Re: Are there rescue disks that recognise LVM2 and RAID
thank you. to summarize, from the point of view of security (i mean security
to save the os, not the data, which can be easily saved elsewhewere) is that
better to make raid1 (amd64 dual) through linux-debian software or to make
hardware raid1 ? (as far as i understand even hardware raid1 involves some
software and if hardware fails to boot, how to boot?).
notice that for budgetary reasons i am setting up raid1 with a couple of
low-cost 300GB SATA hds. i had preferred expensive SATA, just to have the
scsi-type mechanics, or i had preferred totaly scsi but for the hd size i
need for the computations the budget and the complexity of higher raid
prevented me to go on with scsi.
