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.

I stopped suggesting and doing such things with members most of the time, especially in Server and Enterprise forums. Most of the users are usually in a corporate type environment and most of the time if they're using an older distro, it probably means they're supporting some legacy product or application. I'm probably sure he's aware that it's old.
