I own a MBLD 4TB and recent I found one of it’s hard drive has bad block, so I want to replace the hard drive to a larger size.
To ensure the new disks were compatible, I read a lot of articles especially the debrick guide from @nfodiz
As my MBLD is not so bad, not bricked, so I find there is a easier way to replace the hard drives:
- Backup your data
- Prepare the new hard drivers, I purchased two 4T Red disk
- Shutdown the MBLD, replace one disk with the 4T one
- Reboot MBLD, it will rebuild the raid to new disk, although it can only recognize 2T capacity, we will fix it later
- Shutdown MBLD and replace another disk, reboot and waiting for raid rebuild
- Now you have the new disks ready, but the device still show only 4T capacity in total
- Enable ssh from /UI/ssh
- SSH login, and execute parted (an linux tool which can modify the partition table)
- In the parted prompt, you should see something like below:
(parted) print list
Model: ATA WDC WD40EFRX-68W (scsi)
Disk /dev/sda: 4001GB
Sector size (logical/physical): 512B/4096B
Partition Table: gpt
Number Start End Size File system Name Flags
3 15.7MB 528MB 513MB linux-swap(v1) primary raid
1 528MB 2576MB 2048MB ext3 primary raid
2 2576MB 4624MB 2048MB ext3 primary raid
4 4624MB 2000GB 1996GB primary raid
Model: ATA WDC WD40EFRX-68W (scsi)
Disk /dev/sdb: 4001GB
Sector size (logical/physical): 512B/4096B
Partition Table: gpt
Number Start End Size File system Name Flags
3 15.7MB 528MB 513MB linux-swap(v1) primary raid

2 2576MB 4624MB 2048MB ext3 primary raid
4 4624MB 2000GB 1996GB ext4 primary raid
- Select the first device, and resize the 4th partition (Please make sure you saw the partition table similar, and you know how to find your own data partition)
(parted) select /dev/sda
resize 4 4624M 4001G
-
Ignore the warnings
-
do the same on second device
select /dev/sdb
resize 4 4624M 4001G
- Reboot, the MBLD will show the Red light
- Login to Web UI, and do a Full Factory Rebuild
- Everything goes well after it’s done
