Drive failure

[MvL]

Hi,

 

It's a said day today.., my cat died and one of my drives died.

 

I want to ask how to proceed. I have a falling 3tb drive (it's not spinning). I want to replace this drive with a 2tb model. At the moment I have no parity drive installed in this machine so the data is lost but i have a backup from all important stuff. Can i remove the drive and replace the drive?

[JonathanM]

Sorry to hear about your very bad day.  :'( Since you have no parity drive, you can just pull the 3TB and put in the 2TB, and tell unraid to forget about your old drive assignments and assign the current drives in whatever logical slot you wish. The procedure for a new config varies according to the version of unraid you are running.

 

Just be very sure you don't assign a drive with data to the parity slot, or you will lose the data on that one as well.

 

At least you have backups. 

[MvL]

indeed i'm glad i've backed up most important stuff. Thanks for explanation.

I've did some testing on the drive that failed. I thought it was not spinning anymore but that isn't true. I was mistaken.

It's passing the test but it dropped out of the array two times. What do you people think of this drive? Should I sent it back. It still in it's warranty period.

[johnodon]

Try a different SATA cable and/or a different SATA port (if available).

To know what happened and what is wrong, we would need to see the syslog that covered the period where it appeared to fail.  There are a number of things that could have happened, and johnodon's advice will correct some of them.  Also check the drive power cable and all connectors.

 

The drive itself does not appear to have been the problem, but can I assume there were no ATA errors listed?

 

However, the drive does have one alarming number - the Seek Error Rate.  It's currently 39, which is dangerously close to the failure threshold of 30.  For Seagates, it is usually in the 60's, and getting low if its in the 50's.  I would monitor this drive closely.
