OK, here we go. I am setting up a new data server here at work with bad =
butt SCSI 160 10, 000 RPM drives and I plan on using linux as the OS. =
However, my boss indicated that he wanted a second drive inside to =
mirror the SCSI data disk like NT mirroring. This, of course, is =
because I was not authorized to purchase RAID which is what we need. =
Anyway, how would I accomplish "NT like" disk mirroring in linux. I =
have a few ideas on the matter but I hope some of you have experience =
with this. Should I just setup software raid? Thanks. I will carry =
this question to the meeting tonight so look for a big tall goon in a =
blue shirt and white shorts if you have comments on this.
