I install cpanel on few rh 7.3 box with raid 1 and works fine.
Raid work layer below application so you really sholdn't have any problem with any sofftware if your RAID is setuped well.

Wich raid type you would like to implement ?

Thank you for your reply. Can you please tell me which raid software you used and what precautions should I take before implementing it. I am planning for Disk Mirroring. Since I already have around thousand sites on my server I want to do it with minimum down time. I have never done this before.

Thank you,

we used raid 1 before on a 7.2 or 7.1 server, everynight it would crash to the point, it crashed so much, we had to rebuild the journel....boot partion...etc....Nick was a great help

Later on, we sold the machines, and another company that uses CPanel had told us when cpanel does its nightly check, it also checks out the raid configuration or something like that, and that was likely causing our crashes.

the machines we bought were from some company located there in Fremont, CA

So configuring raid on rehat 7.3 using WHM may even crash the server if something goes wrong. Do we require pysical access to the server while configuring the raid or ssh only is enough.

not likely for every raid system, i honestly cant remember the system we had, if you have access to the machine, go ahead and configure it with raid, you will know pretty much right off the bat if the server suddenly stopps responding say 4am, its likely due to that issue we had...but yah never know


I know they had told me how to disable whatever it was checking for, but at that point, we no longer had the machines, one went to NZ the other to WA i think ;)

Have several boxes running the included software raid on RedHat 7.x with no problems. A power failure caused the drives to get out of sync, but that was easily corrected remotely.

If you have a live box and want to move customers to a raid array, you're in for a bit more work than starting from scratch. I've done it a few different ways, and never really found a method that is more fun than just moving the customers to a different box or adding new mirrored drives and moving the customers to the new disk array.

If your looking for a backup solution, i gave up (due to those raid issues) on raid along time ago

What i do is this for an existing or new system

* create 2 hard drives, both with their own OS's both setup as hda

* once first hard drive has cpanel installed etc...is "live" i edit fstab and bring the 2nd drive as /usr2 .... /var2 ... /home2

then i use rsync and copy over everything related to Cpanel, if you want the script, email me....i run our backups every other night
