 |
|
I have just started receiving this error.
I am mounting a file share from a Windows 7 Ultimate 64bit (brand new install, fully patched up)
/etc/fstab line is | Code: | //trans-pc/D /mnt/trans-pc/d cifs defaults,user,rw,file_mode=0770,dir_mode=0770,iocharset=iso8859-1,credentials=/etc/samba/private/auth.trans-pc.lyall,noauto,gid=smb,noserverino 0 0
|
Then, I am trying to copy stacks of photos across using
| Code: | | cp --no-preserve=all --no-clobber --update --verbose --recursive --force --no-dereference "${DIGICAM_PICS}/Digicam Pics" "${mountPoint}" |
Things go along swimmingly for a while, then cp suddenly starts reporting | Code: | `/mnt/disk_02/Digicam Pics/The Pics/2006-01/(2006_01_02 14_20_39) p1020794.jpg' -> `/mnt/trans-pc/d/Digicam Pics/The Pics/2006-01/(2006_01_02 14_20_39) p1020794.jpg'
cp: cannot create regular file `/mnt/trans-pc/d/Digicam Pics/The Pics/2006-01/(2006_01_02 14_20_39) p1020794.jpg': Cannot allocate memory
|
The /var/log/messages contains
| Code: | May 11 22:20:01 lyalls-pc kernel: CIFS VFS: Unexpected lookup error -12
|
I was running gentoo-sources 2.6.36-r8, I upgraded to 2.6.37-r4, same error.
Suggestions?

I am now running 2.6.38-gentoo-r6, I just received the same error.
Interestingly, I unmount the share, attempt to re-mount it and then I receive
| Code: | IFS VFS: Send error in SessSetup = -12
CIFS VFS: cifs_mount failed w/return code = -12 |

Found the problem.
I had some files with question marks and double quotes in their filenames.
I use NTFS-3g and it quite happily allowed them to be created on my local disk and my USB external NTFS disk, but when I tried to copy the files to a windows share, where the windows machine was Windows 7, things went wrong.
Personally, I think an error such as "Cannot create file" would be preferable to CIFS VFS generating suprious messages and then not working until the system is re-booted. I am not sure where I should post this as a bug, kernel or in the Windows 7 share code, as it is apparently ok to create these characters in filenames if the program uses the Unicode API.
Edit:
Hmmm. Problem re-occurred, and I had cleaned up all the 'illegal' chars... back to square one.

I found a solution.
| Quote: | In HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management, set the LargeSystemCache key to 1 (hex).
In HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters, set the Size key to 3 (hex)
|
And then you have to restart some services and dependencies, or in my case I restarted Windows 7. |

Are you suggesting I have to change the registry settings on the target Win 7 machines? (the ones whose share I mount)?
