Description Piotr Kucharski 2005-03-26 12:10:02 UTC 
newfs on 2.6TB gbde disk fails, while newfs on the same 2.6TB disk finishes fine

How-To-Repeat: Given the disk (from Simbolo Proware ide-to-scsi array):
da2: <SB-3160S Volume Set # 00 R001> Fixed Direct Access SCSI-3 device 
da2: 160.000MB/s transfers (80.000MHz, offset 62, 16bit), Tagged Queueing Enabled
da2: 2670286MB (5468746752 512 byte sectors: 255H 63S/T 340413C)

newfs /dev/da2 works without a problem, while following steps fail:

gbde init /dev/da2
gbde attach da2
newfs /dev/da2.bde 
/dev/da2.bde: 2589368.7MB (5303027136 sectors) block size 16384, fragment size 2048 using 
14091 cylinder groups of 183.77MB, 11761 blks, 23552 inodes.
