Just upgrade from 4.7 to 5.0 rc12a.  syslog attached.  I have not started the array yet because a disk1 shows red ball and says "wrong" below it. 

 

My drive in the drop down box shows as:

WDC_WD1001FALS-40U9B0_WD-WMATV3946610 (sdb) 976761496

 

Next line says "wrong" and shows:

WDC_WD1001FALS-4_WD-WMATV3946610

 

What should I do from here?

thanks.

According to your syslog, disk1 has an HPA

 

May 31 19:32:51 Tower kernel: ata2.00: HPA detected: current 1953523055, native 1953525168

May 31 19:32:51 Tower kernel: ata2.00: ATA-8: WDC WD1001FALS-40U9B0, 20.04F20, max UDMA/133

May 31 19:32:51 Tower kernel: ata2.00: 1953523055 sectors, multi 16: LBA48 NCQ (depth 31/32), AA

 

You can either go back t 4.7, remove the HPA and re-construct the disk, then upgrade t 5.0 once more

OR

You can go into "Utils->New Configuration" and set a new disk configuration (which immediately invalidates parity) and then start the array which will re-calculate parity on the new disk (it is being detected as a new size under 5.0 because of the HPA)

OR

You can un-assign disk1, start the array with it un-assigned, remove the HPA using either hdparm or one of the third party disk utilities, then stop the array once more, re-assign disk1, and let unRAID re-construct the contents of disk1 onto the existing disk1.
