February 1, 201115 yr So, I have setup Unraid and have my 2 new 2TB drives syncing for parity. I also have 3 other drives NTFS 1tb+, that I want to add to the array. I am having problems finding the right wiki to show me how I can add all my data. I guess I can put them in one of my other computers and run the files through the network or plug it in locally. Can someone point me to the wiki that shows the steps on how to do that? I really don't want to lose anything, or wait a day for everything to transfer. I've tried to google and search, but I might not be putting in the right info, b/c I can't find it. I follow the wiki to install unMenu, so I have that going for me if that helps. Thanks, BNB

February 1, 201115 yr Author I feel fairly comfortable with it. I've played around with linux a few times and used to use DOS. So, it is currently running the parity from a 2TB blank drive to a 2TB blank drive, can I cancel it, hook up one of the drives, follow these instructions and start the parity again?
February 1, 201115 yr Yes, and as the guide strongly points out, make sure you DON'T assign these disks in unRAID until all your data is safely on the array and parity is synced.
February 1, 201115 yr After parity is built make sure you run a parity check before trusting the array. The parity build blindly writes the data. The check reads and validates it worked properly. It is also important to look at the smart reports from each drive in the array to make sure you don't have serious drive issues looming, and also to examine the syslog for signs of errors.
February 4, 201115 yr Author So, I decided to just copy over the stuff from one pc to the Unraid server. I have a lot of errors. Can anyone help me out trying to decipher the errors. There are 173. Thanks. http://pastebin.com/CP4jiLv0
February 4, 201115 yr Check the troubleshooting link in my signature and get a smart report on the drive that is throwing the handle_stripe read errors. Also check your cabling for power and data to make sure everything is secure. If you could give us a full system spec breakdown that would also be helpful (motherboard, PSU, RAM, etc)

Thanks. http://pastebin.com/CP4jiLv0 It appears as if your parity disk, (disk0) has reported "media errors" to the OS, and it in turn has shown them to you as "read" errors. You probably should get a "smart" reports on that drive and see how many sectors are un-readable. on the command line: smartctl -d ata -a /dev/sda post its output. Optimally, you should run that disk through the preclear_disk.sh script to get an idea of its true health, but to do that you'll need to un-assign it from your array. The preclear_disk.sh script will completely zero the drive, and wipe any existing parity calculations from it. It will give you a report on the health of the drive. When you re-install/re-assign the parity disk to the array it will completely re-write parity to the disk. Joe L.

The motherboard processor are about 3 years old, I can't remember what they were at the moment. I have 3GB of ram. Thanks
February 4, 201115 yr OK, I will try this. It was a brand new drive. Lately it seems about 1 out of 5 new drives is being reported a defective in some way. Some DOA, some die during the initial preclear burn-in, some fail SMART tests. I'll be curious to see what the SMART report shows. Joe L.
February 4, 201115 yr Author So originally on the smart directory, I got it didn't exist, now I get this: Sorry: cannot run smarthistory. The /boot/smarthistory/smarthistory.php file does not exist. Can someone clue me in on how to install it. thanks,
February 4, 201115 yr Author smartctl -d ata -a /dev/sda with this command, I can't read the whole thing, but I see Commands leading to the command that caused the error were: Then 3 READ DMA EXT and 2 WRITE DMA EXT
February 4, 201115 yr Author so, I downloaded smarthistory.zip and put it in smarthistory directory. I get this: e </BODY></HTML> 0 It is almost done copying stuff from my other PC, so I guess I will try the preclear. thanks

You did not need to download or install anything to get a smart report. You can use the disk management page in unMENU or click on the "sm" link for that drive on a myMain plugin page.
February 4, 201115 yr Author So I finally got Smart installed. This is the output: Disk 1: OK - ATA_Error_Count is Disk 1: OK - Raw_Read_Error_Rate is 99767143 Disk 1: OK - Spin_Up_Time is 0 Disk 1: OK - Start_Stop_Count is 55 Disk 1: OK - Spin_Retry_Count is 0 Disk 1: OK - Power_Cycle_Count is 49 Disk 1: OK - Reallocated_Sector_Ct is 0 Disk 1: OK - Seek_Error_Rate is 2390717 Disk 1: OK - Temperature_Celsius is 36 (0 15 0 0) Disk 1: OK - Current_Pending_Sector is 0 Disk 1: OK - Power_On_Hours is 73 Disk 1: OK - Offline_Uncorrectable is 0 Disk 1: OK - UDMA_CRC_Error_Count is 0 Disk 0: OK - ATA_Error_Count is 11 Disk 0: OK - Raw_Read_Error_Rate is 67429206 Disk 0: OK - Spin_Up_Time is 0 Disk 0: OK - Start_Stop_Count is 52 Disk 0: OK - Spin_Retry_Count is 0 Disk 0: OK - Power_Cycle_Count is 49 Disk 0: OK - Reallocated_Sector_Ct is 0 Disk 0: OK - Seek_Error_Rate is 2420063 Disk 0: OK - Temperature_Celsius is 32 (0 14 0 0) Disk 0: OK - Current_Pending_Sector is 0 Disk 0: OK - Power_On_Hours is 73 Disk 0: OK - Offline_Uncorrectable is 0 Disk 0: OK - UDMA_CRC_Error_Count is 0 No alerts from Smarthistory. 2 device(s) active, 0 sleeping, 1 did not return SMART data.

I am running the parity check after copying more stuff over, and if I run into errors, I guess I will run the preclear. That is not a smart report. You did not need to install anything. "smartctl" is part of unRAID, has been for a very long time. (The history stuff you installed probably will not hurt, but it is not needed) Since you have unMENU, use the "Disk-Management" page and click on the "Smart Status" button for the drive. Or, on the myMain page, click on the "sm" link in the "Info" column on the line associated with the disk Or, on the linux command line type smartctl -d ata -a /dev/sda and post its output. None of those have anything to do with the smart history package you added.
February 4, 201115 yr Author Thanks for clearing that up. This is the report from my drive 0. It is still running a parity check since I just finished copying a bunch of stuff. http://pastebin.com/37vwWC2J
February 4, 201115 yr Author So, I'm adding a third drive after copying everything over on the network. It is clearing the drive. Is this different from Preclear. Do I have to run that on the drive after this finally finishes?
February 4, 201115 yr So, I'm adding a third drive after copying everything over on the network. It is clearing the drive. Is this different from Preclear. Do I have to run that on the drive after this finally finishes? If you are saying that unRAID is clearing the drive, then yes, it is different. 1. You array is off-line while it clears the drive. 2. It does not perform a "read" of the drive to allow SMART to detect un-readable sectors. The first time you'll be reading them is when you put your data on the drive. 3. Because it does only about one third of the work of the preclear script, it runs in about 1/3 of the time. It does not perform a pre-read, or a post-read/verify. Unfortunately, once you have assigned the disk to the unRAID array you may not use the preclear script on it, since it would overwrite your disk. So, too late to use the preclear script now. If you want to use it you'll need to un-assign the new disk from the array. Joe L.
February 4, 201115 yr Author Crap, so should one run preclear on every drive before they add it to the array? What happens if it is not run? How long does preclear take to run on a 1TB drive? Thanks
February 4, 201115 yr Crap, so should one run preclear on every drive before they add it to the array? If you do, the array will only be off-line for a few minutes. A huge advantage. What happens if it is not run?Same as every other disk drive that is not surface tested and burned in prior to being put into service... you take you chances it will work. How long does preclear take to run on a 1TB drive? Probably about 16-18 hours. Joe L.
February 4, 201115 yr Author So, to add a new drive I'm expecting a 1 day process until I can use it, after preclearing it and clearing it and copying data.
