fnwc Posted November 12, 2013 Share Posted November 12, 2013 Hi, I recently tried to upgrade a 1.5 TB drive to 4.0 TB drive, but something bad happened when trying to rebuild the replaced disk with existing parity (no drives past the replaced drive showed up on simple features and the unraid main page wouldn't load). I had to reset the server, which then on reboot, caused a parity check with correct to begin. I still have the old disk, however, so I'm pretty sure that my parity is bad, but all of the data disks are 'good'. Right now, I've put the old "good" 1.5 TB drive back in, but it isn't assigned and the slot is red balled because it's expecting the 4 TB drive. I "think" that I need re-assign the old 1.5 TB drive and run the trust my array procedure to get the array to accept the old drive back and rebuild parity based on the existing data. I want to make sure that I don't overwrite my existing data before I've had a chance to correct the parity drive. It also looks like there are changes to the "trust my array" procedure for 5.0. Is there anything specific that I should be careful about? Thanks in advance! Quote Link to comment
vl1969 Posted November 12, 2013 Share Posted November 12, 2013 what you parity drive size? you do know that parity drive MUST be smae or larger than the largest drive in the array? I.E. if you putting in a 4Tdata drive your parity drive MUST BE at least 4T. can be larger but no smaller. Quote Link to comment
fnwc Posted November 12, 2013 Author Share Posted November 12, 2013 My parity drive is 4TB. I'm trying to figure out how I can force unraid to accept a drive and start without having it try to rebuild that drive from parity (since I'm pretty sure parity is invalid right now). Once I have the drive accepted (since the data is still "good" on it), I can rebuild parity correctly with the accepted drive. I'm wondering if the "trust my array" procedure is the correct way to accomplish this. Quote Link to comment
vl1969 Posted November 12, 2013 Share Posted November 12, 2013 weight until some one more experienced chime in, but I think you might need to do New config to make the array accept old drive again. or you can try to un assign the parity drive and the new 4T drive and than add the old 1.5T back than add Parity Back and run parity rebuild. not really sure what the right procedure in the v5.0 Quote Link to comment
dgaschk Posted November 12, 2013 Share Posted November 12, 2013 Record the drive serial numbers and set a New Config (Util->New Config). Then assign the desired drives and rebuild parity. Quote Link to comment
fnwc Posted November 14, 2013 Author Share Posted November 14, 2013 Thanks dgaschk, that did the trick. I just wanted to be extra sure... Quote Link to comment
