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! ----- Original Message ----- From: "Guy" To: ; Sent: Thursday, July 22, 2004 2:07 PM Subject: RE: Add disks to RAID5 array > 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? > > Guy
