I've been working on this upgrade for a few months now and I can see the light at the end of the tunnel but I have one more problem. After replacing the MB, Supermicro raid card, several PSU's I finally figured out that my problem was an Icy Dock 3-in 2 drive cage with a faulty board (worked fine when I tore the machine apart). Now that I have that replaced everything is running smoothly again but I can't seem to delete some files and I need your advice please.

 

Here is what I think happened. I had a drive that was in the affected cage that was showing up as failing (without knowing at the time that the drive was fine and the cage was failing). I was fearful that I would lose all those movies so I grabbed a brand new 3 TB drive that I just bought and put it in without preclearing it. Parity rebuilt the drive but in the process several files became corrupted. All in all I only lost about a dozen movies and a few backdrop pictures so it wasn't a complete train wreck. I was able to copy all the remaining movies and files onto other drives but I can't seem to delete them from the 3TB. I keep getting "access denied - read only" error messages no matter what I do. I have tried at least a dozen different processes that I found on the net, including putty, telnet, midnight commander, the New Permissions Utility in unRAID, etc. and I keep getting "access denied".

 

What I would like to do now is just "clear" that drive and wipe out the share that was on it, basically just start over like it was never there. My main concern now is that if I do that...

 

A) I won't be able to start the array with the missing disk, and/or...

B) Parity will immediately try to rebuild that disk with information I no longer need (because all the movies have been copied to other disks already).

 

Could somebody advise me on what you would do in this situation, and walk me through what I should expect to happen as I do it?

 

Thank You

Try to delete the files with midnight commander.

The chances ae that there is some file system level corruption on the disk.  The normal recovery would be to run the appropriate repair tool (reiserfsck for reiserfs, xfs_repair for xfs) if it was important you recovered data.

 

However in this case you indicate that the data on that drive is not important?  In that cae I would make a note of the current disk assignments (screen shot of the Main tab) and then use the New Config option from the Utils tab.  This will reset the array as if it had no disks assigned.

 

At this point you want to force unRAID to treat the problem disk as a new one ignoring any data already on it, and the easiest way is to use the gparted utility from a console/telnet session to delete the existing partition on the drive.  Make sure you write out the changes.  The screen shot of the Main ta mentioned above will tell you exactly what /dev/sd? device to use for this drive when using gparted.  If you are not confident with using gparted and would prefer a GUI baed method then you could temporarily put the drive in a Windows machine and use Disk Manager to delete the partition.

 

Now re-assign the drives as you want them.  When you have just done a New Config unRAID will recognise any drives that already have data on them and when you re-add them to the array the data will be left intact.

 

Thanks a lot for the info, sorry about the delay getting back (I didn't mean to be rude, just busy @ work).

Not at all, it has all been moved to different drives

 

In that cae I would make a note of the current disk assignments (screen shot of the Main tab) and then use the New Config option from the Utils tab.  This will reset the array as if it had no disks assigned.

So this is basically like starting over? I would just remake my current shares and I would be good to go?

If I did the above New Config option couldn't I just preclear the drive at this point so I could use it in another slot?

 

Now re-assign the drives as you want them.  When you have just done a New Config unRAID will recognise any drives that already have data on them and when you re-add them to the array the data will be left intact.

My main objective is to go forward with the data I have and reconfigure parity so that when I put a new drive in that slot the current parity wont try to rebuild it.
