I put my unRaid in a new case, and when I brought it up, I mixed up two drives, one of them being the parity drive.  I brought it online, and then realized what I had done and stopped it, but it was .1% done rebuilding the parity drive (which was supposed to be a data drive).  Did I lose all the data on that drive, or will it come up and have only lost a little data, or is there some way to salvage what was on it? - Jeff

If you are using all the same drives, AND, if the parity disk was "valid" before you moved the disks to the new case, then you should be ok.  ("valid" means that before you moved the disks to the new case, you had all green 'leds' on the Main page).

 

If this is the case, then just connect disks as they should be & Start array.

 

If you want to check the suspect data drive BEFORE starting the array, go to the Devices page and make a note of which linux device identifier is assigned to that disk; it will be something like "/dev/hdb" or "/dev/sdc", etc.

 

Then in a telnet window, type this (assume device is "/dev/sdc"):

 

mkdir /x    [make a temporary mount point]

mount /dev/sdc1 /x  [note we appended a '1' to the device identifer]

 

This will take a couple seconds & if no error messages are produced then you disk is probably ok.  type 'umount /x' to un-mount it.

 

If it produces errors, you can try this:

 

reiserfsck --fix-fixable /dev/sdc1  [answer 'Yes' to prompt]

 

This will do a file system check & fix if itan.

Thanks, I will give that a try.

You were right, it was OK.  Thanks for you time and for the great product.
