On 2001-05-07, Bob Greene scribbled: # Well, you wrote the book; I've only read it. Is this a vinum specific # performance penalty? I think the performance penalty affects almost every RAID 5 array, since you have to update the ECC data on all of the remaining drives so that the entire file system is still accessible. If I remember correctly... you can still have all your data as long as no more than one drive were to fail in a single array at any given time. To unmangle that... if you lost one drive already and another one fails... I think your screwed. -- Linh Pham [lplist@closedsrc.org] // 404b - Brain not found To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
