File copy corruption (seems solved) but system unstable

[Golfonauta]

Hello,

 

I have copied some files (images) form my PC to the unraid server and some of them have become corrupted.

 

I have made it from W7 x64 to a 5.12a unraid.

 

I first moved them to the server, then one was corrupted, I made a ctrl-Z to meve them back and a second one became corrupted, it was not a nice experience, I made it moving because i felt so confident with the system.

 

Any similar issue or possible reason?

 

Thanks

Run memtest on both your client and the server.

 

Oh, and try to post syslog

[mbryanr]

and provide your hardware setup and any add-ons.

Hello,

 

I'm sorry I was so unhappy with it that I used it as less as I could.

 

I know i have done bad, but, I have upgraded to the latest beta 5b14, is worse now (what are the developers doing?)

 

Current issues:

 

If I go to the webpage and push start to the raid in the main page, after some minutes I can´t access the server, I have to reboot it, and then I have no syslog

 

I will try now to run it with the monitor and keyboard connected to see if I can save the syslog once it starts going bad.

 

The unraid server memory has been tested, I'm testing it again right now.

 

My configuration is:

 

License: Unraid Server Pro

Case: Antec 9hundred

Motherboard: ASUS E35M1-M PRO (a nice motherboard with a lot of post telling issues)

RAM: 1 module 4GB

Storage upgrade: adaptec 1430SA

Disks: some western digital EARS and EARX some 1,5TB, some 2TB

 

I have attached the last boot syslog.

 

Thanks in advance.

If you can, use tera copy. enable TEST mode which will copy the file, then read it back to insure it was not corrupt.

if it fails it will not delete the source data.

Thanks for your advice, i know I can use some tools to enforce data safety when copying, but i sincerely want a reliable system. I have purchased a Pro version, I think I must have some support.

 

I see there is no patches for the betas, from beta to beta a long time and a lot of documents not maintained in the website.

 

Why don't they focus on making the system stable?

 

Is there not a debug mode? some way to make the syslog being writen to disk to view this errors.

 

Also, i have the system running memtes near 4 hours (no errors until now)

 

Thanks.

The system is pretty stable. The issue maybe something to do with your hardware and/or an inferior linux driver.

 

[Golfonauta]

Let's supose the software (unraid 5b14) is perfect and the issue is my harware (I don't use any other manualy configured driver, no idea how to do it also).

 

What do you propose me to do to know wich is the bad hw component? change it and try? (I will see if the software works with other hw, but not mine)

 

I was asking if there's a way to make syslog write to disk to troubleshoot the system.

 

Once I push start on the array it starts the paraty check, but for no aparent reason it simply crashes, the system does no longer reply over the network.

 

I'm reproducing it now because I want to try to copy the syslog from the terminal inside the system when it happens again.

 

Thanks,

Ruben

What power supply are you using with the system?  and how many disks are in server?

[Golfonauta]

I'm running 8 disks with a 500w+ PSU and with the low consumption motherboard it must be a lot of power remaining.

 

I've started the raid, and while it was irresponsive some time while checking the parity it finished the check and is up and running.

 

I'm going to make some tests and try to troubleshoot the corruption issues if they are still there.

 

Thanks

Post model number of your psu. If its multi rail there may not be lots of power remaining. I had a 700w psu but was quad rail so when i went above 6 disks i had to change it out.

Also how long have you run memtest?

 

Does the machine only crash during parity checks?

 

Post SMART reports for all your drives.

If it isn't, you should get a Corsair or Seasonic single rail power supply into the server. It sure sounds like a drive is acting up very badly and taking down the server, either because it is bad or because the power supply is bad.

 

Did you run the preclear script on all the drives? If you didn't run it, then I suggest you take a step back and do run it. You can use the connected keyboard and I believere its the <ctrl>F1 to <ctrl>F6 keys to access 6 different login screens. Run a preclear in each one and see what happens.

 

One other thing. Look up the network adapter on that motherboard and let us know what it is too.

I've run memtest for 4-5 hours (a pair of full tests I think) 0 errors.

 

I have found the first issue:

 

My W7 machine has an Atheros L1 Gigabit card, for some stupid reason this card is as bad as it breaks his own network connection (is a driver issue) I have aparently solved the issues by changing the adapter settings to:

 

Flow Control OFF

Task Offload OFF

 

I think this was probably also causing the corruption issues, and with the help of teracopy I will see if they appear again.

 

You can read about this in:http://www.sevenforums.com/network-sharing/5787-problems-atheros-l1-ethernet-adapter-win7-x64-5.html

 

But the setting that worked for me are the above ones.

 

The I have used teracopy to copy some data to the server, it looked fine, no errors, no network down issues.

 

I left the system 10 hours ago with some teracopy batch jobs pending, and when I have comed back the unraid was irresposive, also to console, and the second batch job is only half done, and 2 more jobs pending.

 

I've tryed to access the system from console for a while, looking if it just takes some time to recover from some sleep or whatever, but finally the only solution was to reboot it from the button.

 

I'm now waiting until it checks the parity again to continue testing.

 

I will look for the PSU specs, model and number, but it sounds so strange what you tell me.

 

Could you please specify me a PSU capable of moving at least 12 HDD? (I suposse my system will grown that much in the future if I solve this)

 

I've just purchased an Intel Nic with the intention to change the one in the unraid to solve the performance issues that some people says or to change the one it the W7, if it improves a lot I will provably purchase a second one to have all changed. the NIC is this one EXPI9301CTBLK

Do you know if it works well with unraid?

 

 

Thanks,

I'm going to substitute the PSU by a newer and more powerful one.

 

It had installed a Megiamagic 600W with 20A in the +12 line produced in October 2007.

 

I'm going to install to tooq 700W from my main system (not too nice for me to be making this)

 

 

Thanks.

[speeding_ant]

Hmm, 20a and being 5 years old might be the issue there. Never know, could be a CPU issue as well.

 

Once you've swapped the PSU, open one telnet window for each CPU core you have. Put this command into each window and leave it for a while:

 

yes > /dev/null

 

This will fully utilise one core per command, giving your CPU a bit of a work out.

 

Good luck!
