Advise needed for cache / unassigned devises


Recommended Posts

Unraid version:  6.11.5

 

I recently added more storage drives and swapped the parity, while server was down I decided to add two 1tb ssds to create a redundant cache and move my "appdata" to the cache and then another 1tb drive to replace the old 500gb cache drive I was using as a download/temp directory.

 

My question is how do I change the single 500gb cache to two 1tb ssds in pool devices and make them redundant, and then what is the best method of adding the third 1tb ssd to the server for my temp/download area? should I use unassigned devices for the download/temp drive or add it as a single pool device. Also once the three ssds are in place how do I move my "appdata" to the cache and have my dockers pull the data from there instead of disk1. last and not least would I be able to mount the old cache/download/temp drive in unassigned devices and copy/ move the data on the old drive to the new download/temp ssd?

 

Sorry if any of this is confusing if needed I will try to clarify better on request

I have already installed the three new data drives,swapped one with the parity to increase parity size, and added three ssds (two for a redundant cache one for download/temp files).

 

If I remove the 500gb cache drive can it be mounted in unassigned devices without formating so I can move the data on the drive.

They are physically installed in the server, but have not been added to unraid as of yet. I would like to replace the original 1x 500gb hdd used as cache with 2x 1tb ssds in a raid 1 setup for some data redundancy. Can I increase the original cache pool to two devices then replace the original 500gb hdd with an ssd. Then add the second ssd in slot two and configure for raid one or would it be easier to delete the original pool and recreate. I do want to hopefully mount the 500gb in unassigned devices and move the data on that drive.

 

Then my question is how do I then move "appdata" to the new 2x1tb ssd cache, and do I need to update my dockers and anything else?

 

After that has been resolved I need to mount a third 1x 1tb ssd I have installed either as a cache pool or unassigned devices to create a download/ temp drive and then mount the old cache drive hopefully in unassigned devices? And move the old data to the new download / temp drive.

 

Btw is their any reason to use unassigned devices vs creating a single drive under pool devices for the download / temp drive.

 

I can get a screen shot later, not near my home atm.

you can just add the new devices and remove the other one, or add one and replace the other.

You can use the mover to move it to the array, then move back to new pool, docker service must be disabled for that.

Sorry for the late reply, anyway I think I was successful at changing the cache and I think I set it up as raid 1. I also created a second pool labeled download for the single 1tb ssd as the download/temp drive, and then mounted the old cache/download hdd in unassigned devices so I can pull the data from it later.

 

Never used the mover before, how do I use it to move appdata from disk 1 to cache ,and is there a way to setup an automatic scheduled backup of appdata to a drive in the array? Also I am assuming I will need to update my docker links to the new cache and download pools?

 

Thank you  for the assistance you have given btw.

Disable docker service, go to shares, click on appdata and assuming you're still on v6.11 set it to cache=prefer and the cache pool=cache, then run the mover, once done set it to cache=only on that same pool, and if you are using /mnt/user paths for your container no need to change them.

Currently in the process of backing up "appdata" as a precaution, but while it is in process I tried to look into your directions and my shares screen will only let me see what is on the drives unless I misunderstood you.

 

Edit: I only have disk shares , is that the reason I may not be seeing it?

 

Also thank you kumper33 for the link.

Sorry, not quite sure what you mean, but if you click on a share you can change the use cache setting.

I only have disk shares setup, appdata would be under shares if I had user shares enabled.

 

Disk shares seem to only allow view of directory structure and enable or disable share access.

Ok, so just cooy or move the appdata directory or restore a backup to the cache drive. Then the only paths that may need editing are under docker settings to point to docker appdata location, and if needed individual docker links updated? Is there anyplace else i would have to change disk1/user/appdata to cache/user/appdata in unraid?

 

Also apparently there is a filemanager plugin would this be an easier method of moving files and directores between drives vs putty and command line? Shit i may need to look up the copy and move lines again been so long since I have used them 🤣.

 

 

Also per one of your previous replies, i am still on 6.11 just upgraded to it a couple weeks ago when starting the server overhaul and may wait awhile before trying 6.12 for bugs to get worked out and dockers updated.
