Re: problem on 1TB filesystem RAID 5 3ware

[Jim King]

Which tells me that all of the work in the last year has been 
maintenance related to changes within FreeBSD itself, and not any 
updates for 3Ware functionality, e.g no support for firmware 7.5.x on 
the 7000 series controllers, and no support for the 8000 series controllers.

The author of the twe driver, Michael Smith, confirms he
hasn't worked on the driver for several years now.
Quoting Bruce Campbell <[EMAIL PROTECTED]>:
   

I openned a case with 3ware tech support and they responded:

     

We do not support FreeBSD plus the
current driver for FreeBSD has not been
updated for some time to keep up with
firmware changes. 

Please try linux instead. 
       

So I guess I will try that and see what happens.

Quoting Simon <[EMAIL PROTECTED]>:
     

I have a hard time believing that hardware implementation of
RAID5 would corrupt files over RAID10, perhaps your 3ware
card/its firmware is malfunctioning, but anything is possible.
Well, I'll have to see for myself, I'm about to build RAID5 NAS
using maxtor drives and 7500-8 3ware card.

Tested with RAID 10 instead of RAID 5, success !

RAID 10 arrays tested:  6xWD200GB and 8xWD200GB both worked
RAID 5 arrays tested: 6xWD200GB and 4xWD200GB both failed
Note: 3ware lists the WD 200GB disk as "Under Test". (ie 
         

they have not yet
   

given it a "Compatible" rating)

I still have to try an officially approved drive.
