Simple. Raid 5 requires three partitions at minimum to work. See http://linuxdocs.org/HOWTOs/Software-RAID-HOWTO-2.html. If you only have two disks, you will want to do raid 1 to achieve redundancy (mirroring). BTW. The common belief about raid is that only user data (/home) should be mirrored. Mirroring other data (/usr, ...) only incurs a performance penalty (only slight for reads, but a lot for writes). Remember that every time you write something to /tmp, it has to be written to disk TWICE! And let's be honest: with software raid, and in the situation below, if one of your disk fails, your system crashes anyway (because of the distributed swap if nothing else). For all filesystems that hold no user data, you can even use raid 0 (striping) for increased performance. And last, I'd be really careful putting /boot on a raid device. It's an invitation for trouble since lilo doesn't know how to handle raid devices, but has to read from them nevertheless.

I'm trying to completely format my two identical 2.2GB SCSI drives, within the kickstart process. I would like to end up with two identically partitioned drives, including having the swap space span both disks. I also require that the highest possible level of duplication is used on all filesystems. Under RH7.0, anaconda spits out this error message, "partition command requires one anonymous argument." What am I doing wrong below to cause this? ========================================================================== zerombr yes clearpart --all part raid.00 --size 32 --ondisk sda part raid.01 --size 32 --ondisk sdb # md0 = /boot part swap --size 400 --ondisk sda part swap --size 400 --ondisk sdb part raid.10 --size 400 --ondisk sda part raid.11 --size 400 --ondisk sdb # md1 = / part raid.20 --size 400 --ondisk sda part raid.21 --size 400 --ondisk sdb # md2 = /usr/local part raid.30 --size 200 --ondisk sda part raid.31 --size 200 --ondisk sdb # md3 = /var part raid.40 --size 200 --ondisk sda part raid.41 --size 200 --ondisk sdb # md4 = /tmp part raid.50 --size 200 --ondisk sda part raid.51 --size 200 --ondisk sdb # md5 = /opt part raid.60 --size 200 --ondisk sda part raid.61 --size 200 --ondisk sdb # md6 = /home raid /boot --level 1 --device md0 raid.00 raid.01 raid / --level 5 --device md1 raid.10 raid.11 raid /usr/local --level 5 --device md2 raid.20 raid.21 raid /var --level 5 --device md3 raid.30 raid.31 raid /tmp --level 5 --device md4 raid.40 raid.41 raid /opt --level 5 --device md5 raid.50 raid.51 raid /home --level 5 --device md6 raid.60 raid.61 __________________________________________________________________ Get your own FREE, personal Netscape Webmail account today at http://webmail.netscape.com/ _______________________________________________ Kickstart-list mailing list Kickstart-list@xxxxxxxxxx https://listman.redhat.com/mailman/listinfo/kickstart-list
