluster primarily for command-line renders, and it works great. I submit command-line renders from the client computer, which get distributed and executed on each node. The command line renders specify a source file on the RAID, and a destination path on the RAID. Everything works great.
I run into trouble when trying to use Compressor with this same setup. The files are on the RAID, and all my computers have an NFS automount that puts it in the /Volumes folder on each computer.
I set up my Compressor job and submit it to the cluster. It submits sucessfully, and distributes the work. After a few seconds, each node gives me a timeout error:
"Shared storage client timed out while subscribing to [computer1.local/path to cluster storage]"
Is this a bandwidth issue? Command line renders work fine, I can render 16 simultaneous Quicktimes to the RAID over NFS. I don't see much network activity on any of the computers when it's trying to start the Compressor render, it's as if it's not even trying to connect.
If I submit the SAME compressor job to a cluster with nodes ONLY on the controller computer, it renders fine. Clearly the networked nodes are having trouble connecting to the share for some reason.
Does anybody have any ideas? I have tried almost everything to get this to work. Hooking up each node locally to the RAID is NOT an option unfortunately.

WELL I DO NOW!
Thanks. it's taken 6th months and several paid 'professionals' and then you come in here...swinging your minimalist genius. one line. one single line. and its done.
if you are in london, lets lift a beer or five together.
thank you sir. thankyou!

Problem of using OCFS2 as shared storage to install RAC 10g on VMware

Hi, all
I am installing a RAC 10g cluster with two linux nodes on VMware. I created a shared 5G disk for the two nodes as shared storage partition. By using OCFS2 tools, i formatted this shared storage partition and successfully auto mounted it on both nodes.
Before installing, i use the command "runcluvfy.sh stage -pre crsinst -n node1,node2" to determine the installation prerequisites. Everything is ok except an error "Could not find a suitable set of interfaces for VIPs.". By searching the web, i found this error could be safely ignored.
The OCFS2 works well on both nodes, i formatted the shared partition as ocfs2 file system and configure o2bc to auto start ocfs service. I mounted the shared disk on both nodes at /ocfs directory. By adding an entry into both nodes' /etc/fstab, this partition can be auto mounted at system boots. I could access files in shared partition on both nodes.
My problem is that, when installing clusterware, at the stage "Specify Oracle Cluster Registry", I enter "/ocfs/OCRFILE" for Specify OCR Location and "/ocfs/OCRFILE_Mirror" for Specify OCR Mirror Location. But got an error as following:
----- Error Message ----
The location /ocfs/OCRFILE, entered for the Oracle Cluster Registry(OCR) is not shared across all the nodes in the cluster. Specify a shared raw partition or cluster file system that is visible by the same name on all nodes of the cluster.
------ Error Message ---
I don't know why the OUI can't recognize /ocfs as shared partition. On both nodes, using command "mounted.ocfs2 -f", i can get the result:
Device FS Nodes
/dev/sdb1 ocfs2 node1, node2
What's the possible wrong? Any help is appreciated!
Addition information:
1) uname -r
2.6.9-42.0.0.0.1.EL
2) Permission of shared partition
$ls -ld /ocfs/
drwxrwxr-x 6 oracle dba 4096 Aug 3 18:22 /ocfs/

Hello
I am not sure how far this following solution is relevant to your problem (regardless when it was originally posted - may help someone who is reading this thread), here is what I faced and here is how I fixed it:
I was setting up RAC using VMWare. I prepared rac1 [installed OS, configured disks, users, etc] and the made a copy of it as rac2. So far so good. When, as per the guide I was following for RAC configuration, I started OCFS2 configuration, faced the following error on RAC2 when I tried to mount the /dev/adb1:
===================================================
[Root @ *rac2* ~] # mount - t ocfs2 - o datavolume, nointr / dev / sdb1 / ocfs
ocfs2_hb_ctl: OCFS2 DIRECTORY corrupted WHILE reading uuid ocfs2_hb_ctl: OCFS2 DIRECTORY corrupted WHILE reading uuid
mount.ocfs2: Error WHEN attempting TO run / sbin / ocfs2_hb_ctl: "Operation not permitted" mount.ocfs2: Error WHEN attempting TO run / sbin / ocfs2_hb_ctl: "Operation not permitted"
===================================================
After a lot of "googling around", I finally bumped into a page, the kind person who posted the solution said [in my words below and more detailed ]:
o shutdown both rac1 and rac2
o in VMWare, "edit virtual machine settings" for rac1
o remove the disk [make sure you drop the correct one]
o recreate it and select *"allocate all disk space now"* [with same name and in the same directory where it was before]
o start rac1 and login as *"root"* and *"fdisk /dev/sdb"* [or whichever is/was your disk where you r installing ocfs2]
Once done, repeat the steps for configuring OCFS2. I was successfully able to mount the disk on both machines.
All this problem was apparently caused by not choosing "allocate all disk space now" option while creating the disk to be used for OCFS2.
If you still have any questions or problem, email me at [email protected] and I'll try to get back to you at my earliest.
Good luck!
