Hello,

 

in this Topic I want to collect several Idea's / Upgardes about UnRaid.

 

So I'd like so see  the following:

- Second Parity Drive, to survive two HD Crashes at a time.

- A Function like SNAP, to mount aditional single Drives, for special needs.

- more DataDrives, 30 would be nice. This is also my No. 1

- like in a nother Topic may a special Aplication Drive. But this could also be done, by something like the SNAP Tool.

- a new / aditional command line script for a save shutdown. Cause the known shutdown script does not know about the SpecialDrive.

 

Specially the aditional DataDrives would be really nice.

 

If You want, call ist a Pro Plus Version.

 

I'd have no problem, if this Upgrade to a Pro Plus would not be free of charge....

I think a lot of this stuff has been brought up before.

 

As far as the extra data drives or second parity, I"m not too fussed either way but I'd like to see it use and extra 2 drives. A lot of us use the norco 4224 cases which allows up to 24 drives.

 

Either 2 extra data drives or the second parity and extra data drive.

You are right, a lot of it has been here before....

 

I do not kow, how difficult it would be to add more DataDrives.

 

I'm using a LinaLi PC-343B Case, that can hold 6 5>3 Cages.

Aditional 6 internal Drives.

So I could use up to 36 Drives.

 

This made me think of the 30 Data Drives , one Cache, two Parity, lets say 1 HotSpare and two for special use....

What, from my point of view, would also be nice would be a Raid 1 Mode/Option for the Parity Drive(s).

 

The Parity Drive is the one, with the most Traffic, fom this point this would make sens to me.

But it is the least important drive in actuality.  You can lose it and not lose any data.

Agree, you can loose parity without loosing any data, RAID1 on a parity drive is counterproductive.

The performance hit would make unRAID very slow.

 

Also the parity drive is not the most used drive, it's only the most used drive when you are populating the array. Once it's populated with your movies and music, only updates are written to the parity drive.

 

What would be better is RAID1 on cache. Anything placed on cache has a possibility to loss for a maximum period of about 24 hours.

The possibility of loss is worse if you use it as an application drive.

 

For those who say they would spend more, The answer is an ARC-1200

What can be done is a two fold aid to unRAID.

 

Using a SAFE33 arrangement and a pair of sizable drives, you can have a RAID0 Parity and RAID1 cache.

 

This provides a nice performance boost for writes to the array and a safe area for cache and apps.

 

I do this and have had great success with it. 

 

Plus you can have that today instead of waiting for limetech to develop it.

 

There has been talk of a possible second parity to handle a 2 drive failure for a long time.

It's going to be a long time before anything happens with that.

5.x has been in beta for 14 revisions for over a year, There's still a 15th pending.

 

As far as adding more drives, I believe this is coming up.

There was mention of adding slots in a prior beta announcement.

I believe it's an additional 2 drives.

Why not just use SNAP?

Why only two aditional Drives, is there a 'special' reason?

For me +10 Drives, to get 30 Data Drives would be perfect.

I have seen a Case for 50 Drives, so why not?

 

@queeg

Does not work with 5.beta14

Moved to 5.x and it stopped working....

Just because you have seen it does not mean it is a good thing to go with.  The reason for the 24 is becuase the vast majority of people that are looking for high drive density are going to be looking at the norco 4224 and 4220.  The 4224 has 24 drive slots in it, so 24 makes a nice logical number to go with.  That way you can have 24 hot swap data drives and mount the parity(s) and cache internally.

Ok,

I also know a lot of people that do not want a Rack Case in there Home.

Also this Case is not really easy to get here.

So some are using the LianLi Cube Case, and there You cat put 6 5in3 Cages in.

Also it comes with a aditional internal 3 Drive support.

So You get a nice cube.

 

Would it be that complicated to add more Drives?

 

Also I do not see a reason, why any case should be a reason to limit the number of Drives.

 

BTW, why isn't it a good reason go with a Case that supports more than the often used case for 24 Drives?

Probably not, but it is one more thing that has to be tested and verified.

There is a point you get to where adding more drives without adding a second parity drive gets risky.  I would really not want to go over the 24 data drive mark without having the option to add a second parity drive.

If the Parity Drive fails and also a second one, I always have to create a new array and fill it up.

 

So the difference between 24 and 30 is only, that I have to copy the Stuff of max. 6 more Drives to the Array.

 

"Probably not, but it is one more thing that has to be tested and verified."

 

Again sorry, but the testing has always to be done, not only 'especially' for the aditional 6 Drives.

Since I'm not the author/owner of the software I cannot answer why it's only going to be 24 drives instead of 30.

In the past drive count has gone up slowly.

Since a popular norco case supports 24 drives, it makes sense to increase the drive count to 24.

If you want 30 drives, Then contact limetech directly and lobby for the increase in drive count.

I think the only reason it's held back is the coding and testing.

 

Reliability of drive and data is really the end users responsibility.

Coding and test it is the author/programmer's responsibility.

So you need to build a machine with 30 drives in order to test it out, Then factor in the amount of time it takes to do all the testing.

Probably a big factor in the slow increase in drive count.
