Re: [Bug 416313] Re: On samba of ubuntu-arm, large file copy fails
Apologies for not being clear and informative in the previous comment. Yes even in the debian samba package, the error is seen for vfat only - not for ext2/3. My preliminary opinion is that the issue is with respect to the way samba is currently handling large file transfers for vfat file systems and hence not necessarily a vfat issue. But as it is seen only on ARM platform, maybe something going haywire while handling large files because of some ARM specific peculiarities like alignment issues etc.?

Re: [Bug 416313] Re: On samba of ubuntu-arm, large file copy fails
Hi Chuck, Thanks for replying. Unfortunately the bug is still observed - i did some additional triaging. * The bug is seen only when the samba share exported is on a vfat file system - for ext2 and ext3 the large sized copy succeeds without fail. * I also tried using the samba package from debian-arm repositories(lenny-stable) - but there also the problem is seen. * Even if the error is thrown up - the file is still being copied in the background - or ftruncate'ing in the background (I suspect it is only ftruncating and filling the space with zeroes because of two reasons - one the md5sums do not match afterwards and two the code seems to be doing the same thing) - but as previously stated adding a patch to always call ftruncate64() in sys_ftruncate() does not fix the problem.

Re: [Bug 416313] Re: On samba of ubuntu-arm, large file copy fails
I am configuring it from the server side - and accessing it through windows client, so passing lfs option to smbmount is not possible or i am not aware of how to :) Update on the bug: I compiled debian package with --enable-largefile - no change. Then created a custom patch which would always call ftruncate64() in sys_ftruncate() - however client would still throw up error while copying large files.
