Expanding disk group & disk crashed!

Recommended Posts

Greetings, i have 6 WD 3TB RED and i added 2 more to my system and when i was expanding the disk group it showed me that one of the new ones crashed

My version is DSM 5.2-5565

 

What should i do?

Can i stop the operation and check the crashed HDD to my desktop to check for bad sectors etc?

Should i allow it to end and then do the replacement with a new one?

If i leave it to expand the disk and one more crashes i will lose all my data (SHR2)?

 

Thank you in advance for your help!

hmm... Hybrid mode is messy.

 

with that many HDDs, I'd have gone RAID10, then it would have been safe to do a repair without worry of losing data.

 

is the Crashed disk, from the new ones that you added, or it is from the existing disk in the hybrid RAID ?

The crashed one is from the new ones.

 

The log wrote errors like that "SYSTEM: Write error at internal disk [4] sector 121006024." so i guess either the sata cable is bad (cause i used an old one) or the HDD has indeed bad sectors.

 

Now the expanding is at 50% with no other errors...

if it's from the new HDD, then it's safe to hit the Repair button.

 

alternatively, as you mentioned, just take it out, have it scanned on a Linux / Windows machine to see if it's an actual bad sector on the new HDD, then send it in for RMA if confirmed it's a bad drive.

I will hit the repair when the expanding is done (not its at 80%) and then i will take out the disk to check it at windows desktop with WD diagnostics.

 

Thankfully the shared folder of the xpenology is visible at my desktop so i can do a minor backup of some important stuff i have there.

So the expanding finished, the volume is of course downgraded.

I inserted the bad drive at my desktop and wd diagnostics found some bad sectors that repaired them...so what should i do next? Re-insert it to xpenology and repair the volume or replace it with a new one?

Definitely replace it, since that is a permanent issue on that disk, it will reappear again if you keep it.

since you are still under warranty, might as well change it and get a new replacement.

Yes, it was a kinda "false alarm", i re-run the full scan of diagnostics and had disk failed error because of many bad sectors... so i will replace it with a new one (and its only 7 days old)!

So i inserted a new one and the repair finished just fine!

 

Now I can safely expand the allocate size of volume to max without losing data, right?
