I'm having trouble with a ~700GB array I'm trying to connect to a Micron
NetFrame 5200 running FreeBSD 4.0 using an Adaptec 2940U2W. First, dmesg
reports the drive as follows:
da6 at ahc2 bus 0 target 1 lun 0
da6: <RAIDinc. COBRA-2 0223> Fixed Direct Access SCSI-2 device
da6: 80.000MB/s transfers (40.000MHz, offset 31, 16bit), Tagged Queueing Enabled
da6: 667826MB (1367708160 512 byte sectors: 64H 32S/T 12466C)
Note that the size and total number of sectors is correct but the number of
cylinders appears to be truncated.
I can label, newfs, mount, and unmount the drive, but fsck claims the
superblock is bad every time. It claims to fix it, but if fsck is run again
it reports the same problem. Below is a transcript of the session showing the
disklabel, newfs, and fsck's. Is there a problem with the configuration or
does FreeBSD have trouble with this size drive?
