DragonFly 3.6 can't be installed on a 6TB volume
I tried to install DragonFly on a batch of Xeon E5v2 workstations.
These machines have a 6TB mfid0 boot volume (RAID 5 of 4x2TB disks on a LSI 9260-4i adapter).
The installation fails almost immediately and these messages are shown in a dialog box:
fdisk: WARNING line 1: number of cylinders (726552) may be out of range
(must be within 1-1024 for normal BIOS operation, unless the entire disk is dedicated to DragonFly
fdisk: ERROR: could not adjust partition to start on a head boundary and end on a cylinder boundary.
- Category changed from Driver to Kernel
This issue neither specific to the disk size nor to the mfi(4) driver generally.
We have a guy in the IRC channel who runs DragonFly on a large system with (IIRC) 15x3TB with mfi(4):
