Hi, I had a drive that failed and I tried to recover from the parity as much as possible, I want to put the salvaged files back in my array on their own dedicated disk for now until I am able to do a physical recovery and can swap it out completely at that time, but I want to make the disk read only so nothing is modified on the disk (it has a few shared directories that span across multiple disks so if anything is added they will be added to the other disks).

 

I don't see any way to make the entire disk read only, am I missing something or do I have to do it through the shares (and exclude the disk on the share directories on the disk)?  I just want to make sure users, Dockers, etc. don't write anything to the disk.

 

Thanks,
Kevin

There's no GUI option to make an array disk read-only, you can exclude it from the shares to prevent new data being written to it.

Ok I will exclude the disk for sure under each share, I just wasn't sure if I have some appdata files on the drive that I just want to be read only if there's going to be an issue with Dockers reading them and to assure they won't write to the disk?

You can use the GUI to see where the appdata is.

I know, I just want to ensure that the files on that disk can only be read and not written to (or any new ones added).  Also is there a way to globally exclude drive sharing on all shares without having to individually go into each and exclude it?  I haven't put it online yet.

No, there isn't.

 

Don't understand what you're trying to do though. If a disk fails then you replace it and it gets rebuilt from parity, the old one shouldn't be in the array anymore and if you wanted to do recovery work on it for some reason (shouldn't be needed) you should do it on another machine.  

I had multiple drives fail at once, I was only able to salvage part of the data on one of the disks from the parity so I want to put the partial copy of that data back in my array for read only access so it can be referenced temporarily until I can have a hardware recovery hopefully done then I can swap the disk out.  I don't want any modifications made to any of the data on that disk and written to a different disk in the meantime.  Only the temporary disk would be read only, the rest of the disks are read/write.

Yes, that was what I was suggesting you do: Settings -> Global Share Settings.

That doesn't work the way I want it to, it does not display files that are on the excluded disk under the shares.  I still want the files visible, I just want them read only along with the disk.

Then you need to exclude it from all shares that use that disk.
