Re: Diskconfig with RAID and LVM
Hi Michael, Thanks very much. I googled and did some reading. They all suggested that hardware RAID5 is a good choice. Generally speaking, I would hope to get both speed and security. However, I would incline to get security over speed. Sincerely, Tuan On 4/15/05, Michael Tautschnig <[EMAIL PROTECTED]> wrote: > > Hi all, > > > > I am a newbie in unix cluster as well as debian.

Re: Diskconfig with RAID and LVM
Hi all, I am a newbie in unix cluster as well as debian. My lab has a cluster. The main server has RAID. There are 8 disks. The control card has a bios. When it boots, I have an option to build a raid array (volume, RAID0 (stripe), RAID5 or RAID10(stripes of mirror)). However, some of these options (RAID5 and RAID10) were not regconized by Debian sarge kernel (I think the kernel version is 2.6.9-k8). I got an image CD build on Feb, 2005 for AMD64. Furthermore, Debian sees it as a single SCSI. If at boot I build more than a single array, Debian would see defferently. Since I am a newbie, I would like to have your opinions. Should I do one of the following and which one is the best option? 1) Install Debian and let Debian kernel control the raid on all 8 disks. 2) At boot, using software make 4 arrays, then install debian and let debian make an raid arrays from 4 scsi "disks" If you have better idea, I would really appreciate your telling me. A concrete example would be great. Cheers, Tuan

Diskconfig with RAID and LVM
hi everybody, I want to use FAI to install some servers. So it would be great to use Software RAID mirroring and dynamic LVM partitions instead of static patitions. Can anybody tell me how to do it, or point me to some HOWTO documents? -- Cheers, Andreas Bock
