attached is the sys log.

I just replaced a g/byte motherboard with a Biostar TA760G M2+

from ths syslog looks like I have atleast 3 discs affected with HPA

 

can I deal with this in one hit or am I going to need to do a sequence of tasks to get this cleared up .

 

 

I am running Unraid 4.5  - want this fixed so I can upgrade to 4.7  and install a larger parity drive.

 

assistance greatfully accepted.

I downloaded the ultimate boot CD, used HDAT2 to remove HPA. However, I'm not sure if removing HPA destroys the filesystem..  I transferred data off to new disks one at a time, removed HPA on the affected drives, then pushed into the array.

Removing the hPA does not delete the file system but to unRAID it will look as if it was replaced with a larger disk.

 

Best bet is to un-assign the disk, start the array with it un-assigned to make it forget the serial number then re-assign it and let it re-construct onto the larger disk.

can the ultimate cd be copied to a flash drive ? I dont have a cd attached to a working pc at the moment -

 

what about the hparm command - ? or is it to complex to remove off 3 drives that way?

The hdparm command works for some, but not for others.  It is by far the easiest, I'd give it a try first.

so if I read my log correctly I have hda's on ata 4,5,6    or discs whos serals end in 0741 ( sdd) , 0770 (sde) , 7793 (sdf)    is that correct?

yes, it looks like you are interpreting it correctly.

You can probably remove the HPA by performing the following on each disk in turn:

Stop the array

un-assign one of the disks with the HPA

type

hdparm -N p1953525168 /dev/sdX

(where sdX = sdd, sde, or sdf as appropriate)

Start the array with the disk un-assigned

Stop the array

Re-assign the disk

Start the array with the disk re-assigned.  Let it reconstruct the contents of the disk onto itself.

Repeat with the next disk.

am doing that now - 1 disc done - 2nd in progress, should also have looked at the main page - the size column also gives a big hint as to which discs are affected - using hdparm - it had fixed both discs so far.

 

 

regarding the hdat2 method - I did find a method to install it on a flash drive - that way the discs dont need to be removed from the case to be fixed. would anyone like me to post details and the utility I used?
