September 16, 201015 yr Author i hate days like this one. now that i unassigned both discs out of my array (one was parity and one data) after i precleared both i can't figure out how to get a format button back in unRAID it tells me i have to place both discs back in the same slots as before (disc assignment) or it is invalid. and after this there is only a start button there is no "RESET the array". i really dont wanne go through the installation again. are those drives really precleared, as said in the report-mail? i mean you talk about 12-40 hours for one disc and my report is missing drive speed values as well as it was finished after 3,5 h. now that they are precleared and even if i assign the same drives to the same slots as before in unRAID, if i press start it takes a while. then i press refresh and it is back on the old screen, where i could press start.

There is... It is a command line command initconfig i really dont wanne go through the installation again. are those drives really precleared, as said in the report-mail? i mean you talk about 12-40 hours for one disc and my report is missing drive speed values as well as it was finished after 3,5 h. now that they are precleared and even if i assign the same drives to the same slots as before in unRAID, if i press start it takes a while. then i press refresh and it is back on the old screen, where i could press start. You said your server was un-responsive. It might have crashed. Who knows. To tell if the drives are really pre-cleared type preclear_disk.sh -t /dev/sda preclear_disk.sh -t /dev/sdb etc. The -t option tests if they have the pre-clear signature. It takes just seconds to run for each disk. Joe L.
September 16, 201015 yr Author you were right. i checked with the test parameter and it said "NOT precleared"........... i so much wish i could understand why and what happened maybe its not the best idea to start with an linux system like unRAID if you never before worked with linux. but i will get this done. i will so much get this done! thanks for your patience and advices again. edit: just in case: if preclear disk tells me, that there is no valid partition found - right before i write down "Yes" - and it starts the reading test after that, will it create a partition by itsself? reading makes no real sence if it has no partition on it, or am i wrong? after re-jumpering those drives my partition seemed to get lost
September 16, 201015 yr Do not run anything if you have not sorted your cooling problems and your beeping motherboard from the other thread. Running WD20EARS at 55°C is dangerous
September 16, 201015 yr you were right. i checked with the test parameter and it said "NOT precleared"........... i so much wish i could understand why and what happened maybe its not the best idea to start with an linux system like unRAID if you never before worked with linux. but i will get this done. i will so much get this done! thanks for your patience and advices again. edit: just in case: if preclear disk tells me, that there is no valid partition found - right before i write down "Yes" - and it starts the reading test after that, will it create a partition by itsself? reading makes no real sence if it has no partition on it, or am i wrong? after re-jumpering those drives my partition seemed to get lost Adding the jumper changes the starting sector (see this website for a decent explanation - http://www.pcper.com/comments.php?nid=8113) so yes, your previous partitions are gone as far as the OS is concerned. The purpose of reading (then writing, then reading again) every sector of the drive prior to using it for storage is to check it for potential errors prior to trusting it to store your data. On more than one occasion users here have discovered brand new drives exceeding the SMART thresholds for reallocated sectors and sent them back for replacement. Obviously its much better to discover your disk is faulty before you start storing your data on it (and much more likely it will still be under warranty).
September 16, 201015 yr You can read the disk sectors without having to partition a disk. It is done every day. In the same way you can write them without the disk being partitioned. (It is, in fact, how you partition a disk) However, part of the pre-clear signature is the disk properly partitioned, so yes, the pre-clear script does partition the disk as expected by unRAID. It is one partition, starting at sector 63 and extending to the full size of the disk. Users have discovered disks that have bad electronics, where reading them back after writing zeros to them occasionally returns a non-zero value. Those drives will drive you crazy, because once in the array they just show up as occasional parity errors. The problem is that parity is corrected to be in sync with the bad data being supplied by the drive and you can't tell which drive is the culprit. I'd say that 99% of the drives show no issues at all. I just don't want that remaining 1% causing me to pull out my hair.
September 16, 201015 yr Author regarding heat: i never ever had problems with really hot drives. not that i dont believe in your words. i really do and will take the advice very seriously. it's just that i build and work with windows pcs for decades now and i never needed to plug in case-fan for my drives. here is what i encountered regarding heat over the last years: my current pc runs with 6 HDDs that are all next to each others, letting them getting really warm. my pc runs with spinned up discs 24h a day and i never had a bad disc in the last 15 years there is no cooling stuff inside my pc besides CPU/GPU/PSU cooling via an active fan even my graphics card is going to be replaced by a passive cooling one this month (radeon HD 5770). same goes for other devices. lately i have had tested a bad programmed pc game,that startet to push my graphicscard to its limits. guess what it could take? my graphicscard ran at 102-104°C for > 1hour before i recognized it same goes with my CPU. there was that day when i booted and my CPU fan didnt start. my CPU got up to 100°C until my motherboard shut down. and again - no errors after that. guess i like heat more than noise. luckily i could increase the RPM of my server-case-fans, so every disc is at 43-46 °C for now. more fans will be added soon regards
September 17, 201015 yr Author some hours later.. it seems to run this time both discs are about to get cleared with zeros (~40 % done by now) one disc at around 75 MB/s the other one at around 82 MB/s sound better than 10MB/s
September 17, 201015 yr Author millions of hours have passed since i started pre-clearing at the moment it runs for 19h and is in the post-read @25% for both discs if the post-read speed remains the same, i will be rdy around 2 o'clock tonight, running over 30 hours for each disc the very best invention within unRAID is the ability to get status reports for every piece of information by mail. thats the only light at the tunnel of preclearing discs. see u soon
September 17, 201015 yr millions of hours have passed since i started pre-clearingI think you might be exaggerating a tiny bit... at the moment it runs for 19h and is in the post-read @25% for both discs if the post-read speed remains the same, i will be rdy around 2 o'clock tonight, running over 30 hours for each disc That is about average for 2TB disks. the very best invention within unRAID is the ability to get status reports for every piece of information by mail. thats the only light at the tunnel of preclearing discs. Yes, the e-mail feature in the preclear script can be handy if you've got mail configured. Please post at 2... (unless it is 2 AM... in that case post when you wake up the next morning.) Joe L.

September 17, 201015 yr There were no re-allocated sectors in the pre-report, and it appears as if the smart report did not run on afterwords. I'm still going out dancing... but you might try smartctl -d ata -a /dev/sda Just to be sure there are no re-allocated sectors. Joe L.

It is almost as if it has stopped responding to SMART commands. does the drive respond to an hdparm command? hdparm -i /dev/sda
September 17, 201015 yr Author your answer is here: /dev/sda: HDIO_GET_IDENTITY failed: No message of desired type and preclear_disk.sh -t /dev/sda leads me to: Pre-Clear unRAID Disk ######################################################################## ######################################################################## ./preclear_disk.sh: line 825: [: too many arguments ============================================================================ == == Disk /dev/sda is NOT precleared == ============================================================================ i'm sure i jumpered only 7+8 but well even with advanced format active those drives were at 10MB/s... and my email timestamps tell me, that right after 75% .. maybe at 76-78% post-read status report, it instantly send the "PASSED" mail sdb somehow is still running and going to be precleared.

(well ihave had running both discs on preclearing script at the same time. maybe its so slow thats why) and sda: is there any way to recue my sda? maybe flashing the drive?
September 18, 201015 yr Author @sda: well i thought this drive would be dead or at least in a near death experience i plugged it into my windows 7 computer and was able to create a partition, as well as copying to this drive with up to 100MB/sec i really have no idea how to put all those thoughts together since i was close to go on the way to my post station to send this 1 drive back. windows is checking the drive right now. maybe it finds anything
September 19, 201015 yr Author this REALLY freaks me out i have had formatted the disc to NTFS again and checked it with win7 as said above. now i plugged it back in the unRAID server and did the same comands as you suggested. everything goes way better than before.. i made sure that "sda" is the same disc as before and got those results: hdparm -i /dev/sda root@Tower:/boot# hdparm -i /dev/sda /dev/sda: Model=WDC WD20EARS-00J2GB0 , FwRev=80.00A80, SerialNo= WD-WCAYY0217525 Config={ HardSect NotMFM HdSw>15uSec SpinMotCtl Fixed DTR>5Mbs FmtGapReq } RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=50 BuffType=unknown, BuffSize=0kB, MaxMultSect=16, MultSect=?16?

I dont know if there is anything wrong within the report but at least this time it responds. i will re-preclear this disc now and report later
September 19, 201015 yr Author well, i don't trust the preclear script anymore. preclear #1 was done in 3,5 hours. msg: preclear successful (it somehow skipped somewhere in the preread and jumped right to the end) in unRAID the "Start" button took its time but never worked. preclear #2 took me 30 hours msg: preclear successful (it jumped instantly to the end from 75% post-read) smartctl said "error, no smart commands possible" or something like that. "preclear_disk -t" said "nope, not precleared" preclear #3 canceled with 92% write test. telnet putty never refreshed the values since then. - preclear_disk.sh -t said "ya, works. disk IS precleared" - smartctl check said "yes, works" (althougth many stuff in the log said "unknown", like i posted above) now i plugged it into my raid array start button worked. format button worked, too (within a few seconds) but the problem (which is the reason why i started all this), STILL REMAINS so maybe someone can tell me, that it should be fine, if i use midnight commander and start to use the copy function to copy something from /mnt/disc/sda to /mnt/disc/sda with only ~9MB/sec. at this moment i hardly can believe, that the discs are that slow. when i used them in windows, everything seemed normal. my guess is: since the midnight commander and the copy paths are somehow linked/mounted through the USB, the speed is slowed down when i use this kind of copy from sda to sda right now i wait until the parity check is done and will do a performance check with unMenu.
September 19, 201015 yr Author is there any way to make sure to copy files from SDA to SDA directly? i really need to know the current drive speed since my router is still 100mbit. thats why for now everything is around 10MB/sec.. i googled how the linux shell works and found out, linux always uses the same file tree for every device. i guess this actually IS /mnt/disk1

There is no faster way. It is not going on the LAN. Something else must be slowing your server down... Please post a syslog. then we can try some tests directly to/from a specific disk. Joe L.
September 19, 201015 yr Author at the moment the parity check is running. unMenu: bwm-ng bwm-ng v0.6 (refresh 1s); input: disk IO Device Read Write Total sda: 34003.97 KB/s 0.00 KB/s 34003.97 KB/s sdb: 33805.55 KB/s 0.00 KB/s 33805.55 KB/s total: 67809.52 KB/s 0.00 KB/s 67809.52 KB/s are those usual values for parity checks? when doing one of the preclear_disk.sh calls, i always have had around 105-110 MB/s in pre- and post-read and writing zeros was around 92-85MB /s. this is what sounds normal to me. but when using MC, it wont faster than 10MB/s
