September 30, 201015 yr Hi, I have a unraid at v4.5 and successfully upgraded my parity to 2tb (WD - black) - following proedure on the site. I wanted then to change my smallest drive (250gb) to a 2tb wdears. I had precleared the 2tb wd ears and jumpered 7-8 (and i thought the results were fine). I think i hit the wrong button - (start and yes i want to ) The wd ears started to get to 300ish errors and the parity drive started to do lots of writes to itself and little or none to the new 2tb drive. I figured things were going badly so i stopped it. I would like to put my 250gb drive back that still has valid data and rebuild the partity drive (i don't think any of the other drives were written to) I think that is he best way forward? If so how should i do it. If not what do you suggest? I should run preclear on the wd ears drive again and see how bad it is. REgards Dave

(instructions in the wiki under troubleshooting) 2. tell us what version of unRAID you are running. 2. attach the result of a smartctl report of the failing drive. smartctl -d ata -a /dev/sdX where sdX = the three letter designation of the disk with the errors
October 1, 201015 yr Author hi, I guess i had inadvertantly started a parity rebuild with by cleared wd ears drive - dickhead! Atleast the data on the 250gb harddrive is intact. 1) unraid version is 4.5.6 2) syslog or recent restart is below (not of the one where i had the drama). You will notice i had network issue which i find works a lot better when cable is properly inserted. 3) smartctl of crook disk is below: Regards Dave smartctl.txt syslog3.txt
October 17, 201015 yr Author Hi, Sorry if i offended above. My reference to dickhead was not implying other people were dickhead's but rather my bone headed self. I would like to rebuild my parity drive on my old 7 disks (which are all unchaged). The current parity drive started to be rebuilt using the precleared 2tb drive rather than the old 250gb drive(with data on it). When i ask unraid to build parity with the 250gb drives it won't do it (i think it wants the 2tb drive inserted). Is there a flag/setting i can change to get it going? I'll do some testing on the 2tb drive to see if it is sick and start again when it is ok/replaced. Cheers Dave
October 17, 201015 yr I think you should just be able to put the old drive back in and rebuild from there. You haven't lost anything except for parity protection. Your old data drive goes back in, you hit sync and hope nothing else craps out in the meantime. Edit: just saw that your system doesn't want to rebuild with the old drive in. What does it do when you put the old drive in? Did you make sure and assign it back on the array on the devices page? I'm not seeing anything bad on your SMART or syslog, but I'm a noob too.
October 17, 201015 yr Is there a flag/setting i can change to get it going? you need to log in on the system console or via telnet as "root" Then type initconfig to set a new initial configuration Respond to its prompt with "Yes" (capital "Y" and lower case "es") The refresh the web-management page. All the drives will have blue indicators and when you start the array parity will be calculated. Joe L.
