RAID DP Disk Failure

I know that RAID_DP allows 2 disk failure.

Let's say there's already a disk with double parity failed, and theretically, it allows another disk to fail, but if another disk fails, will the system shut itself down automatically after 24 hours for its own data-protection?

Re: RAID DP Disk Failure

It will not.

An automatic RAID rebuild will start as soon as the first drive fails using one of the hot-spare disks.

Re: RAID DP Disk Failure

Assuming there are spares available.  If the system is unable to rebuild, then yes, it will shut itself down in 24 hours, though this can be altered with the raid.timeout option.

Re: RAID DP Disk Failure

True. A system with no spares is rather an uncommon view though.

Re: RAID DP Disk Failure

Assuming that it's the controller shut down the raid group, so how to restart it after its shutdown?

Re: RAID DP Disk Failure

once the disks are replaced , have to boot up the filers.

Re: RAID DP Disk Failure

But there is no spare any more and warranty has expired.

I just want to know when one of the controllers shutdown the raid group, how to restart it?

Re: RAID DP Disk Failure

pull the failed disks out & start the filer.

have to change the raid.timeout option after starting.

Re: RAID DP Disk Failure

Can the filer controller be remotely started or do I have to physically be there to push the button?

Re: RAID DP Disk Failure

It can be started from the loader prompt I believe.
