Q: Strange problem when copying files to NAS

Hello all. I have a strange problem when trying to copy files from my intel iMac to my Seagate NAS. I am copying files from my HD and when the file is nearly copyied i get an error message saying that the file can't be copied because it is already in use by another application. Well... it surely isn't. I try copying them by ftp (Filezilla) and everything works fine. I can then access them through my media server but !!!! NOT THROUGH MY iMac!!!! It is like the files are not there!!!! But they definetely are! I tried fixing the disk permissions, rebooting NAS, iMac etc but nothing seems to solve the problem. Is there any suggestion of what might be wrong? I am under Mavericks and i am pretty sure that the problem started after the update. When copying from my external USB hard drive to my iMac HD everything works fine. The problem is from my iMac to my NAS.

iMac, OS X Mavericks (10.9)

    Same problem here, on a completely clean install (not an upgrade) of Mavericks. NAS is a QNAP TS210. Only on large files, and moving folders to folders is fine, it's only moving invididual large files that is the issue. Unfortunately I work with audio, so move lots of large single files to and from my NAS as a normal part of my workflow. Very frustrating.

     

    Did not have this problem with previous versions of MacOS.

    Hello,

     

    i could solve the same situation/problem by change the view mode of the folder from icon to list (in the source and in the target folder too)

     

    Preview funcrion was also switched off.

    I've got this issue on two seperate systems( two Macs, on seperate networks each with their own NAS ), both after they have been upgraded to Mavericks.

     

    I have it set to list view by default and have turned off Preview too, but I still get this stupid 'file in use' error and it's driving me nuts

    I've had this happen a few times too, but not anymore; I suspect it's a Finder quirk. Try these two things and preferably when doing so, use a file that consistently gives the problem:

     

    1. Try unix copy and move commands from terminal, eg

    cp <local file path> /Volumes/<NAS share>/<folder path>  Try the same for mv (move) - both of these should not give such an error.

     

    2. In Finder, with list vew and no preview, locate the file in the right pane. Make sure you DO NOT select it; if the file name line is all blue, click once on something else to remove the solid highlight of that line. Access the context menu of the file by right-click (two-finger trackpad push or however you do right-click equivalent on your hardware). When you get the context menu this way, you'll see that the file line is bordered in blue, not solid-highlighted. Choose the copy and then paste (or move) using the same idea (without solid-highlighting) in the destination folder. If you don't get the context menu when trying to paste/move into the destination folder, double-click the folder to enter it and use either empty space in the right pane to get the context menu or use the "gear" button on the menu to do the paste/move.

     

    Maybe worth a shot for you as I don't have the problem with Finder anymore using it this way

    Thank you for taking the time to reply. It's very much appreciated.

     

    I missed one important piece of info from my problem and that's that I'm trying to copy multiple files ( about 1500 ) so it'd be nigh on impossible to do them one at a time

     

    I have managed to copy a couple of files that were likely candidates for causing the trouble trouble, by using your second suggestion, but it's not the file that's the issue, as the next file in the list did the same thing, when I tried to include it in a mulitple copy.

     

    Like you say, it looks to be a Finder 'bug' and one that is making me reach for the ML install disc

    So for multiple files, putting them in a local folder and trying the same Finder trick but on the folder instead of selecting multiple files... does that work?

    disabling ' show icon preview' in Finder - View options seems to work for me

    That's done the trick, SilverSkyRat. I need to move them from the folder they copied across in, into the folder I want them in the NAS, but that's going to be a while, as they're still copying.

     

    Thanks for the suggestion and help.

    Well, I originally had my Lacie 2Big Network 2 NAS providing its shares via SMB but I didn't like how the Mac created its resource forks as separate files (all those "._" files). By the way, I believe that if the NAS is only providing SMB V1, then that is what the Mac (without any additional configuration) will use after negotiation, because that's all the NAS has in that instance. So I changed the NAS to share via AFP. If memory serves correctly, I had the "cannot finish" issue on both sharing protocols.

    Hi all,

    this isn't just a NAS problem, I'm getting it on two macs with Mavericks trying to copy over large video files, then if I can get it to copy people with older systems (10.7) get the problem when they try to copy my files to their system.

     

    It seems more likley to happen with larger files, I know it's not a NAS problem as I don't use them, there might even be a relationship between this problem and the "USB unmounting after sleep" problem, which means it's more than possible it's a finder problem.

    It isn't enough to put it in list view, you also have to pick view options and clear "show icons" as well.

     

    Seems to have fixed the bug i have been working around for weeks!

     

    Thanks

    Also, I need to add, that it has significantly sped up my copies.

    I am also have the same problem mentioned in this thread here.  Very frustrating.  I removed the show icon preview but continue to have issue.  I do think this is getting close though.  I feel as if something on the os level is reading the file as it is being copied and causes the file not to transfer.  I can turn right around and transfer the file to a HD on the same Mac with no problems.  Only when I try to transfer to NAS OR another machine on the network.  Currently transfering via smb.  Sometimes the move to another folder on local machine and then transfer to NAS works but what a pain.

     

    If I use Carbon Copy Cloner to back up the same files, it works just fine.  It is only when using Finder that it fails.  Unfortunately Carbon Copy is not a simple solution.

    I don't think it has anything to do with multiple files.  I am having the same issue.  When I quit out of every application the message does go away.  My mac is a clean install of Mavericks with no real modifications.  Just the normal nessessary apps installed like Adobe, etc.  But for me it is also happening when copying to a NAS.

     

    The most annoying thing about it for me though is that it doesn't fail and pop the message up until AFTER it's already done all the work of copying the file.  It's not like it tells me straight away.  My files are multiple gigs, so that's several minutes of waiting before finding out.

     

    And with multiple files beign copied at the same time, when it hits that error it stops, so onlyt the files up to that one copy successfully and the rest don't.

     

    Even if the file is open somewhere it should still copy.  I can't figure it out.  I can't MAKE it happen with a test file.  These are files that I did just have open and did just modify.  But even if I close out of the app first sometimes it happens and sometimes it doesn't.  But it's usually only one file at a time that will do it.  Like FINDER is what has it open for some reason.
