Hi,

 

Sorry but I'm quite inexperienced at unraid, and I'm in a bit of a mess...

 

I was having issues with space on my cache SSD drive.

 

So I started messing with the shares that were using the cache, and turned off the cache on some of the shares, Then I got an alert from I think fix common problems saying there were files on the cache that were not copied onto the array. So Not remembering which ones were on or not before,  I turned everything onto "Prefer".

 

Next, the cache drive TOTALLY filled up and mover was stuck, in the log it was constantly saying something like "Cache Drive Full"

 

I could not stop mover from running (I tried "killall rsync" and nothing, I tried "pkill mover" and nothing) So I did a restart from the restart button in the GUI.

 

Unraid booted up and mover was no longer running, so I tried turn the cache off on all the user shares, leaving it only on the system ones that I had not created. But the cache drivve was still full and the system was not running correctly (No VM's no Dockers)

 

I went back into the shares to try and re set teh cache drive, but unraid crashed, and now wont boot.... showing the following screen..

PLEASE HELP!

 

Plug your USB stick to another machine and attached in your next post the 2 zip files in the screenshot (tower-diagnostics-20191209-1038.zip and tower-diagnostics-20191209-1048.zip - they are under \logs folder). Someone on here probably can help have a look.

The booting issue is probably unrelated to what you did to the share cache settings.

 

Also, with regards to cache, you should have set it to "Yes" (EXCEPT for the appdata / docker / vdisk) and run the mover to free up cache space first.

• Yes = store in cache first, mover always moves out of cache into array
• Prefer = always store in cache, unless cache full then mover moves into array, if cache frees up move back onto cache
• Only = no array storage, mover is disabled for the share
• No = no cache storage, mover is disabled for the share

Setting it to No, will not move the files out of your cache because the mover is (effectively) disabled for that share.

"Prefer" is a relatively complex operation that is in the "do it if you know what you are doing" category.

 

If you are not sure, please ask questions and not try to fix it without guidance.

 

Thanks For Your reply,

 

Attached are the 2 files.

 

I will ask in the future!

Cache is completely full, disable VM/docker services (Settings -> Docker and Settings -> VM Manager) before starting the array, move some data off cache, after that restart services and post new diags if still issues.

Thanks so much for replying.

 

OK Array is started this time with the docker and vm's turned off.

 

I'm not sure the best way to copy some data off the cache though, Do I just use MC to copy some large files back to their correct locations? eg from cache drive /mnt/cache/Media/TV Shows to the equivalent place on the array?

 

Or is there a better way?

 

 

 

Set any shares with data on cache you want moved to the array to cache="yes" then run the mover.

After mover completes post new diagnostics.

OK Mover just completed, there is 74gb space on the cache drive now.

Better but still too full.

 

You have a share anonymized as w---------k which is cache-prefer and all on cache. What is your purpose for this share and keeping it on cache?

I've got to say, this is far more clear, concise, and easy to understand than the help text in the GUI.

Both the GUI prompts and the Help text have already been reworked in the 6.8.0 RC series of releases to make the behavior clearer.

Ah, that share is windowsdisk - VM storage

 

I've just set it to yes and running mover.

 

I'm going to upgrade the cache drive soon, is there a good step by step guide for the current release that you can recommend for a complete noob like myself?

 

Is the one on the wiki the right thing to follow?

Thank you all for your help.

 

Since cache is btrfs you can do an online replacement/upgrade, as long as you have an extra port to have both connected at the same time, more info here, see part in bold about single device:

Great thanks for that, I'll post when it's done...

 

Array is all working properly.

 

Right, onto replacing the cache drive. I'm following the guide you linked for replacing a single drive when you do not have a spare 

 

I've turned off dockers and vm's and set appdata, domains and system to "Yes" from "prefer" and run the mover.

However in the cache there is still a folder "System" containing "Docker" and "Libvert" folders.

 

when I rerun mover it leaves them there.

 

In that guide it says the cache drive should be empty.... how do I get it to move the last few files across to the array so I can replace the cache drive?

Did you actually disable the Docker and VM services?   If they are enabled they will lock some files even if you have no actively running VMs or docker containers.

Hi,

 

I turned off the docker and VM manager in the settings and then ran mover after setting the "appdata, domains and system" shares to yes

Do those also already exist on the array?

Yes it does look like they are there on the array...

 

Mover won't replace files so you will have to delete them. Do you actually have any VMs?

 

Dockers are easy to reinstall and I usually just recommend deleting docker image since Previous Apps on the Apps page will get those back just as they were.

yes I've got several vm's

 

If the files on cache are identical to those on the array it should be OK to replace cache. You might try just renaming the files on cache and move again so you will have both copies on the array just in case. Do you know how to work with the files?

Would I do that through the MC command in terminal?

 

I just looked at the files, and there is libvert and docker.img sat on the array disk 4 with a date of 6 July.... so would those be the best to rename?

That would be even better if those are the oldest then they aren't being used and are just in the way of getting those you want to keep moved from cache.
