March 6, 200917 yr Hi I just setup my first unRAID box. It is my first time setting up a server so please bear with me. I am playing with the free version to get the hang of things prior to upgrading. I would really appreciate it if you can help me solve my problems. Background: First of all I loaded up unRAID perfectly fine. I access it through windows vista telnet or http://tower. I only changed the workgroup name to that of my home network through http://tower. I set up my hard drives in the devices page. Disk1=750GB WD RE2 GP SATA 3Gbps, Disk2= Maxtor 250G SATA 1.5Gbps. I have not set a parity drive because I have read that its better to transfer the files first before setting parity because it will be much slower to transfer the files. I only have these 2 drives currently installed and will add another 750GB WD RE2 GP parity after I figure things out. I started the array then formatted the two drives. Now the problem. When I transfer files to Disk2=Maxtor, transfer rates are fine everything perfect no worries. Instead when I transfer to Disk1=WD RE2 GP a quarter of the way in the transfer process, it starts moving EXTREMELY SLOW. At times it would finish at other times after a LONG time the transfer would popup and say that it cannot find the file that I was transferring (file is ~1-2GB). I tried different file sizes of different types but I keep getting this problem and only with the WD RE2 GP drive. After stopping, restarting, power down, reboot, etc... several times this still occurs. If it succeeds in transferring (after a LONG period) there are times when I try to delete or move a file within the disk and it says I do not have permission to do such a thing. Other times when I try to delete the file it gets deleted then when I refresh the folder the file REAPPEARS again and I thought I had just deleted it. I also noticed under the main page there are ERRORS under this disk only. Here is my setup: Intel Celeron 430 MSI P43 Neo3-FR Corsair XMS 2x512MB DDR2800 (Dual channel mode 1GB) 1x WD7500AYPS WD750GB RE2-GP 1x 6Y250M0 Maxtor 230GB SATA1.5Gbps ATI Rage Gigabit LAN network unRAID 4.4.2 Here is my syslog on different sites because I don't know how to attach it here and its really long. http://sharebee.com/0c4cdd5e or for direct http://rapidshare.com/files/205926578/syslog-2009March05.txt.html http://www.zshare.net/download/5660027087db4af1/ http://depositfiles.com/en/files/93or3b37k http://www.badongo.com/file/13717210 http://www.megaupload.com/?d=WHIU6Q9Z Here are some of my unRAID screens: The errors circled at certain times of testing can get high, into the thousands (x,000). I don't know if I should post this here or under a different area. Please tell me if I should post elsewhere. I really appreciate for all the help help. Thanks.
March 6, 200917 yr Unfortunately, your WD 750GB has problems, possibly serious. It reports almost immediately a media error (UNCorrectable), then a little later, reports an IDNF, which I believe is even worse, as I *think* it corresponds to a sector not found error, which can indicate corruption of the low level formatting. Now this syslog is rather short, and only reports 3 disk errors and no reasons at all for the slowness you detected, apart from the short delays in handling these errors. I would need to see the syslogs captured after what you detailed above, to provide better analysis. What is needed now is a SMART report for the drive (Disk 1, sdb), and a SMART long test. Please see the Troubleshooting page, Obtaining a SMART report section, for how to get the SMART report and farther down, how to start a SMART long test. Once you have tested the drive, and if it passes, then I would take it offline and run the Preclear Disk procedure on it, before I would trust it in my array. Completely unrelated, there is something else I noticed that looks possibly worrisome, this line and the line above it: Mar 5 22:47:57 Tower login[1284]: ROOT LOGIN on `pts/0' from `AC965835.ipt.aol.com' This address and the IP in the line above it do not look local. If you recognize them, then there is no problem. unRAID out of the box is not designed for exposure to the Internet, only to a local subnet, so I would make sure you turn on the security features, and password the root access at minimum, a very good password too and not just a simple one to keep the kids out. I'd also make sure you are behind a NAT router, but perhaps you already understand the issues, and have it under control. With what little I can see from here though, you look exposed and vulnerable, but I'm not an expert.
March 6, 200917 yr Author RobJ thanks for the help. I looked at the link you sent me for the SMART test. I tried doing it over telnet smartctl -d ata -tlong /dev/sdb | todos >/boot/smartB-long.txt but i get the response "smartctl: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: no such file or directory." It appears to be missing which confuses me cause I thought it came w/ the standard unRAID. I tried reinstalling unRAID on the flash and still get the same error. Can you link me somewhere where and how to add this to my stick so I can perform this function or if it a different problem. As soon as I get the above problem fixed and I run the test, if it fails does that mean I have to RMA the drive? As for security that you were talking about I set up a password for now. How would I go about and changing my address and IP to make it local. Is this under the settings tab and setting a static IP address or do I need to do something else. As far as the router goes I have a linksys WRT150N.

March 6, 200917 yr As for security that you were talking about I set up a password for now. How would I go about and changing my address and IP to make it local. Is this under the settings tab and setting a static IP address or do I need to do something else. As far as the router goes I have a linksys WRT150N. Unless you've opened up the permissions on your router, there is no was that anybody from AOL should have been able to log onto (or get to in any way) your unRAID server by going through your router. You should have the router's firewall protection enabled, and you should not have any PC on your lan designated in the DMZ unless you specifically want it to be the target of every virus and hacker in the world. If somebody from AOL logged into your unRAID server, and it was not you, then you can trust none of the files on it... (Really...) They could have done almost anything. You should turn off all "port-forwarding" unless you really know what you are doing. unRAID is not secure enough to just let the outside world in... I don't know if I'd do it with a password on the root account.... never-mind without one. Joe L.
March 7, 200917 yr Author Joe L. thanks I got the smartctl package installed and gonna do a long SMART test now. Question- When I perform the smarctl -d ..... on telnet and have it output to a file so I can see am I gonna see any progress report on the telnet screen. I checked the output file and it says it will finish in ... minutes. Do I check it some time after this period to see the report. Is that why I do no see anything on the telnet screen? You should have the router's firewall protection enabled, and you should not have any PC on your lan designated in the DMZ unless you specifically want it to be the target of every virus and hacker in the world. Ah I checked my router and it is NAT enabled and also firewall enabled. DMZ - I am not familiar with this. My router has it set to disabled. Is this right? You should turn off all "port-forwarding" unless you really know what you are doing. unRAID is not secure enough to just let the outside world in... I don't know if I'd do it with a password on the root account.... never-mind without one. The only have 2 ports opened for my torrent program and sopcast and I only open them on my own PC and not the others on the network. Unless you've opened up the permissions on your router, there is no was that anybody from AOL should have been able to log onto (or get to in any way) your unRAID server by going through your router...If somebody from AOL logged into your unRAID server, and it was not you, then you can trust none of the files on it... (Really...) They could have done almost anything. As far as AOL is concern there is another computer on my network that uses AOL frequently and I tried to transfer files from that computer the the unRAID box when I was testing it. Is that where this could have come from or should I fiddle with other things concerning this security which appears to be a problem. Thanks for the help.
March 7, 200917 yr The request for a long test NEVER gives any output of its own. You must let it finish and then request a normal smart report to see the results. Joe L.
March 7, 200917 yr Author Update: I just finished my SMART test and it told me it has failed. Does this mean I have to RMA this drive? I do not really not what SMART really is. I am currently reading up on it. Results: http://sharebee.com/0e4944d1 === START OF READ SMART DATA SECTION === SMART overall-health self-assessment test result: FAILED! Drive failure expected in less than 24 hours. SAVE ALL DATA.
March 7, 200917 yr The drive is worthless, needs to be replaced. It has already used up all or most of its spare sectors. It also indicates an ATA Error Count of 53344! You WANT to RMA it.
March 7, 200917 yr Author Thanks for all the help I am gonna RMA this drive for now and hopefully when I get it back it will not give me any problems. Kinda funny since this drive is less than a year old. Just wondering I have a current WD drive on my current computer which I was planning to migrate to the server and I used the WD Disagnostics program to test the SMART status before transferring. This test is just as good as the one on unRAID right so I can test and have it pass here first before transferring it to the box right. Also, I am not to familiar with Linux so I was wondering if you can also help me with some commands. I want to do this with each of the hard drives I put in the box. The hard drive devices are indicated by hdx for IDE drives and sdx for SATA/SCSI drives correct. So when I list them in telnet: ls -l /dev/sd* ls -l /dev/hd* it shows more devices than is connected such as sda, sda1, sdb, sdb1, ... How do I know which which of these actually refer to my connected hard drive and how do I relate these to each of my hard drives connected (in other words how do I know if sdxx refers to the maxtor drive or the WD drive). On a side note I was wondering if you knew if there is a way to SMART test my 2x RAID0 drives because I may be getting better drives for my current computer and transferring the ones in RAID0 to the server. Thanks.

This test is just as good as the one on unRAID right so I can test and have it pass here first before transferring it to the box right. If the test just says PASS/FAIL, then no, it is not as good. If it shows you all the SMART attributes and lets you see their values, then yes, it is probably equivalent.

How do I know which which of these actually refer to my connected hard drive and how do I relate these to each of my hard drives connected (in other words how do I know if sdxx refers to the maxtor drive or the WD drive). ls -l /dev/disk/by-path Shows you the drives by their model and serial number and the device they are linked to. ls -l /dev/disk/by-id Shows you the drives "disk controller" ID and the device they are linked to. ls -l /dev/disk/by-label Lists the devices that have "volume labels" that the devices they are linked to. (Typically, only the flash drive will have an entry here and it MUST have a volume label of "UNRAID" for unRAID to start up properly. On a side note I was wondering if you knew if there is a way to SMART test my 2x RAID0 drives because I may be getting better drives for my current computer and transferring the ones in RAID0 to the server. Thanks. Sorry, can't help you there. Check the raid controller's manufacturer web-site for guidance. Joe L.
March 8, 200917 yr Author Joe thanks a lot for the help. Those command made clear of my drives that are connected. If the test just says PASS/FAIL, then no, it is not as good. If it shows you all the SMART attributes and lets you see their values, then yes, it is probably equivalent. It gives these information: Is this good enough not sure how much SMART information is really needed to determine drive status/integrity. If good enough, what should be my main concerns to look at in event of failure or possible failure?
March 8, 200917 yr As a SMART report, it looks fine, this drive is good. But this is not your bad drive, so this must be your good WD? The bad one has a serial number ending in 762. By the way, this is not a test, it is just a display of the current SMART values. What tests are available to you in the WD software?
March 8, 200917 yr Author This is actually a good drive. I just wanted to know if this test was good enough for drives I will add now and in the future because it is more convenient for me at the moment. I just showed that before I actually do the test. The WD Diagnostic program just lets me do a QUICK or EXTENDED test, doesn't say anything specific to test for.
