oh. sorry. it was mistyping. i have done so. mkfs.ext3 -j /dev/sda1 mkfs.ext3 -j /dev/sdb1 mdadm -Cv /dev/md0 --level=1 --raid-devices=2 /dev/sda1 /dev/sdb1 mount /dev/md0 /data/disk1 scp ... [snip]
Should I do format after make RAID-1(/dev/md0) device? After I format disks(/dev/sda1, /dev/sdb1), do not you compose to RAID-1? Can it make a problem? > You should: > mdadm -Cv /dev/md0 --level=1 --raid-devices=2 /dev/sda1 /dev/sdb1 > mkfs.ext3 -j /dev/md0 > mount /dev/md0 /data/disk1 mkfs.ext3 -j /dev/md0 mount /dev/md0 /data/disk1 2005/12/10, Neil Brown <[EMAIL PROTECTED]>: > On Saturday December 10, [EMAIL PROTECTED] wrote: > > I am sorry because there is no information very. > > > > I currently ext3 file system. > > > > I composed RAID-1(/dev/md0) disk array by order such as lower part. > > > > mkfs.ext3 -j /dev/sda1 > > mkfs.ext3 -j /dev/sda1 > > mdadm -Cv /dev/md0 --level=1 --raid-devices=2 /dev/sda1 /dev/sdb1 > > This is not the way raid1 works. > The raid1 array /dev/md0 will be slightly smaller than either sda1 or > sdb1.
