lovingHDTV

Does anyone know of a copy program that reports the resulting bit rate for the copy? I would like to try this out by copying a large file from my XP box to the UnRaid server and see the resulting bitrate. Something similar to ftp reports is fine also. I've not had any luck googling this. thanks,

I just installed a new version of SageTV as they say they had an issue that would cause glitches ~5secs. I'll update if this was not the cause, but it sounds like this may have been a SageTV issue after all. sorry about the diversion.

My parity checks take ~3hours to complete also. That is why I was surprised at the rebuild time. I could see a 2x increase in time to rebuild over parity check, but what I saw was much longer. thanks,

Well 1600+ minutes later the tower did finally finish the rebuild. Is this a typical time frame to rebuild a 320GB drive? On the bright side there were no DMA errors during that entire rebuild time. That is amazing considering the issues I had prior to upgrading to the new version. Appears that the new version has made significant improvements for me.

While monitoring the rebuild process I've seen this error a couple times: Apr 15 19:06:14 Tower kernel: hdi: lost interrupt hdi is the drive being rebuilt.

Well, it did come back up and started a parity check. It then hung during the parity check. I've now removed the harddrive and am running unprotected. The drive never has had any issues with it up till now, it is about 4 months old. I took the drive out, rebooted, deleted the file I had the original trouble with, shutdown, put drive back in, rebooted. It is now rebuilding the server, and will be done in 1682 minutes! Wow that is a long time! Hopefully all will work out in the end.

I was saving a file to the tower and it hung. Windows gave an error about not being able to close the file. When I checked the tower it seemed to be OK, but I could not cd into the offending directory and syslog said: Apr 15 20:09:58 Tower kernel: hdi: lost interrupt I could also not remove the directory that had the broken file. I tried to shutdown and it hung, though another window I tried to reboot, and that hung. I then power cycled the machine and now I get the following errors upon rebooting: Apr 15 20:07:58 Tower kernel: md0: parity incorrect: 2308504 Apr 15 20:07:58 Tower kernel: md0: parity incorrect: 2308512 Apr 15 20:07:58 Tower kernel: md0: parity incorrect: 2308520 Apr 15 20:07:58 Tower kernel: md0: parity incorrect: 2308528 Apr 15 20:07:58 Tower kernel: md0: parity incorrect: 2308928 Apr 15 20:07:58 Tower kernel: md0: parity incorrect: 2314960 Apr 15 20:07:58 Tower kernel: md0: parity incorrect: 2314968 Ideas?

A little more information and some simple math: The file is created at a rate of 8GB/hr so that would be ~18Mb/s or ~11.25MB/glich. What is the block size for writing to the disk? Wondering if it is ~11MegaBytes is size. Maybe I'm completely off. As an aside anyone know of a program that will stream data to a file at a defined bit rate and report if the bit rate is unsustainable?

I use SageTV to record my TV shows. When I record a HDTV show to Tower, I have noticed that there are glitches in the recording every 4-5 seconds. They are like clock work, I actually timed them with my stop watch. These glitches in recordings only happen when recording to Tower. If I record do a local disk on my SageTV server, there are no glitches at all. Is there anything special that happens periodically like this on the UnRaid server? It seems to regular to be anything else. Ideas on what I can look at? thanks,

I know that when using winamp to playback mp3 files from disk2 on my UnRaid system, I get playback stuttering when I do directory listings of disk2. Just did this the other day.

Yep, your going to have issues with this. I bought it for the same reason and now only use it for backup storage. I've had to go and buy more disks to put back into my HTPC in order to get good playback. I'm hoping one day this will get fixed so I can use the big box in upstairs for what I bought it for A single gigabit network connection is plenty fast enough to support 4 feeds, even at HDTV resolutions. Currently the bottleneck is the UnRaid software.

I thought about picking up a couple, but I just need one for my MediaPC for some local diskspace. I had moved it from the PC into the UnRaid machine, but UnRaid cannot handle the demands of HDTV streaming so I needed to get a new drive for the local machine. I figure they will be cheaper in the future so I'll get more then Especially with the 1TB drives coming in the near future. Imagine 12 of those in an UnRaid box

I just picked up the $89.99 version from Fry's here in Austin. This version has a 16MB cache instead of the 8MB cache, they both come with a 5yr warranty. At the store it was limited to supplies on hand, but not per customer. They had a pallet of them

My syslog if full of these also. I was hoping the new code would fix it.

Hmm, how to hear the harddrive over the fan . . . Maybe this will work. I have done a similar thing when trying to find an odd noise on my car engine as I don't have a mechanics stethescope. Take a screw driver and place the metal end on the cage with the "spinning" hard drive. Then . . . I know this sounds wierd, but trust me . . . put the handle against your ear. This will transfer the vibrations from the drive to your ear. Then touch the fan momentarily to stop it from spinning. Maybe you can hear the drive spinning now?

Just some basics, please don't be offended. - hooked up the short IDE cable, and power cable inside the tray to the harddrive. - left the drive set for cable select. - installed tray into computer - turned key to locked/on - hooked IDE cable from MB/IDE card to tray - hooked power to tray - turned on computer Can you hear the harddrive spinning so you know for sure it got power. I'm not sure if the power LED lighting on the tray guarrantees that the drive is also getting power.

I know on my Cremax trays the key lock can be turned to two different locations. I have to turn mine all the way to the second location, not the first. Not sure if this makes sense.

Does anyone know of a program you can run on XP to check the samba disk IO performance? I just a program called HDTach to check harddrives on my computer, but can't find something similar for samba drives. thanks,

Take a look in the annoucements forum.

I figured this one out on my own There is no ftpd shipped on the flash drive, only trivial ftp. hmm

From what I've read it is recommended to compare Samba performance against FTP. Can we enable the ftp daemon temporarily to get some comparison numbers? They should be close in performance and is a good way to identify Samba issues.

Joe, My settings are the same as yours 66535 vs 65535 dave

I was looking at the samba settings that come with UnRaid. They do not match what is "recommeded" for max performance. Some of the differences are: SO_RCVBUF and SO_SNDBUF are recommended to be 8kB looks like we have 4kB. read raw and write raw are also recommended and I don't see those at all. What about setting MTU size or is that set elsewhere? My network can handle jumbo packets. I'm hesitant to change the settings as I don't know if UnRaid requires these settings in order to work. Has anyone changed any of these? thanks,

Any performance enhancements in this small release? I have my DMA problems worked around by doing the HDD shuffle. But I still cannot simultaneously record and playback a HDTV stream file without glitches. thanks,

Before releasing all the source code to the world, I would highly recommend that Lime-Technology go talk to an IP attorney in Sunnyvale who is familiar with the GPL. It will pay big dividends, as many GPL watchdogs do not understand the true requirments that ensure compliance with the GPL. My $0.02
