Not syncing new files on CentOS 6.3

[software2]

I have set up fileconveyor on a CentOS6.3 box which I intend to use to host several Magento commerce platforms.

FileConveyor is configured and works on startup (correctly syncing all the changed files) but does not seem to be picking up file changes while running.. See this simple test, where I:

• Ran fileconveyor
• Uploaded two images to the source directories
• Waited 5 minutes with no activity
• Shut down fileconveyor
• Immediately re-ran fileconveyor
• The two new files were instantly sync'd

....

Any advice would be appreciated

By chance are the files you're watching on a mounted windows share? If so it wont detect the changes. File Conveyor uses inotify to be alerted to changes on the linux file system. On startup I'm pretty sure it uses polling, which is why it finds the files after restarting.

I'm not sure, not being a massive linux person.. as far as I am aware it is the local file system.. Would the mount results answer that question?

~$ mount
/dev/xvda1 on / type ext3 (rw,noatime,barrier=0)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
none on /proc/xen type xenfs (rw)

How efficient is polling? Worst case is I am going to have to set a cron to restart fileconveyor!

@software2 also first contacted me via e-mail, and for once I briefly replied there instead of directing him

I suspected the same as @edmooney:

It sounds like you're on a Linux system, which would mean that inotify is what powers instant file system change tracking. That doesn't work on networked file systems like gluster and NFS. Any chance you're using something like that?

I'm no Linux expert myself either, so I don't know how to interpret the mount output you provided, @software2. But it sure looks like you're on a file system where inotify does not work, or you must have somehow disabled inotify.

Could you please verify that inotify is working correctly by installing the inotify-tools package and then doing something like http://exyr.org/2011/inotify-run/? :) Thanks!
