A 250GB drive in my array died, I'm trying to replace it with a 500GB drive. I'm following the procedure here: http://lime-technology.com/wiki/index.php?title=FAQ#How_do_I_replace_a_hard_disk.3F and running Unraid Server Pro 4.5-final.

 

I replaced the 250 with the 500 on the "Devices" page--everything looks fine there. I've attached a screenshot of the main unraid page. There is an orange circle next to disk5--this is the disk I replaced so I'm guessing this is normal. There's also an orange circle next to the parity drive--is this normal?

 

When I check the "I'm sure I want to do this" and click "Start"....all of the drive size briefly goes to "Unformatted" as it tries to start. Then, a few seconds later, it goes back to the "Stopped" and "Upgrading parity."

 

Not sure what I should do? I'm assuming it's not actually "upgrading parity" as there isn't any other sign of this on the main page...but this may be some new feature that I'm not aware of?

 

Any help would be awesome. Thanks!

So if I remove disk5 (replacement disk) from the devices page the array starts up just fine.. Why won't it start with the disk in place?

Nevermind, I think there is something seriously wrong with the drive that I'm trying to replace it with as well...guessing it won't mount.

So now that I've determined the replacement drive to be bad, I'd rather just remove disk5 completely from the array. There was data, however, on disk5 that I definitely don't want to lose.

 

If I remove the drive from the "devices" page and do a "Restore"...will this cause me to lose all of the data that was on disk5? I'm assuming it just rebuilds parity from the current drives?

 

So...to maintain the data from disk5 and remove the disk completely from the array, do I need to manually copy all of the data (by starting the array without disk5), and then do a restore when I'm done with that?

Do NOT press restore or you will lose all the data on the failed drive, until AFTER you have copied all the data off of the "simulated" failed drive.

 

Then, as you said, you can un-assign the "failed" drive, press "restore" and then "Start" the array to have it build a parity disk based on the remaining drives.

Thanks for the heads up--I'll do this now.

Please post a syslog.

 

There is something very odd about your screen-print.  It should not have said upgrading "parity"  as it was not being upgraded at all.  The syslog should provide some clues.

 

As far as replacing the drive, unless it was using a different "port" on the disk controller (or a different controller) you would not normally need to even assign the replacement disk to the old slot in the array.  Normally unRAID will simply show you the old disk's morel/serial, and the new model/serial number and wait for you to confirm the replacement on the main page.  You would then check the "I'm sure button, and press "Start" to begin the rebuilding onto the replacement drive.   

 

Did you perhaps move parity to a different cable, or different port when you made the original disk replacement?  (I' still trying to figure out why it thinks parity is being upgraded)
