Alright, following setup: 2 identical machines (DELL Power Edge T320) with a hardware raid.one machine is running for a while now, one machine hasn't even been set up at allThe running machine has a RAID 0+1. 4 disks (4TB each) in total all togetherThe task:cloning the running machine with everything on there and everything like it is configured on the second machine. They will be used at two different locations but need exactly the same system and data to start from. The state, the running system is in should be used as this desired state and we want to have the complete system on the second machine as well.The idea:checking the raid to be syncronized on machine 1once it's syncronized, exchanging two hard drives (e.g. 1 and 3) with two empty oneswaiting until they are syncronized againexchanging another two harddrives (e.g. 0 and 2) with another two empty oneswaiting until they are syncronized againputting the 4 original harddrives back in machine 1putting the 4 copied (via RAID) harddrives in machine 2 and have a cloned copy of machine 1 on machine 2That would you say to such idea? Thanks!
Clone installed system by using the hardware RAID 0+1 synchronization
raid;raid1;raid0
Start situationA1+A2+A3+A4.after first permutationB1+A2+B3+A4disk A1 and A3 have data at stage 1after second permutationB1+B2+B3+B4disk A2 and A4 have data at stage 2putting together A1+A2+A3+A4 gives data at stage 1 and 2, the only way that those data are sync is to have the OS down and let hardware raid do the sync.This might be a problem if you system is in production.You might want to:shutdown OS #1Pull and replace disque A1 and A3Verify system #1 workon the new system install A1 and A3 (without A2 and A4)run system #2 and add new disk (and let raid do the sync)
