Hi , seems like we are doing almost the same as you do. Did you setup a propper /etc/raidtab? If you have an old RAID-0 Array try starting it with raid0run. This worked with our system. We moved all the stuff away an generated a new Array. Raid 1 and 5 can be converted by using mkraid --upgrade,

Translucent mode, LVM?

1999-07-28 Thread Egon Eckert
Just curious: 1. What's the Translucent mode? The ability to do linear over RAID-5 etc.? 2. How about LVM (in alpha RAID patches)? Is it the same / incompatible / competition with LVM on http://linux.msede.com/lvm/? Thanks, Egon Eckert
