>Number: 1024 >Category: misc >Synopsis: installation may delete partitions on existing boot disk >Confidential: no >Severity: serious >Priority: medium >Responsible: freebsd-bugs >State: open >Class: sw-bug >Submitter-Id: current-users >Arrival-Date: Tue Feb 13 09:20:01 PST 1996 >Last-Modified: >Originator: Paul G. Fox >Organization: American Internet Corporation >Release: FreeBSD 2.1-STABLE i386 >Environment: the machine is a generic DX/66, 2 old MFM hard drives on an AT-style controller, 2 SCSI disks on an adaptec 1542. the system currently runs linux. the boot disk is a 150meg maxtor (i think) with 1224 cylinders. the linux root partition is the last partition on this disk, and spans the 1024'th cylinder. the freebsd install was directed at the second SCSI disk. >Description: i was attempting to do a network install of freebsd to the second SCSI drive. i did this twice: - when asked if i wanted to install booteasy, i said yes and - when asked if i wanted to install booteasy, i said no in both cases, when i attempted to reboot the system when the install was complete, the linux root filesystem could not be found. booting from floppy and running linux fdisk showed that the last partition on the boot drive was missing. re-entering that partition data (from paper hardcopy) made everything okay again -- i.e. there was no loss of data, just the partition table was truncated. i understand that freebsd may not be able to deal with disks with more than 1024 cylinders. but it should not change partitions on such disks, especially if its not installing to them. >How-To-Repeat: >Fix: unknown >Audit-Trail: >Unformatted:
