How long it takes to boot after Replacing 4 HDD in one go

Hi there,

 

I have a RN 104- 4 Bay NAS.

I just pull out 4 x 1 TB HDD and replaced with new 4 x 2TB HDD.

(I did not reformat or do anything on the new HDD. Just open the bag and plug it in)

 

Once power up,  the LED showing "Booting...." and the Act light and Power button are Blinking.

The RAIDar Status showing "System Starting up".

 

This has been going on for  last 2 hours.

Is this normal?

    I haven't done this with an RN104, but it sounds excessive to me.

     

    What disk drives are you using (manufacturer/model number)?

      Seagate BarraCuda 2TB.

       

      Still going on the same after 3 hours+.

      I tried press the power button 3 times.  No respond. Press reset button. No respond.

      By the way, can I just power it off ? Will it damage the 4 new HDD ?

        Unfortunately that's not a good choice - Seagate switched most Barracudas (including the 2 TB models) to use SMR (Shingled Magnetic Recording).  https://www.seagate.com/internal-hard-drives/cmr-smr-list/

         

        SMR doesn't work well with ReadyNAS.  The issue is that the write speeds are extremely variable (due to the nature of SMR).  Seagate (and WD) try to overcome this with a large cache on the disk (and sophisticated caching algorithms), but that doesn't seem to work very well with ZFS and BTRFS file systems.

         

        I suggest exchanging them with the seller for Seagate Ironwolf as the next step. 

         

        You might also check the pricing.  Four 2 TB Ironwolf drives cost about the same as three 4TB Ironwolf drives (current US Amazon pricing).  3x4TB will give you 2 TB more storage, and also an empty slot to make future expansion easier.
