Pegasus2 R6 Thunderbolt - two drives offline

Hi all,

We are having some issues with our Pegasus2 R6, we noticed one of the drives had a red light about 2 weeks ago and were unsure of what to do so we did the worst - we left it and hoped for the best.

Just today, we noticed the fans were whirring at a high rate (probably due to the UK heatwave), so we took one of the drives out to dust it off and forgot to eject it properly, so it was force ejected.


Now we have two drives with red lights and no access to any of our files. Is there any hope for us?

I'll attach an image of the terminal phydrv as per advice from Frank Bosma on a different thread, but we are concerned as he mentioned that not a lot of time should have elapsed between the drives going down to force them back online. We do not want to lose our files! 

Please help. Thank you!

Beth

Hi Beth,

You should probably contact Frank about this issue since you are in the UK and already in contact with him.

From the look if it it should be possible to bring the storage back online, but it will take a service report to determine the order of events.

Just today, we noticed the fans were whirring at a high rate (probably due to the UK heatwave), so we took one of the drives out to dust it off 

You should never pull a drive from a powered on RAID array, that drive will be marked dead. Before dusting the Pegasus, please power it off and pull the power cord just to be sure.

The proper sequence of events for recovery is to force 1 drive online and start a rebuild on the other. But you need to know the order of events to find out which drive to force online and which to start a rebuild on. A service report is needed for this.

Hi RP,

Sorry for the confusion, we are not in contact with Frank we were just mentioning what he had said in a different thread to another member. 

We know not to pull a drive, it was an accident! Bad play on our part.

We ended up forcing one of the drives online (the one that was accidentally force ejected) and were able to have access to our files again, how do we go about rebuilding the other? 

Let me know how to generate a service report and I will send over.

Thanks for your help,

Beth

Hey Beth,

in the Promise Utility you can click "Subsystem Information' and then the 'Save Service Report' button.
If grayed out you need to unlock the Utility in the bottom left corner.

Kind regards,
Frank

Thanks Beth !

So the order of events was:
- June 17th disk #6 marked offline due to removal
- June 26th disk #5 the same, system ran in critical state for 9 days.

You forced disk #5 back online which is good since it was the last disk that went offline.
(Never force online the 1st disk that failed in case some time passed between the events)

Now you can start a rebuild on disk #6 either via the Array menu or the Background activities section of the Utility.
Again, make sure the Utility is unlocked to show the rebuild option.

Please keep in mind that the report also shows bad sectors found on disks #3, #4 and #6.
It does not seem too serious yet and within error thresholds for HDDs but you might consider creating a backup and replacing the entire set of disks with fresh new (larger) ones.

Hi Frank,

Thank you very much for your help with this! We will spend some time backing up our files and then do the rebuild!

I've also mentioned to my superiors about needed to replace the entire set.

Thanks again!

Have a good one.
