sluggathor Posted March 31, 2022 Share Posted March 31, 2022 (edited) hi i shucked a wd elements 8tb into my array and now i am getting the error that the parity drive hast to be the biggest. my current setup is: data: 6 disk (4-8tb wd reds) parity: 1 disk (8tb wd red) i want to add the shucked drive as a data disk but get the error about parity not being the biggest disk. sector counts on the disks are identical what gives? EDIT: nvm the partition on the shucked drive is slightly smaller than the parity ( 7.814.025.540 vs 7.814.026.532) jarvis-diagnostics-20220331-1144.zip Edited March 31, 2022 by sluggathor added diagnostics and findings Quote Link to comment
Solution JorgeB Posted March 31, 2022 Solution Share Posted March 31, 2022 Likely the remaining disks are partitioned on sector 2048, instead of Unraid default sector 64. You can check with fdisk -l /dev/sdX Quote Link to comment
sluggathor Posted March 31, 2022 Author Share Posted March 31, 2022 (edited) yes you are correct, which is still a strange thing because i've created and formatted the drives using unraid. why would it put the partitions down inconsistently?

This usually happens when the drives already have a partition starting on sector 2048, Unraid will format the drive but use the existing partition, since that starting sector is now valid for SSDs, it should never happen with a new or completely wiped disk.

sluggathor Posted April 1, 2022 Author Share Posted April 1, 2022 i see. the drives were carried over from another nas setup - i had unraid format them. should i use pre-clear next time or does deleting the old partition before formatting them next time? Quote Link to comment
JorgeB Posted April 1, 2022 Share Posted April 1, 2022 Deleting the old partition(s) is enough. Quote Link to comment
