I was expecting a lot from this book. My disappointment is total.

I jumped into it going to the section on RAID disks. There I found countless errors, some excusable typos, but other blatant nonsense or contradictions. For ex., author writes that a RAID-5 requires at least 3 partitions (rightly so), but gives mdadm command line examples (see p.348, 349, 350) where a RAID-5 level is defined using just two (nonsense). For monitoring a RAID array, the author refers on p. 352 to the mdmonitor service, and illustrates how to start this service with command "service mdadm start" (nonsense again).

Icing on the cake comes on page 353 with a section titled "Configuring Bootable RAID". Following paragraphs have nothing to do with how to configure a bootable RAID device. In fact, what follows is a word for word repeat of previous contents on pages 349-350. Last sentence reads : "To more efficiently use space you could use corresponding hard disk partitions as described in the next section". To the reader dismay, the chapter ends right there, without the promised section. I had more than enough, and closed the book, outraged.

This book is, well, a total disgrace. I would politely ask Amazon to withdraw it from its offerings.

This book has more typographical and grammar errors than should be allowed. There are redundant statements. There are errors in some information. This book definitely missed its mark. Don't waste your money. Get a Redhat Enterprise book from a more reputable source/author.
