Quick Question

Ok i have just transferred my first 6tb of data over and now am formatting that drive and adding to the array 9hrs for 6tb, can i still use dockers while i am formatting or should i leave them shutdown while the formatting takes places? like SABnzbd

I get conflicting answers from the forum search i did.

Also if i decided in the future to tidy case up and stuff does it matter if the drivers are placed into a different SATA port by mistake etc same with m.2 NVME drive if i decide to move to different slot will this make any difference to the array? corrupt etc

44w-210w power usage ish says pc part picker, i need a ups i hear APC is the way to go i'm from the uk any suggestions, all it needs to do is shutdown unraid properly if a power failure occurs rather not spend over £100 if this can be helped thanks for any help.

Perhaps you could re-phrase the question. Formatting a drive takes few minutes at most, not nine hours and you do the formatting before you copy the data onto it. Are you talking about syncing parity, perhaps?

 

Disks are recognised by their serial numbers so it doesn't matter if they are physically moved to different ports.

i have a 10tb drive parity and 10tb storage drive i transferred over the 6tb to the new 10tb and entered the 6tb into the nas mounted drive started array and it says clearing 5% on bottom the drive still has all the data on it when i put the drive in

 

the old drive came out of a xpenology server

Now I understand what you're asking the answer is yes, you can use your server normally while the disk continues to clear. That didn't used to be the case with earlier versions of unRAID but now it is.

Just thought I would elaborate on this a bit. Clearing the drive is filling the entire drive with zeros. It does this so it can be added to the array without invalidating parity, since zeros have no effect on parity. After it is finished clearing, the disk will be part of the array and unRAID will format it by writing an empty filesystem to it.

 

Many people get themselves in trouble because they have a vague and incorrect idea of the word "format". In every operating system you have ever used, "format" means "write an empty filesystem to this disk". This is actually pretty quick, since it is really just writing a top level directory with no files or folders in it. And, like all writes to a disk in the array, parity is updated. So after formatting a disk in the array, parity agrees that it has an empty filesystem.

makes perfect senses thanks.
