I noticed the other day that two of my movies that were copied to the unraid array from a computer running couchpotato were not completely copied. Put this down to a couchpotato error. However, I have now noticed that a movie that was complete and had been watched all the way through is suddenly only 200meg instead of the original 6 gig.

 

Unraid server does not have any download plugins installed. This is all on a seperate machine. I have run a parity check over night and have no sync errors. I am a bit at a loss as to what might be causing this. Why would a file suddenly shrink?

 

I have included my syslog. Any help would be appreciated. I am very worried that this might be happening to random files all over unraid. Wife would not be happy if I lost the wedding photos!

 

Thanks for taking the time to read.

I do not see anything weird in your syslog. What you are experiencing is very unlikely to be an unraid error.. As soon as a file is on the array unraid does not touch it anymore, so there really is no tool that could be doing something wrong..

 

Are you absolutely sure you watched the same version of the movie, on the same location ?

 

Something like this could happen when a tool like couchpotato would move an incompleted file out of a temporary download directory.. But ofcourse it would then be impossible that you watched it fully before..

I am fairly certain it was the same version of the movie. Though I suppose it may be possible that couchpotato tried to download it again for some strange reason.

 

So this problem could not be caused by a faulty drive?

Everything is possible in the multiverse... But corruption is such a way that the file is readable but to shirt would kind of a lucky shot..

 

In any case: get SMART reports on the drives, then it is easy to see if something is going wrong there..

Ummm ... couchpotato downloading?  I thought that cp searched and then passed the download request to a downloader.

 

I have seen such things happen when playing around/moving torrents with Transmission.  If the torrent file is is reoaded, then Transmission can delete the already downloaded file(s) and start the download again.

 

As Helmonder says, it is extremely unlikely that unRAID has chosen a file to truncate, or has corrupted the file such that it is still readable - much more likely that an application is causing this.

No idea what might have caused this, but if you are relying on unRAID as your only copy of your wedding photos, then you are doing it wrong.  unRAID is NOT backup (neither is any other format of RAID.) 

 

Get yourself some online backup of some description and store ANOTHER copy of your important stuff there.  There are plenty of plugins for unRAID which will assist with this.

 

 

Ofcourse there are wedding photos that may get lost :-)
