You need both disks BIOS addressable (preferably hda and hdb or sda and sdb). You also need a LILO that speaks Raid0. I think RH6.2 comes with one. > A big partition (100Gb) which lokks like: > - Raid5 (linux md) > - LVM > - filesystem > > It's a classic schema, but my question is: > Does anyone already tried it? /dev/md0 is a raid5 of /dev/hdb, /dev/hde, /dev/hdg, and /dev/hdl. /dev/md0 is a PV for a VG that has 7 LVs in it. I even have root in LVM. (this requires MD autodetect and an initrd for LVM) > Any success? failure? Drawback? > Does XFS + LVM or JFS + LVM or ReiserFS + LVM be stable enough for > production? Currently you cannot put journaled filesystems on a software raid I believe, because they use the buffer cache in incompatible ways. If I am wrong, someone correct me. Ext2 (what I use) works fine. Raid 0.90 and LVM are both quite stable for production use. > Do they all have resize tools? Ext2 has one I think. I don't generally resize LVs. If you'd like any help setting this up, let me know.
