Hi All,
Just to set the context I have worked in tech support for over 15 yrs :). Sorry for the long post but it should be able to allow you to reproduce the problem consistently. I do not believe this is a networking issue per se caused by the transport layer (ie setting workgroup pieces up) as when I was downloading a file directly to the drive using BitTorrent from my laptop it was consistently showing 200k per second transfer rate yet browsing to it using windows failed every time. I belive it to be a filesharing problem based on the filesystem api’s not the network transport layer.
//Begin detailed diagnosis//
Ok so I have owned the WDTV Live with no problems what so ever until yesterday. I have had this device since before christmas. I use it as a Media server mostly burning dvd’s and numerous photo’s itunes et al. I am (was) really happy with the system. I have hooked up a 1TB WDTV Mybook drive everything was working splendidly except for network drop outs every couple of hours when transferring data from my NSLU2 to the drive (300Gb of photos and Itunes takes it out of you!), I put this down to something arcane somewhere. (Note 1). All of my laptop’s/computers are setup as WORKGROUP computers after reading the posts here I enabled DDE networking.
Yesterday my troubles started. I can intermittently brows my attached drives, sometimes it will freeze, sometimes it will work fine then stop. Browsing down two sublevels on this system will freeze.Strangely a file on my drive will show up as a folder (Note 2)
What changed?
Couple of things:
1)My 1TB drive suddenly went over 500GB In size. My drive is the default format as delivered by WD I don’t know if this is FAT32 or NTFS.
2)I was transferring files at around 200k per second from the internet to my drive this really killed it.
3)I installed the latest firmware.
Symptoms:
1)The browsing problem everyone sees here (Note 1 above)
2)Connecting to the wdtv through the drive when having the sharing problem the interface is very very slow
3)Filesystem on drive when browsing from windows seemed to be corrupted (Note 2 above). Note I took the USB drive out of the system and connected it direcfly to the PC, used the onboad WD Tools to verify the drive and file structure and it was ok, i even played the avi file stated to be a folder.
How to reproduce problem Consistently:
1)Use something like bittorrent to transfer a file directly to the drive from an attached windows machine, this forces multiple connections to the drive, or use TeraCopy on a large file…
2)Have more than 500Gb on the drive (Supposition).
3)Have over 30,000 files in the drive sub-system (Supposition)
Resolutions:
1)Turning off the WDTV Share on network fixes the slow interface problems. Whilst this fixes the playback if I had wanted to buy a none networked media streamer I would have bought the WDTV, not the Live version.
2)As an experiment I removed my WDTV 1TB drive and attached my 500GB (Non-Full) drive which has my movies on it, guess what the browsing was fine again from the laptop no drop outs.
3)I then reattached my 1TB drive (Leaving my 500Gb drive attached) guess what problem re-occured instantly within a couple of minutes.
4)I have deleted the .wdtv directory on multiple occassions and it still has the issue.
Conclusion:
1)If it was transfering files at high volume that caused the problem, then my test(3) above would have still worked fine as I rebooted the machine to clear any issues.
2)If it was a network sharing issue test (2) above would have not worked as it shared out the new drive ok.
3)If it was a database indexing problem (4) would have fixed it.
I therefore conclude that the linux system within the drive cannot handle file systems > 500GB or filesystems with over a certian number of files within the directory structure. I do not believe it is a networking drop out at all.
If people could post the size of their drive usage on here it would help inform the debate I feel as I feel quite strongly it is a fileserving problem not a networking problem my (note 2) above would confirm this (the system detailing a directory as a file yet attaching and running diags on the drive shows it to be an avi that I can play) and the fact that the cpu seems to go into meltdown (evidenced by the slow browsing of the interface or playing files on the drive locally with stutters).
So if you have the issue (or not) please put in the size of your drive and the number of files and the format of the drive NTFS/FAT32 if we see a common thread emerging I guess thats it :).
Pity about this, such a nice box, guess I’ll be treating it like a WDTV disconnecting my drive, attaching it to Lapto, what a darn pain.
Thnks
