Server gets suddenly unreachable

[skank]

After years of happy use, i now have issues.

It seems my server suddenly becomes unreachable, then without doing anything back reachble and this in loop

 

Addons showing bad behaviour:

Sabnzb web ui is reachable then after i dunno 5 minutes it says connection is broken

Emby server -> when using client, it suddenly says the server (on unraid) isnt reachable and web socket connections are lost, i dunno why, then it just restores

 

I added log

I hope you guys can help

Enable the syslog server and post that after a crash.

Hi i did

But then i found out disc 1 has smart errors

See log

 

This might be the issue cause the file was on that disk

 

Is the disk dead? Should i replace?

If its dead and has to be replaced.

What should i do?

I have a one parity disk + 7 data disk array

The parity is 6 tb

One disk out of the 7 is 6 tb, rest is all 2tb and 3 tb

Disk 1 , the oldest, which is apparently dead now? , is 2 tb

Should i just replace it by a 6 tb

Or should i replace the parity into 8 tb, and then use the old 6 tb parity to replace disk 1 ?

Not the persistent syslog.

It looks pretty dead.

First you need to replace the failed disk, to replace parity all data disks must be good.

[skank]

Oh crap, so i cant buy a 8tb disk...

Cause i first need to swap disk 1, and then i cant use that same disk to swap the parity?

So i'm obligated to buy a 6tb disk? No way i can buy 8 tb now?

[skank]

What would happen if i swap the parity with a 8tb first, and then swap disk one with the old parity?

 

[JorgeB]

You can do the parity swap procedure.

[skank]

Cool thx !

[skank]

I might upgrade my other hardware as well.

I'm gonna buy a new mobo, cpu and ram.

Can i just swap after or before my disks swap?

Or is it linked to my  unraid license?

[JorgeB]

License is tied to the flash drive, you can swap everything else.

[skank]

Cool thx

[skank]

Ok i tried parity swap

Followed this video

 

 

When i enter the 8tb instead of the old parity 6tb

And i change the 2tb defect disk 1 to the old parity 6tb, the disks dont show blue and i cant copy the parity information to the new parity...

 

What now?

 

i can say for disk 1 to "no device" and keep the parity the old 6tb drive and then i can :

Start will disable the missing disk and then bring the array on-line. Install a replacement disk as soon as possible.

 

 

Should i click that?

Do know that the 8tb disk, isnt new either , its an old free nas drive

Is this disk disabled?

How do i know?

I unassigned it and took it out

 

So i should put the 6 tb parity back as parity and at disk 1 leave it blank and say yes to:

"Start will disable the missing disk and then bring the array on-line. Install a replacement disk as soon as possible."

 

?

You must start the array with the disk unassigned, it will then show a red x, it's a requirement for the parity swap to work that the disk is disabled.

Correct

[skank]

Yes perfect ! It's starting to copy parity !

Great, i wasnt sure ...

Thx a lot !

Curious when its done, all is good.
