Here's where I am:

- running Unraid 6.19 with Powerdown- and OpenFiles plugins

- today Iaccessed an Unraid share from a Windows 7 machine in order to delete some files on the NAS

- in the middle of the deletion process, all activity seems to stop and I get an error message that the file-to-be-deleted canot be found.

- I interrupt the deletion process, which after a couple of unsuccessful attempts, succeeds in the end.

- In the Unraid dashboard I see that none of my shares is listed anymore, only the HDDs can be seen.

- I apply the OpenFiles plugin which closes all but 4 PIDs. These can neither be closed by using the respective "Kill" buttons, nor using the command line (all I get is a return to the prompt).

- Using the Powerdown plugin doesn't seem to do anything: I still have the GUI at my disposal and also can still telnet into the NAS; any SMBD access is dead, though..

- From (manifold) past experience I know that if I now stop the array and try a shutdown, I will land in an unclean shutdown: The NAS will at some point become unresponsive and I will have to go for the Big Red Button.

I would very much like to avoid this - the HDDs have had enough wear and tear from (unneccessary) parity checks by now.

Thanks for any help or ideas.

 

 

What format are your data disks? ReiserFS seems to cause these kinds of symptoms on 6.1.x

Yes, it's ReiserFS.

You think I should change the formatting? [me ducks and runs away] 

If so, is there an How-To somewhere?

That's up to you. I've seen some indication that the situation may be better with 6.2 betas, but who knows how long it will be until that gets released, and it may not actually solve anything.

 

The how to is a sticky thread at the top of this forum. In a nutshell, you need to have enough free space to copy the contents of your largest drive, then you can change the format, which puts an empty XFS file system on it, and you copy the files from your next largest drive back to it, change the format on that drive, lather, rinse, repeat.

 

It's a time consuming process, luckily mostly computer time, you just start the next step and walk away for half a day.

Thanks, got it.

Looks like a bit of a nightmare doing this for the first time, but then again, what isn't?

But, to get back to the original question: I will have to do an unclean shutdown with respective parity check first (?).

 

And, under 3. it says: "3 - Start the array, the new XFS disk should show unformatted, all the other disks should be formatted!! (IF NOT, DO NOT PROCEED)"

Do you really mean to take the array on-line, or to just boot the NAS till you can access the GUI? If I am not mistaken, I should be able to move the data around on the HDDs without bringing the array online. That way I also should be able to avoid duplicate files. I would take the array for the first time online again as soon as I am done with the format conversion on all drives and have the data back on them.

Is there a flaw in that logic?

 

Sorry, scratch that - if I did it that way, parity is lost, got that too now.
