HDD failure in your RAID will lead to your RAID downgrade, for your data safety, you need to replace the failed drive with a new one and repair your RAID as soon as possible. To do so, please refer to the instructions below:

1. Please login to TOS webpage, go to TOS Control panel - Storage pool to locate which HDD is missing from the RAID.

2. Pull out the failed HDD at power-on state and insert the new HDD, the capacity of the new HDD should be no less than the capacity of the failed one.

3. Go to TOS Control panel - Storage manager- Storage pool- click Edit, and select "Repair the RAID" from the list and follow the wizard to complete.

Hi,

I recently had a DD down on my F4-220. My storage was RAID1 with 2 Disk of 3 TB each, one of them died (HDD1)

I have followed the above procedure smoothly.,

However I have no indicator of the new disk is currently syncing or repairing. Looking on the forum or internet, it seems usually the process takes several hours and people can tell that it is ongoing (orange led?)

In my case it was a matter if seconds to see the new disk in the RAID1 storage, green status. It looks a little bit too fast and smooth :D

Could you tell if I have a mean to double check everything is fine and over for the disk replacement?

where is this in TOS 5.0?
My system is reporting a raid error after someone pulled a drive by mistake

I dont see the repair raid in 5.0
I hope i haven't lost my data

I'm having the same issue. The edit button is greyed out and not clickable

My RAID had been downgraded but all of the HDD are showing as good. Is this an error in the RAID health reporting?

I have the same issue.
After updating to TOS 5.1.24 the RAID 5 on my F5-422 is degraded.
All disks show as good.
I tried to repair the RAID without success, the "configuring" message has been loading for 4 days.
The disks where inserted firmly and worked fine under TOS 4, as suggested I tried to shut the NAS down and replug the disks.
The RAID is still degraded. I launched an other repair, the "configuring" message is currently showing.
