Cool redhat - format and then re-mount 4tb raid 5 part. ?


I have a server with CentOS 4 and a hugh RAID5 partition with an Adapted 2820SA controler. Few days ago the drivers for CentOS 5 have been released and as the server freeze sometimes I would like to try with the CentOS5 (red hat enterprise 5)...

There are 2 partitions ... one for the system and one for the datas. I can erase the system but of course not the datas

My /etc/fstab looks like :

# This file is edited by fstab-sync - see 'man fstab-sync' for details
/dev/VolGroup00/LogVol00 /                       ext3    defaults        1 1
LABEL=/boot             /boot                   ext3    defaults        1 2
none                    /dev/pts                devpts  gid=5,mode=620  0 0
none                    /dev/shm                tmpfs   defaults        0 0
none                    /proc                   proc    defaults        0 0
none                    /sys                    sysfs   defaults        0 0
/dev/VolGroup00/LogVol01 swap                    swap    defaults        0 0
/dev/sdb1  /_array  ext3  suid,dev,exec  0  0
/dev/hda                /media/cdrom            auto    pamconsole,exec,noauto,managed 0 0
/dev/fd0                /media/floppy           auto    pamconsole,exec,noauto,managed 0 0
Could you confirm me that after the CentOS 5 install, I would be able to mount again /dev/sdb1 if I add this line to the configuration's file ???

I think that yes.. but I just want to be sure ))

Thanks you and have a nice day !

just do manual disk partitioning during the installation. Don't touch your /dev/sdb1 partition. You should be fine
