Rebuilding RAID 5 disk array ?
Posted on 2005-04-08
I have a 4 x 200 GB SATA RAID 5 disk array with only 20% used space. Today one disk failed and I took it out.
Is it safe to continue running this disk system with only 3 disks? Is there enough data redundancy to allow for another disk failure? Should I rebuild the 3 disk array now? Obviously, the failed disk will be replaced, but that might take some time.
The array is part of a Red Hat 9 Linux data server.
