Hi everyone.....
I understand it takes time to initialize a RAID 5 with four 6TB hard drives, but is it possible that it's still at 6.78% in a day?
It's been running since yesterday at noon, and it's not stuck....but this way it'll take two weeks to finish...
Is there anything I can do to speed this up?

Are you creating an array for the first time? After setting up an array with multiple drives, synchronization is a necessary process. This process takes a long time, and the larger the drive capacity, the longer it will take. For a 10TB drive, the estimated synchronization time is approximately 20 hours.

What is the current progress? You can open the terminal and enter the following command to check the synchronization speed: To better assist you, I need to know a few key details:

• What is the specific model of the hard drives? (This is critical: please check the "Model" on the drive label, e.g., WD60EFAX or ST6000VN001)

• During initialization, are you copying large amounts of data to the NAS or running high-load applications?

• Are the drives brand new? Does any drive show warnings or anomalies in the "Drive Status"?

RAID 5 initialization on large 6TB drives can be bottlenecked by low default sync speeds in Linux. You can often speed this up significantly via SSH by increasing the speed_limit_max and speed_limit_min values in /proc/sys/dev/raid/. Increasing the minimum sync speed gives the rebuilding process higher priority.
