I am transferring folders from a Mac mini that is connected to a USB 3.0 hard drive and the network on a CAT 5e cable to a gigabit switch, that switch is connected to my Apple Airport Time Capsule which is directly connected to the unRAID server. I have been copying several folders from the USB 3.0 HDD via this connection to the server. I have reached a folder that will transfer very slowly and locks up right before 500 MB then just trickles at .1 MB every few seconds.

 

This is 2 of 3 topics I am posting the others are the machine name change and one of my ethernet connections not always registering. I list these other two in case they are related.

 

Thank you.

You could simplify things by connecting your unRAID server to your switch. Does that make a difference?

I have tried switching to the switch instead of the router and it showed no change. The current situation is that when I attempt to delete the folder I have been trying to copy over from the share it shows a status bar of deleting 1 item and never finishes or shows a progress. When I attempt to copy the folder and write over it, it no longer asked me to overwrite the folder it remains stuck on the Preparing to copy. I have disabled the bonding and have only one ethernet cable connected and rebooted the server with no change.

After moving the device I wish to copy from to another machine and copying it first to the machine before trying to copy it to the server. Also copying other files to other shares in the server the problems seems to be with a particular share, it will not let me delete or overwrite the folder iPhoto Library. The problem seems to be isolated here with this share no matter which computer it will not delete or overwrite the folder.

You can't delete a folder that's in use.

Can you define a folder in use? I reboot the server, start the array then go in and try to delete the folder iPhoto library in the share Pictures. The file never deletes and I cannot overwrite it.

One containing open files. Files opened by the iPhoto application, for example.

 

Or it could be a permissions issue.

 

Your original problem was slow writes to the server. Is that fixed now?

Thank you. I right clicked on iPhoto Library selected Move to Trash and I left it for hours. When I came back, it was deleted. That is progress. I attempted to copy the folder over again from my MacMini to the share. The procedure after some initial time started to transfer several megabytes a second, then slowed. It always seems to be right before the 500 MB mark. Presently it has been running for 15 minutes and it shows a status of 493.6 MB of 92.27 GB - About 7 days. I have copied other folders to this share and the speeds were much faster.

It really depends on the contents of the folder. A single 92 GB file will copy much much faster than a folder containing 92 million 1 kB files, for example. Network attached storage is much less efficient in dealing with many small files than few large files. Try it for yourself, by making a test folder with test files inside, though perhaps with a less extreme example! Your photo library probably consists of many thousands of files a few megabytes in size so that would fit somewhere between the two extremes. There could be some problem with your iPhoto library, but that would be a Mac thing, not related to unRAID.

Thanks. I am copying the 92GB to a USB 3.0 drive and I will plug it directly into the unRAID box. I am unsure on how to move the files on the unRAID box. After some initial reading I heard Putty but seems to be a PC only program. Any suggestions for Mac? The transfer started slow from the MacMini to the USB 3.0 drive just like the attempt to copy it to the unRAID box but it has picked up and will be done in an hour or so. The usb drive is formatted NTFS.

I use Terminal, which is included with OSX in the /Applications/Utilities folder. You can telnet into your unRAID server:

From there you can use Midnight Commander (it's worth reading up on it first) to copy files between disks or, if you're comfortable with the Linux command line you can use cp or rsync.

 

Since your external drive is formatted NTFS you might like to install the Unassigned Devices plugin first as I'm not sure that unRAID supports NTFS natively.
