Filesystem bug or limitation?
Hello all, I'm playing with pharo filesystem and I run into an issue. I want to access the content of a remote windows folder from Linux, so my idea was to mount it using mount -t cifs, which works perfect, following that i thought I will access from pharo as any other directory. Instead of that if I try to make a fileReference with the mount point path I't says it deos not exists. But if I ask the parent folder for its childrends the mount point appears but not as a directory. Example: given: /mnt/remoteFolderMountPoint before mounting: '/mnt/remoteFolderMountPoint' asFileReference exists -> true '/mnt/remoteFolderMountPoint' asFileReference isDirectory -> true after mounting '/mnt/remoteFolderMountPoint' asFileReference exists -> false '/mnt/remoteFolderMountPoint' asFileReference isDirectory -> false Other curious thing is that if I do: '/mnt/' asFileReference children, it shows the mountpoint forlder that claims not to exist :S Any ideas? Thanks, Juan
I suppose (but Iâm just guessing), that is because it is not a real file but a kind of symlink. Esteban On 21 Jul 2014, at 16:53, Juan Ignacio Vaccarezza <juanvaccarezza@gmail.com> wrote:

From http://php.net/manual/en/function.is-dir.php... Just a note for anyone who encounters is_dir() returning false on CIFS mount points or directories within those mount points on 2.6.31 and newer kernels: Apparently in new kernels they've started using the CIFS serverino option by default. With Windows shares this causes huge inode numbers and which apparently can cause is_dir() to return false. Adding the noserverino option to the CIFS mount will prevent this. This may only occur on 32 systems but I don't have a 64 bit install to test against. So try using "noserverino" and testing before and after with " ls -i " Alternatively maybe compiling the VM with -D_FILE_OFFSET_BITS=64 would work https://bugzilla.samba.org/show_bug.cgi?id=7707 Also http://stackoverflow.com/questions/7600863/inode-of-directory-on-mounted-sha... https://lists.samba.org/archive/samba-technical/2010-December/075074.html HTH, cheers -ben
Ben, It worked like a charm with the noserverino!! Thank you very much! Juan On Mon, Jul 21, 2014 at 1:00 PM, <btc@openinworld.com> wrote:
