AS-204TE | Increase speed of md1_resync & md1_raid5 | Disk Rebuild RAUD5

[jillman]

Hi All,

I am in the process of upgrading the 4 disks in my AS-204TE (RAID5), however the rebuild is taking around 16 hours per disk.

I can see that the md1_resync & md1_raid5 processes are responsible for rebuilding the indexes, but are only running at 20-30% of the CPU and only at 40-55Mbs on disk.

Is there any way we can increase the resource allocation to these resources to lower the restore time required?

Thank you

Yes. You can refer to the following:

You'll need to use ssh to login to NAS to execute the command.
