How long should RAID-1 rebuild?

[B2BF]

Hi!

I've got Proliant DL 160 G6 with RAID-1 on double of HP SAS 300 GB 15k HDDs. This server doesn't have any jobs right now. So, HDDs are not loaded.

I wonted to test RAID. So, I disconnected one of HDDs and then connected back. Rebuild lasts for about 11 hours already. Is that OK?

Thank you!

Time required for a rebuild

The time required for a rebuild varies, depending on several factors:

• The priority that the rebuild is given over normal I/O operations.Change the priority setting with ACU.

• The amount of I/O activity during the rebuild operation

• The rotational speed of the hard drives

• The brand, model, and age of the drives

• The amount of unused capacity on the drives

Allow approximately 15 minutes per gigabyte for the rebuild process to complete.

System performance is affected during the rebuild, and the system is unprotected against further drive failure until the rebuild has finished.
