After installing RedHat6.1 on /dev/hda I added 2nd hard disk, /dev/hdc, which has same capacity as /dev/hda. Then a RAID1 device, /dev/md0, was created with /dev/hda2 and /dev/hdc2 as the constituent partitions. (/dev/hda2 contains data for /home) After issuing "mkraid /dev/md0" somehow /dev/hda2 was syn'ed to /dev/hdc2, which is blank; thus I lost the data of /home. Is there a way to control which disk is syn'ed to which? Thanks. Jason __________________________________________________ Do You Yahoo!? Send online invitations with Yahoo!
