Upgraded Drive Capacity - Sync speed really slow after hitting Expand

Post by mavric1988 »

Hi guys,

I was hoping to get some help on this.

I've got an AS-302T. It had 2 x 1Tb WD RED hard drives attached, in RAID 1.

Now, this past weekend I did an upgrade to 2 x 3Tb WD RED hard drives. The initial replacement speeds were pretty good, averaging 110MB/s.

Although after replacing both hard drives and hitting the expand button, there is another sync in progress and the speed will not go above 6MB/s. Sometimes even dropping down to 2MB/s.

The system is not being accessed and I was hoping to find out if it's possible to increase this speed?

Any help would be much appreciated. Thank you

You won't get the speed back up until the drives are synced and the increase capacity job is finished. This could take a while.

You can refer to the following:

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