(SOLVED) How to reformat hdd already in array?

Featured Replies

Hi,

 

Yesterday i had a hang up of unraid during a format, i realize now that the drive that was hung during format may not have completed correctly.

 

Here's what happened

I issued format

Unraid hung

I started unraid and issued another format, the format completed.

 

Now the drive seems to be healthy but when looking at the used on the particular drive (10) it has more used space then other drives in the same category that didn't lock up during initial format (see screenshot below of disk 10, there's no data on disk 8,9 or 10 but during format of 10 unraid hung).

I want to issue another format to disk 10 to make sure it is working correctly before i write any data to it, how can i do that?

If you click on the blue "Disk 10" text you'll open that disk's Settings page. One of the items is "File system type". The easiest way to format the disk is to change it to something else and then change it back again. To change it you'll need to stop the array first. When you restart the array it will be formatted, with appropriate warnings. So, stop, change file system type, start, wait for format, stop, change format type back again, start, wait for format.

 

However, the system shouldn't hang like you described. You may well have some underlying problem that needs fixing.

I know, i am still trying to figure out why it hung, but the only culprit was i added 3 plugins to my arsenal and then the system locked up, i uninstalled these plugins and no problems since, but still not sure. I have logserver enabled now so if it happens again i will at least know whats up.

 

Thanks for the trick on how to trigger unraid to format it.

You're welcome. Post your diagnostics if it happens again and you need help.
