If your system goes without software raid, which mean your system access the disk /dev/sda /dev/sdb for scsi, /dev/hda,/dev/hdb for ide.<BR />So you must change this file also.<BR /><BR />I recommend you to make a full backup of your data before you "breake" your system.<BR /><BR />And prepare some rescue CD-ROM<BR />such as <BR /><A href="http://www.lnx-bbc.org/download.html" target="_blank">http://www.lnx-bbc.org/download.html</A><BR /><A href="http://lbt.linuxcare.com/download.epl" target="_blank">http://lbt.linuxcare.com/download.epl</A><BR /><BR />I think this is not "must", but<BR />your current partition ID is "FD" The ext2 fs is "72".<BR />You can change it by fdisk.<BR /><BR />Good luck<BR /> Tue, 01 Oct 2002 03:19:26 GMT I_M 2002-10-01T03:19:26Z https://community.hpe.com/t5/operating-system-linux/break-raid/m-p/2816302#M77594 I have two disk of 9 GB in Linux RAID, I have to break the raid, to use two disk separate.
