Is there anything in the system logs? I/O errors can be - lots of things. Of course, check your SCSI cable lengths, termination, - etc. Try dumping the big partition by hand. Try cleaning the drive (I - know it's new, but what the hey). And be sure you've sacrificed the - proper color goat.
Since I sent that mesasge I've done some more experimentation. The system logs indicate a SCSI error of the kind I expect from a bad card, bad device, bad or too long a cable. However, other even larger file systems backup with no error so I doubt it is the hardware. I did clean the drive and checked the firmware revision -- JIC. I found some directorys in the failed filesystem have thousands (>10K) of tiny (<400b) files. I am having the software folks archive the data and delete these files. I'll try the test runs again to see if that helps. -- -- Stephen Carville UNIX and Network Administrator Ace Flood USA 310-342-3602 [EMAIL PROTECTED]
