Unassigned Discs - why?? :-(

[troymeredith]

Disc issues - again!! My HDDs range from approx 4 to 18 months old and two of them are now unassigned on my microserver.

 

The last time this happened, the issue was power-related, and I checked the cabling (disconnected then reconnected) until I got a positive result.

 

I've done the same thing now, but to no avail.

 

Is more checking of cables required, am I impatient by posting this, or is there something wrong with my discs?

 

I have attached a diag in the hope that someone can immediately spot the problem and offer some guidance.

 

TIA

Array is in a strange state, you'll need to provide more info, like:

Was there a parity 1 disk? Is it missing or you were only using parity2?

Both parity2 and disk are assigned as new disks, do you know for sure which disk was which?

 

[troymeredith]

using parity 1, never was a parity 2 disc

[JorgeB]

Then why did you assign it as parity2?

 

Also do you know for sure (by the serial numbers) which disk was parity and which was disk1?

[troymeredith]

really? unintentional!

 

allow me to check the serial numbers...

Last 4 chars of the 2 discs in question:

 

Parity: EN6T

Disc 1: 4XAC

Not really very important, but your syslog is filling with these:

Apr 14 07:06:03 Tower emhttpd: error: get_key_info, 584: Invalid argument (22): get_message: /boot/config/._Basic.key (-3)

Apple ecosystems seem to drop these annoying ._ files on everything they touch. You should delete that file from your flash after you get everything else fixed.

 

Parity and parity2 are NOT interchangeable.

If you are absolutely sure about those serials do a new config, re-assign all disks and check parity is already valid, then run a parity check, if you're not sure also do a new config but assign all disks as data disks, there should be one unmountable disk, that will be parity.

Additional question - any way to remove the "Parity 2" entry if it's not needed?

When the array is stopped and it is ready to allow disk assignments as in your screenshot, then it will allow you to assign parity2. If nothing is assigned to parity2 then when the array is started parity2 doesn't appear.
