Aldamir Posted August 24, 2022 Share Posted August 24, 2022 Hi, i wanted to add a WD Blue 6TB to my two WD Red Plus (1 Parity, 1 Array) but i always get the message in the title. I've also read that HPA might be the problem, but the new drive has this output: Quote /dev/sdc: SG_IO: bad/missing sense data, sb[]: 70 00 05 00 00 00 00 0a 04 51 40 00 21 04 00 00 80 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 SG_IO: bad/missing sense data, sb[]: 70 00 05 00 00 00 00 0a 04 51 40 01 21 04 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 max sectors = 11721045168/1(1?), HPA setting seems invalid (buggy kernel device driver?) The parity: Quote dev/sde: max sectors = 11721045168/11721045168, HPA is disabled Any ideas - i also wrote the WD Support already. Thanks a lot! Quote Link to comment
JonathanM Posted August 24, 2022 Share Posted August 24, 2022 diagnostics and a brief description of the hardware involved (controller, enclosures, etc) would be helpful. Quote Link to comment
Aldamir Posted August 24, 2022 Author Share Posted August 24, 2022 Up till now i had two 6 TB WD Red Plus (1 parity, 1 array), 1 500 MX SSD as cache and wanted to add the spare 6 TB WD Blue HDD to the array. Right now, my system is on 6.11.0-rc3. Thanks a lot! thonas-diagnostics-20220824-1427.zip Quote Link to comment
JorgeB Posted August 24, 2022 Share Posted August 24, 2022 Mostly likely parity has the partition starting on sector 2048, please post output of: fdisk -l /dev/sdb Quote Link to comment
Aldamir Posted August 24, 2022 Author Share Posted August 24, 2022 It seems like you are right: Disk /dev/sdb: 5.46 TiB, 6001175126016 bytes, 11721045168 sectors Disk model: WDC WD60EFRX-68L Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disklabel type: gpt Disk identifier: 0AEAFFC8-E5D1-443E-9BA9-D02A3F6D44EB Device Start End Sectors Size Type /dev/sdb1 2048 11721045134 11721043087 5.5T Linux filesystem Do you know how to change that? Thanks a lot!! Quote Link to comment
JorgeB Posted August 24, 2022 Share Posted August 24, 2022 Starting some time ago Unraid uses sector 2048 for flash devices, and from that time if a device, disk or SSD, has a partition starting on sector 2048 it will use, it should create a new one for disks, solution it to wipe the disk/delete the partition and re-sync parity, once it's done you can add the new data disk.

Aldamir Posted August 24, 2022 Author Share Posted August 24, 2022 The existing data drive also starts at 2048 - so i wipe the parity disk and then resync? Quote Link to comment
JorgeB Posted August 24, 2022 Share Posted August 24, 2022 1 minute ago, Aldamir said: The existing data drive also starts at 2048 That's fine, no need to change that one, problem is only with parity. Quote Link to comment
Aldamir Posted August 24, 2022 Author Share Posted August 24, 2022 How do i wipe the parity in a way i starts with the first sector? Thanks a lot! Quote Link to comment
JorgeB Posted August 24, 2022 Share Posted August 24, 2022 Easiest way is to remove the partition with the UD plugin, click on the red x, disk must be unassigned and array started without it first. Quote Link to comment
Aldamir Posted August 25, 2022 Author Share Posted August 25, 2022 Thanks for the help! Let's see if this was the solution Quote Link to comment
