Adding disks to RH9 Raid 0 ?
A while back, I created a raid0 array when I installed RH9. I am needing to add to this array, and I cannot for the life of me find out how to do such. I did this during the install, and never messed with it again. Now the time has come to make it grow a little bit.
I am running RH9 (shrike) and the array is showing up as /dev/md0. any help would be great! Thanks |
Do you have the setup with only two disks or more? You should be able to hot add it I think by using mdadm.
Something like this might work but read the man pages or howtos for mdadm: mdadm /dev/md0 -a /dev/[new-drive] But in my opinion and your data is worthy to you, drop RAID 0, rebuild it as RAID 1 or something else if you have more than two disks so it's striped with parity. If a drive fails in RAID 0, you pretty much lost most of your data. The only thing RAID 0 does for you is performance but it's sort of like just running with one hard drive without backups, unless you back the data up which I would encourage anyone to do because RAID is not intended as a backup. ;) If you insist on using RAID 0, at least get yourself 4 disks and setup RAID10, or RAID1+0, however you want to call it. |
Just FYI, RH9 is very old and hasn't been supported/had updates for years.
If at all possible, replace with a modern distro eg Fedora/RHEL/Centos. |
