guitarlp Posted June 3, 2008 Share Posted June 3, 2008 I added a new cache disk today. It's actually an old disk of mine... but before I decided to start using it I ran Smartctl and this is what it output: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 1 Raw_Read_Error_Rate 0x000b 200 001 051 Pre-fail Always In_the_past 0 3 Spin_Up_Time 0x0007 132 104 021 Pre-fail Always - 3900 4 Start_Stop_Count 0x0032 099 099 040 Old_age Always - 1343 5 Reallocated_Sector_Ct 0x0033 163 163 140 Pre-fail Always - 581 7 Seek_Error_Rate 0x000b 200 200 051 Pre-fail Always - 0 9 Power_On_Hours 0x0032 082 082 000 Old_age Always - 13412 10 Spin_Retry_Count 0x0013 100 100 051 Pre-fail Always - 0 11 Calibration_Retry_Count 0x0013 100 100 051 Pre-fail Always - 0 12 Power_Cycle_Count 0x0032 099 099 000 Old_age Always - 1297 194 Temperature_Celsius 0x0022 117 253 000 Old_age Always - 33 196 Reallocated_Event_Count 0x0032 185 185 000 Old_age Always - 15 197 Current_Pending_Sector 0x0012 198 175 000 Old_age Always - 102 198 Offline_Uncorrectable 0x0012 174 167 000 Old_age Always - 1084 199 UDMA_CRC_Error_Count 0x000a 200 253 000 Old_age Always - 0 200 Multi_Zone_Error_Rate 0x0009 167 155 051 Pre-fail Offline - 1133 I'm pretty sure that's a bad disk right? Multi-Zone error rate is 1133, offline un_correctable is 1084. Current pending sector is 102. From what I understand, none of those are good to have. Link to comment
WeeboTech Posted June 3, 2008 Share Posted June 3, 2008 I would not trust my data on this drive. You can possibly get the drive to work for a while by dd'ing zeros to the whole drive. If pending sectors goes down to 0 you may be ok for a while. after writing zeros to the whole drive, I would do a -tlong test on the drive to be sure. Link to comment
guitarlp Posted June 3, 2008 Author Share Posted June 3, 2008 I figured it was no good. It's an old disk that I haven't used in over a year or two but I thought I may be able to get some use out of it. Oh well... Looks like I'll pick up a cheap drive from Fry's so I can start using the cache feature. It's not even worth trying to see if I can make it work. I would hate to copy a bunch of stuff to unRAID to find out the next morning the disk failed and everything I thought I had copied had failed. Better to be safe then sorry though Link to comment
Rob_Esc Posted June 3, 2008 Share Posted June 3, 2008 I'm running 4.3.beta6 Pro. I have anomalous temperature readings on two of my disks and didn't really think too much of it, since I've read in other threads that it's not that big of a deal. It was nagging at me, however, and after reading this thread I ran smartctl on all of the disks in my array. Being a Linux noob, I'm not sure how to interpret the results, but I see some things that concern me. Could someone examine these attachments and help me to identify any problems? Link to comment
Rob_Esc Posted June 3, 2008 Share Posted June 3, 2008 The rest of the attachments: It's parity and data1 disk are reporting temps of 65 celcius, whereas the rest of the disks are at about 38 degrees. Link to comment
SSD Posted June 3, 2008 Share Posted June 3, 2008 I don't see anything that gives me big concerns from your smat captures. I (personally) do not like to run my drives too hot. Even 40C is too hot IMO. Consider adding some active fans blowing air between your drives. If those 65C termperatures are believed, that would be way too hot. Not sure what that attribute 190 is, but smartctl is definately not too happy about it. My guess is that it is not a big issue. I wonder if there is a newer version of smartctl that understands some of the newer high capacity drives and can actually identify this attribute? Link to comment
WeeboTech Posted June 3, 2008 Share Posted June 3, 2008 Run a -tlong test on the drives in question. 65c is way too hot, Not sure if it is accurate, I know some o fmy drives will shuitdown at 55c. I lnow there is a later version of smartctl 5.38 heres the output on one of my drives.

I added this disk as a cache disk. Once added unRAID formated the drive but it didn't do it's normal clearing like it does with my data drives. Is this normal or should I worry about the errors?

Bad disk? Edit 2: i releaized copying a 866 MB file from unRAID to my PC wasn't grabbing the data from the drive... it was grabbing to data from memory since the file size was so small. I copied an 8 GB movie to the cache drive and compared it to the file on my PC. It passed with no errors for 5 tests. Right now I'm running smartctl -tlong so hopefully when that's done I'll have some more information. Edit 3: Hmmm... found this link from another thread: http://en.wikipedia.org/wiki/S.M.A.R.T.#Known_S.M.A.R.T._attributes it states: "Do note that Seagate drives often report a raw value, that does not mean it is in failure and show high value even as a new drive." So maybe these high values are ok because the drive is a 500 GB Seagate drive. Thoughts? Link to comment

SSD Posted June 4, 2008 Share Posted June 4, 2008 I don't think you have anything to worry about. I have two of these seagate 1T drives. I've posted the smart output below. These RAW values are difficult to interpret without documentation. For example, it could be that different bits in the value mean different things, and seeing it as a number if totally meaningless. I'm just not sure. If the drive is testing as okay, I just wouldn't lose too much sleep. If you're seeing lots of remaps and/or drive errors - or if the drive is telling you it is failing - THEN I'd be worried! WeeboTech - do you have a link to the newer version of smartctl? Perhaps it would display different results if the drive is in the smartctl database Disk1: 1 Raw_Read_Error_Rate 0x000f 117 100 006 Pre-fail Always - 125573338 3 Spin_Up_Time 0x0003 091 089 000 Pre-fail Always - 0 4 Start_Stop_Count 0x0032 100 100 020 Old_age Always - 112 5 Reallocated_Sector_Ct 0x0033 100 100 036 Pre-fail Always - 1 7 Seek_Error_Rate 0x000f 052 051 030 Pre-fail Always - 47246454664 9 Power_On_Hours 0x0032 098 098 000 Old_age Always - 1826 10 Spin_Retry_Count 0x0013 100 100 097 Pre-fail Always - 4 12 Power_Cycle_Count 0x0032 100 100 020 Old_age Always - 69 184 Unknown_Attribute 0x0032 100 100 099 Old_age Always - 0 187 Unknown_Attribute 0x0032 100 100 000 Old_age Always - 0 188 Unknown_Attribute 0x0032 100 099 000 Old_age Always - 4295032834 189 Unknown_Attribute 0x003a 100 100 000 Old_age Always - 0 190 Unknown_Attribute 0x0022 072 061 045 Old_age Always - 505020444 194 Temperature_Celsius 0x0022 028 040 000 Old_age Always - 28 (Lifetime Min/Max 0/17) 195 Hardware_ECC_Recovered 0x001a 048 036 000 Old_age Always - 125573338 197 Current_Pending_Sector 0x0012 100 100 000 Old_age Always - 0 198 Offline_Uncorrectable 0x0010 100 100 000 Old_age Offline - 0 199 UDMA_CRC_Error_Count 0x003e 200 200 000 Old_age Always - 0 Disk 2 ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 1 Raw_Read_Error_Rate 0x000f 119 100 006 Pre-fail Always - 205589542 3 Spin_Up_Time 0x0003 091 086 000 Pre-fail Always - 0 4 Start_Stop_Count 0x0032 100 100 020 Old_age Always - 112 5 Reallocated_Sector_Ct 0x0033 100 100 036 Pre-fail Always - 1 7 Seek_Error_Rate 0x000f 066 060 030 Pre-fail Always - 4739075 9 Power_On_Hours 0x0032 098 098 000 Old_age Always - 1821 10 Spin_Retry_Count 0x0013 100 100 097 Pre-fail Always - 2 12 Power_Cycle_Count 0x0032 100 100 020 Old_age Always - 64 184 Unknown_Attribute 0x0032 100 100 099 Old_age Always - 0 187 Unknown_Attribute 0x0032 100 100 000 Old_age Always - 0 188 Unknown_Attribute 0x0032 100 100 000 Old_age Always - 0 189 Unknown_Attribute 0x003a 100 100 000 Old_age Always - 0 190 Unknown_Attribute 0x0022 072 065 045 Old_age Always - 521797660 194 Temperature_Celsius 0x0022 028 040 000 Old_age Always - 28 (Lifetime Min/Max 0/17) 195 Hardware_ECC_Recovered 0x001a 050 039 000 Old_age Always - 205589542 197 Current_Pending_Sector 0x0012 100 100 000 Old_age Always - 0 198 Offline_Uncorrectable 0x0010 100 100 000 Old_age Offline - 0 199 UDMA_CRC_Error_Count 0x003e 200 200 000 Old_age Always - 0 Link to comment

Not sure how that will work. Many thanks to WeeboTech for posting this!!! I finally got around to installing this today. Since I know so little about Unix, even something simple like this took some time for me. So I decided to post this to help anyone else that wants to use this version. Note that smartctl 5.38 recognizes newer drives much better than 5.36. I highly recommend upgrading to this version. Here is what you need to do: 1 - Download this library http://packages.slackware.it/package.php?q=12.0/cxxlibs-6.0.8-i486-4 and put on your flash disk. Put it in a directory called "/custom/usr/share/packages" on the flash disk. 2 - Rename the file to have a ".tgz" extension instead of a ".gz" extention. 3 - Go to a telnet (putty) prompt and enter the command "installpkg /boot/custom/usr/share/packages/cxxlibs-6.0.8-i486-4.tgz" 4 - It should not give any errors 5 - Download the updated smartctl program (HERE) and unzip the program inside. Put on the root of your USB drive. 6 - Run the command, for example, "/boot/smartctl -a -d ata /dev/device/sda" 7 - (To be able to run it after a reboot). Edit your "go" script in your "config" directory of your flash disk, and add the "installpkg" command from step3. Copying files from your windows computer to your flash is easy, just navigate to "//tower/flash" from Windows Explorer. You can then just drag and drop or cut and paste. Update: Package directory changed to match the standard. Link to comment
WeeboTech Posted July 6, 2008 Share Posted July 6, 2008 The suggested directories are /boot/custom/usr/share/packages. /boot/custom/bin In the future there will be some of us who will install packages in those structures. I even have an idea for a package manager to allow you to enable/disable them from a browser interface. Hopefully one day we'll have a CGI capable http server so I can implement that. See this Wiki article for more information. http://lime-technology.com/wiki/index.php?title=Third_Party_Boot_Flash_Plugin_Architecture Link to comment
SSD Posted July 6, 2008 Share Posted July 6, 2008 Package directory updated in the prior post to follow suggested directory structure standard. Link to comment
