rockytt Posted March 6, 2013 Share Posted March 6, 2013 (Running 4.7) Had a couple of smaller disks in my array (500gb) and went to swap one out for a 2tb that I just picked up. Had just run a parity check and it showed no errors, so I pulled the baby drive and popped in the larger one. 30 hours later, parity drive shows a couple thousand errors - so the array was extremely unhappy to say the least. Syslog shows a bunch of "Tower kernel: handle_stripe read error: 21009472/0, count: 1 Mar 5 18:07:48 Tower kernel: md: disk0 read error" lines and SMART shows several "Pre-Fail" and "Old_age" warnings" that I assume are for disk 0 Gotta be the parity drive-yes? Problem is, I can't just pop in the baby drive and replace the parity drive with a new one as I get a "replacement disk is too small" in reference to the 500gb drive. I'm sure there's a command or two that will allow me to do this, but I want to make sure before I hit one of those "I'm sure I want to do this-no really, I'm REALLY sure I want to do this" check boxes... Anyway - thanks for the help on this! Link to comment
rockytt Posted March 6, 2013 Author Share Posted March 6, 2013 One thought I had was to replace the parity drive and put the baby (500gb) drive back in its slot. That would allow parity to be rebuilt on a new disk and then I could go back and swap the baby drive for a 2tb one. No love - 2 red balls (Too many wrong and/or missing disks!) on the two drives Any thoughts? Ideas? I'd swap out both drives at the same time and then just copy the data from the baby drive back onto the array at a later date - but I'd imagine I'd keep getting the same error as above...

trurl Posted March 6, 2013 Share Posted March 6, 2013 (Running 4.7) ...Had just run a parity check and it showed no errors, so I pulled the baby drive and popped in the larger one. 30 hours later, parity drive shows a couple thousand errors - so the array was extremely unhappy to say the least... There are a few steps left out between these 2 sentences. Could you fill in the details a little? Link to comment
rockytt Posted March 6, 2013 Author Share Posted March 6, 2013 There are a few steps left out between these 2 sentences. Could you fill in the details a little? Well, just wanted to update the size of the array by getting rid of the "baby". Removed the 500gb disk and replaced it with a 2tb. Fired up the array and it automatically formatted the drive and began restoring the data. After it "finished" 30 hours later, there were several thousand hours in the syslog-(as listed in the first post) I don't think I left out any steps-as that's all I did. (Just to update this again - popped in a new parity drive and it won't accept that either as it's looking for the old one... Red dot on the new parity drive and orange on the other new drive) Link to comment

rockytt Posted March 7, 2013 Author Share Posted March 7, 2013 And here's a screenshot- Link to comment
dgaschk Posted March 7, 2013 Share Posted March 7, 2013 Do you have the original working disk10? If so, replace the original disk10 and the select Utils->New Config. Post a SMART report for the parity drive. Link to comment
rockytt Posted March 7, 2013 Author Share Posted March 7, 2013 Not to be dense - but I don't see that function (Utils->New Config) on 4.7 But yes, I do have the disk Link to comment
rockytt Posted March 7, 2013 Author Share Posted March 7, 2013 Do you mean run "initconfig" from the command console? Link to comment

Joe L. Posted March 7, 2013 Share Posted March 7, 2013 Do you mean run "initconfig" from the command console? That is the equivalent on the 4.7 release. Link to comment
rockytt Posted March 8, 2013 Author Share Posted March 8, 2013 thanks Joe - I think that did the trick. Popped in the original baby data drive, a new parity drive, reconfigured the array (initconfig) and am happily sitting at 63% with the new Parity-Sync. Once this finishes sometime tonight, I'll upgrade the little data drive, rebuild the data there and be a very happy camper Thanks again! Link to comment
