Suddenly loss of connection when sharing files

[DaMerc91]

Hi

Since i reinstalled my Amahi home server, i'm having some serious problems when i'm exposing my server to high traffic. He never did that before, so i guess it has nothing to do with the system capabilities.

The configuration: 2.3 Ghz Celeron, 1024 mb, 10 Gig systemdisk, 1000 gig for data.

So when i copy a lot of files (starting from 5 gigs) to or from the server, the connection suddenly interrupts and gives me the error that the device cannot be accessed. When I stream video, same problem. I also use CD images placed on the server on different computers, so for some programs i'm very dependent of Amahi.

After a reboot however (which i do by the dashboard) everything is back normal, untill the next videostream or big file copy.

Is anyone experiencing the same problem, or has anyone a solution for this matter??
Thx a lot in advance!!

Grtz

details on the exact wording of the error please. as you can imagine this does not happen to many people (otherwise you will hear about it here in the forums!)

i routinely transfer 7+gb files (blueray disks, etc.), with ease and without any seeming issue.

hmm, what if you have an ssh connection open to the server and then start a file transfer. Is that aborted too? If the ssh connection is also dropped the fault is somewhere in the network stack (driver/software). Is there anything in the logs about this? Check /var/log/messages and the command "dmesg" for pointers.

I'm having a similar issue when transferring a large batch of files.

One or two of the files will transfer across and then I get an error (Win7 and OS X) that says the server cannot be accessed. In W7 when I click "try again" it will continually fail, but if I cancel and start another batch another file or two will transfer and then fail again.

Screenshot of the error I get in Windows 7. It is happening mid-file now as well. If the file transfer is unsuccessful, it doesn't show up as a partial file in the HDA window.

I watched /var/log/messages and the following was written to the log when I got the error:

I'm having the same problem as well.

[bigfoot65]

Looks like it could be Greyhole related. Have you upgraded Greyhole or invoked the mount_shares_locally script? Using that script might help.

sven86,

It helps if you can provide details. Just stating you have the same problem does not give us enough info to assist you.

Hi,

I seem to be experiencing this same issue. I'm running Amahi 7 on Fedora 19 and have greyhole installed. I'm trying to migrate my music over to my HDA via my windows 7 laptop. I had no issues with ~8G or so today, but this evening while trying to move another big chunk I get the windows error "Cannot access //hda/Music", and the "Retry" button fails. If I open a file browser I can navigate to the location no problem, so I don't know what it's complaining about. I hit "Skip", then the same thing happens with the next file. I see in this thread that others had a similar problem a few years ago, was a solution found? Is there a better way to move a large amount of data to the hda than good old copy/paste in Windows? Thanks!

Could be the size of your Landing Zone (LZ).

You can check to see how Greyhole is progressing with your files by doing the following as root user:

greyhole -q

You may need to do a smaller chunk of files and wait for Greyhole, or move your LZ to a bigger drive. No guarantee this is your issue, but kinda sounds like it.

Thanks for the reply. I don't think this is the issue as my LZ is on a 4TB drive with 2TB free.

I just tried again and it only got stuck once. After hitting Skip it actually continued this time and completed the transfer. Could be because there's no other network activity now? Not sure...
