Re: Add disks to RAID5 array

I've used raidreconf to convert from RAID 1 to RAID 5 and to grow RAID 5
arrays. I would recommend a UPS. If the power blips, the array will be lost.
Other then that, I've never had any trouble whatsoever with it. IMO,
resize2fs is more dangerous than using raidreconf. I have had resize2fs
corrupt file systems badly before. It's important to run fsck -f both before
and after resize2fs. It catches a lot of minor, fixable problems after the
resize2fs is run. Doing this, I have successfully grown RAID 5 arrays many
times without any trouble.

In any case, backing up is highly recommended if you value the data!

A tool called Raidreconf can do what you want.
I have never used it.
I don't know how much risk there is in data loss.
I would backup my data first!

Find it, read about it, and understand it.

Maybe someone else can comment on the risks?
