Error code 8084 when copying large files from VNX servers

Hi,
We are experiencing problems when attempting to copy large files from our central VNX servers (EMC) using the connection format of smb://<host>/.  With Mavericks this will be SMB2, presumably.  Anything over a few MB in size fails with the error:
The operation can’t be completed because an unexpected error occurred (error code -8084)
Looking in the Console logs we see the following:
kernel[0]: smb2_smb_read_write_fill: len got reduced, must be running low on credits
If we attempt this on OS X Mountain Lion or below we have no problems.
If, with Mavericks, we connect using the format cifs://<host>/ then file transfers work.
Has anyone come across this before?  Thinking I should also post a bug...
Cheers,
Ian

  • Error code -36 when copying large file

    Aperture (Apple's pro photo software) stores all of it's data (pictures, metadata, etc) in what appears to be a large file called the Library. In fact, it's a large folder with all of the contents hidden so you don't mess around with it. I back this file up periodically to both an internal and external drive. After a hard drive failure and recreating my whole machine, everything seemed fine and Aperture is working normally. I have tried to drag copy my Aperture Library (rebuilt from my Aperture vault, a back up file created by Aperture) file to my internal second drive, a process that takes about 2 hours (300 Gb). The drive I'm copying to has over 451 GB available and was freshly formatted during this rebuild process. A little more that half way through the drag copy I get the following message.
    "The Finder cannot complete the operation because some data in “Aperture Library” could not be read or written, (Error code -36)"
    Here's what I've done to so far.
    1. Aperture has a function to repair permissions and rebuild the file, done both several times.
    2. I found (by looking at all 20,000 plus pictures) some corrupt picture files and deleted them, then repeted step one.
    3. Tried a duplicate file on the same drive, same error.
    Thoughts? Help? I can't find anything on a Mac OS error -36.
    By the way, I'm running Mac OS 10.5.8 and Aperture 2.1.4 on a Quad Core G5.

    This what it means:
    Type -36 error (I/O Errors (bummers)
    This file is having difficulty while either reading from the drive or writing to the drive. The file
    may have been improperly written data to the drive or the hard drive or disk may be damaged.
    This is almost always indicative of a media error (hard error on the disk). Sometimes (rarely) it is transient.
    Solutions: Try copying the file to another drive. Use a disk recovery software, such as Disk First Aid to examine the disk. You can try rebooting with all extensions off. Once in a while this will allow you to read the data. The file in question should be restored from a backup that was stored on a different disk. Regular backups can reduce the time to recover from this error.

  • Error message -36 when copying large  files from Firewire drive

    I have kept several large audio files as backup on an external LaCie Firewire drive. When trying to copying them back, almost all of them starts to copy, then stops and (after a minute or so) report error message -36.
    I have run both Apple's Disktools and the latest Diskwarrior, but no errors are reported. I gues the audio files must have become corrupted... What do you suggest that I do? The contain valuable audio information that I really don't want to get lost.

  • Copying hangs when copying large files from DVD

    I'm having trouble copying large files (>2GB) from DVDs to my built-in hard drive. When I drag the file icon from the DVD window to the desktop, the progress bar pops up almost immediately, and says "0 KB of 2.3 GB copied" and "Estimated time left: 1 minute" -- and then it just sits there, doing nothing. In some cases, after five minutes or so of inactivity, the copy finally begins... but most of the time it never does. Force-Quit doesn't help; the only way out is to do an emergency restart and try again.
    This problem began when I upgraded to Tiger, and several members of my office group have been experiencing the same problem on their own computers as well.
    I've poked around the forum looking for answers but the only thing I could find that looked related was a conflict between iSight and some third-party external hard drives... but none of us have iSight, and none of us are using third-party external drives, so clearly that's not the issue we'rehaving.
    Any help out there?
    iBook G4   Mac OS X (10.4.6)  

    Michael, I occasionally notice anomolous behaviour when files get dragged between volumes. Mostly the copying window shows an accurate and immediate indication of what's going on, but other times it just looks like nothing's happening, the display never changes, yet, it is in fact copying the files over. Now, if you're copying 2gb files from DVD to HD, it's gonna take some time, more than 5 minutes, so I'm wondering how long you've left it before forcing it to quit?

  • OS X 10.4.7 server: Samba leaking ram when copying large files from windows

    Hi.
    I'm having problems with:
    Copying files from windows clients to OS X Server 10.4.7 uses up the RAM needed for the files to be copied.
    If I copy a 3GB file, it uses 3GB of RAM
    If I copy a 5GB file, it uses its 4GB of RAM, plus VM.
    If I copy 11GB of files (that is several little files, plus some big by dropping a folder to the share), it consumes all the RAM the machine has, and because of VM paging, whatever other clients are reading from the disk (XRaid) start to have hiccups.
    The RAM of the machine NEVER gets flushed after the copying has finished. So Samba is unusable as it is. I have four Xserves with 4GB of RAM, with 4 XRaids connected each one to each Xserve with its Apple Fiber Channel card and cables.
    I already did the ack=0 thing, got the size of inet.tcp.sendspace and rcvspace to 8388608 and the buffer to 16777216.
    The transfers rates are up to 70MB/s with 2 channel 1gb trunking, and at very sustained rates..
    We are using these to edit video content (DV 25) in Sony Vegas with 2 or 3 clients for each server.
    Any suggestions?
    Thanks very much.

  • Error code -8062 while copying large file in OS X 10.8.4

    I have to copy a very large Time Machine backup file to another disk before resetting RAID 1 on my LaCie 4 GB 2Big drive. File is about 350 GB. After getting through about 2/3rd of it, I am getting an error saying " .. you don't have permissions to copy some items..." and when I click OK, then I get an error code - 8062.
    I am using MBA Mid July 2011, OS X 10.8.4, Time Machine backup on LaCie 4 GB 2Big RAID 1 drive to FreeAgen 1 TB.
    I would appreciate any thoughts on this. It has happened twice now and since the process takes a very long time, I have wasted three days on it now.
    Thanks you.

    Although the documentation says you can copy Time Machine backups in the Finder, it's very slow and sometimes doesn't work at all.
    Launch Disk Utility, open the built-in help, and search for the term "Duplicate." Follow the instructions. All existing data on the destination volume will be erased. That shouldn't be a problem, because you don't want to mix backup and non-backup data on the same drive anyway. Turn Time Machine OFF in its preference pane while copying the volume.

  • Error code 36 when moving big files

    getting error code 36 when moving big files from my mbp (10.6.8) to my external hard drive. have tried using the sudo command in terminal, but it doesnt work. what do i do?

    sorry about that
    I'm moving movie files around 800mb++ to HFS+ and NTFS formatted drives. no problems when using the NTFS drives with other computers but i cant really test the HFS drive on another computer since im the only one with a mac.
    I've tried:

    but to no avail.

  • Unresponsive system when copying large files drive-to-drive (x86_64)

    I'm running Arch x86_64 on a quad core Xeon processor/P35 motherboard w/ 4 gigs of RAM.  I also have two SATAII, 7200 RPM HDDs.  For the most part, Arch is a VERY responsive platform.  I am noticing some really odd unresponsiveness that only happens when I copy large files from one hdd to another hdd.
    Symptoms:
    -Mouse cursor skips (doesn't move smoothly)
    -Windows such as firefox or shell don't move smoothly across the screen if I move them
    -Keyboard lag - as I type this post ) my fingers are going faster than the text is appearing
    Once the copy is finished, everything is normal again.  I swear I read someone else reporting this behavior, I just can't find it. Two questions:
    1) Is normal for the x86_64 kernel?
    2) If not, what can I tweak to remedy it?
    EDIT: Ack!  Found the post I remembered reading:

    if the file is bigger than 4gig(uncompressed) then u need swap partition, as the first thing it does is copy the file to memory and if it overflows it is bad. then your server is 1/3 options, either server/middle/desktop. if it is server, it doesn't care what framerate u get on X. then there is the timer. I'm running mine at 300 but arch's default should be 1000. the higher it is the more it "checks" what needs to be done with files, events, etc. then there is the file system type and block size factor. if ur block size is really low like me(1024k) then ur hd has to write more times(on and off) just to write out the huge file. so for huge files, format with huge block size(4096k?) so that the hd does less work.

  • When copying raw files from Extreme IV card to hardrive, finder copies a few files then exits task and wipes the card clean of all images.

    When copying raw files from Extreme IV card to hardrive, finder copies a few files then exits task and wipes the card clean of all images.  Have tried new card and card-reader to no avail.  Have done this many times on other macs with no problems.
    Can edit files off the card, in CameraRaw, prior to 'copying' them, ie can 'save as' to the hard drive, so files seem okay on card, before I try to copy them using copy and paste.
    Running OS 10.8.3 on a new macbook pro.

    Rita,
    The process for determining what is causing the files to be corrupt can be a tedious one depending on the following:
    1. Can you review the images on your camera's LCD screen without problems? If not then the problem is most probably either a corrupted/faulty memory card or a faulty camera. If this is the case then your best bet at recovery (of sorts) is to use a program such as BrezzeBrowser from BreezeSys to extract the embedded jpeg versions of the corrupted RAW files from within each RAW file. Chances are, you won't manage to actually repair the corrupted RAW file but the jpegs are better than nothing.
    2. If the images review ok on your camera but are corrupted when viewing on your computer and there seems to be no other problem with other files on your computer then it may be either a faulty card reader or usb/firewire cable between the card reader and the computer that is the culprit. Try the card reader with a different cable and also try a different card reader to determine the cause of the corruption.
    3. If your symptoms are that you get different files corrupting over time when viewing them on your computer then the problem may be any one of either failing RAM memory, hard disk, hard disk controller or IDE/SATA hard disk cables. This is where the troubleshooting can be pretty tedious testing then eliminating each item from the list of suspicious pieces of hardware. Try the card and card reader on an altogether different computer to see if the files transfer correctly to that computer. If so then the problem lies with your computer hardware. If you haven't already done so at this stage, backup all your important data immediately (hopefully you keep backs anyway).
    Hope this helps.

  • Error code 0 when copying a large file to a Mac OS Extended formatted drive

    I always back up my photos manually by dragging a folder containing many folders containing many photos into an external drive that I immediately formatted as Mac OS Extended (Journaled) the day I bought it 2 years ago. I now run into a Error Code 0 when I do this. The "mother" folder is 240 GB in size. As I stated, this drive has been formatted for the Mac, so I don't understand why it's (apparently) running into a problem peculiar to FAT32-formatted drives. My iMac has 16 GB of RAM, of which 10 GB was free, the last time I tried to do this.

    Well, you did mention...
    so I don't understand why it's (apparently) running into a problem peculiar to FAT32-formatted drives
    I kind of had to assume at that point the source drive was the one you formatted as Mac OS Extended two years ago, and the target drive was FAT32. If not, then I'm not sure why you mentioned FAT32 at all.
    In that same thinking, error code 0 is directly related to FAT formatted drives.

  • Error code 50 when copying from TC to external HDD

    Hi all, I bought a 3tb TC and backed up about 1.3tb worth of data onto it from an external HDD, I then formatted the external HDD to FAT 32 as I found out that TC does not like to work with FAT 32, no matter, the hard drive ois fixed now. However, when I go to copy all the data back onto the external HDD. i get "an unnexcpected error occured error code -50" or something like that, but the error code is definetly 50. I got this error when trying to copy the movies through, they are MKV files, I checked all the names and I dont think there are any problems with them.
    the setup so far is as follows. Externall HDD --USB--> Time capsule.    All operations are being executed through an imac.
    HELP ASAP will be greatly appreciated.
    Cheers

    Error codes are really hard to figure out.. but i think it will be due to permissions.
    See http://pondini.org/TM/C10.html
    It is an error from TM but I think it comes from underlying OS..
    Can you copy files to this disk from a source other than the TC.. try copying a file from the TC to the Mac and then from Mac to the external disk.. but make sure it is plugged directly into the mac.. if you have issues look carefully at permission. And format/partition type.. do use GUID partition not MBR Or the older Apple systems.

  • TC and WD500 External drive - Locks up when copying large files

    I have a TC with a Western Digital 500GB my Book connected to the USB port on the TC that I use for network Storage. Everything works fine until I try to copy large files or directories from the Finder mounted share. After the copy freezes the external drive can no longer be seen by airport utility. If I look at disks it sees the disk but no partition. I have to power cycle the external drive to have TC see the drive again. Then I disconnect the drive and plug it in directly to the MAC and run disk utility and his repairs the journal. I have to do the repair every time it locks up. Should the external drive be formatted different or does it have to be connected to a USB hub. Or is this just a bug with the TC and afp ?

    I have this very same problem.
    I tried to copy a 4GB+ folder from the Macbook to the 500GB MyBook attached to my TC and it froze.
    Now the the files on the MyBook are invisible when attached to the TC ("0 Items") but are available when the drive is connected directly to the Macbook. I have run disk utility but it hasn't helped. The disk is FAT 32 formatted and the files on the MyBook are still invisible over the network.
    When the drive attached to the Macbook directly I can see a 'phantom' file with the same title as the 4GB+ folder I'd tried to copy. This file is "ZERO KB" and it cannot be deleted (error code -43).
    Anyone have a clue what is happening here?

  • Keep losing connection to Time Capsule while copying large files from Vista

    I keep getting "Error 0x80070079: The semaphore timeout period has expired" while trying to copy large (1GB+) files from my Windows Vista Business 64 bits laptop (this OS is running on a MacBook Pro using BootCamp) wirelessly connected to a Time Capsule. The wireless connection to the Time Capsule is interrupted when this error occurs and then I can re-establish the connection. The problem seems to only occur when I copy large files or when I copy many files at once.

    I believe that this problem is resolved as I describe here:

  • Clients Time-Out When Retrieving Large Files  From Our PureFTPd Server

    Hi, not sure if this is the right place to get help, but didn't know where else to look. And let me begin by saying I'm not a server admin by trade, but that is the role I've fell into at a design firm. So please bear with my lack of knowledge on some of the more technical details.
    We have OS X Server 10.4.11 running here with PureFTPd installed and managed through PureFTPd Manager application. It has been fairly reliable for us for the last 2-3 years once the initial setup craziness was complete.
    But lately we've had 2 clients say that they've had difficulty downloading larger files from us. They get a time-out or error message on their end. They are most likely using Windows Explorer on a PC to do the transfer, which has always been the easiest method for our clients.
    One client had no problem getting files up to 14MB or so. But when trying to download a certain file that was about 80MB, it would not work. I tried different things here, and she tried multiple times, but no luck. I tried zipping the file to see if that would help, but no luck.
    Then another client had a similar problem today with a file that was only 25MB.
    We don't send large files very often, so I'm not sure if this is a recent thing or not. It seems like we've received some large files recently though.
    In PureFTPd manager, I usually leave all of the fields in the Transfers tab empty for all users. I didn't see anywhere else that would seem to impart a file-size limitation.
    • Any ideas at all?
    • If not, any other forums that I could search for help on? It looks like the developers site for PureFTPd Manager hasn't been updated in a year or two.
    Thanks in advance!

    Some years back I had trouble at a customer that had a ADSL using PPPoE connection to their ISP.
    Their router/modem (Speedtouch) couldn't cope with the LAN MTU when they sent files out so I had to lower it on their computers (running Panther?) ethernet interface from 1500 to 1492 (PPPoE overhead was 8 byte). The communication used to stall at about 25MB but the MTU change helped resolving that.
    My guess is that the router had to fragment (split in two) all outgoing packets it recived from the LAN computers and it just couldn't cope after a while.
    In your case it can be other network related things too like maybe needing traffic prioritizing, if receiving a lot of traffic from Internet and trying to send at the same time.
