For now, I tend to prefer hard raid disk instead of logical raid disk on PC server. But as you're looking for it there's a mirror option in lvm, so soft raid is not the only solution. lvcreate [--addtag Tag] [--alloc AllocationPolicy] [-A/--autobackup y/n] [-C/--contiguous y/n] [-d/--debug] [-h/-?/--help] [-i/--stripes Stripes [-I/--stripesize StripeSize]] {-l/--extents LogicalExtentsNum? ber[%{VG|PVS|FREE}] | -L/--size LogicalVolumeSize[kKmMgGtT]} [-M/--persistent y/n] [--minor minor] [-m/--mirrors Mirrors [--nosync] [--mirrorlog {disk|log}] [--corelog] But there's still a problem, it needs a third disk for the log or the mirror will be reconstructed at each reboot. |

Hi, Hardware RAID is not applicable in all cases, in mine it is not for what I want to do. I need to mirror 2 FC disks from 2 disk arrays, this is not Hardware RAID possible. cf my blog at http://brehak.blogspot.com/2008/08/lvm2.html for detailed explanation on what I'm trying to do The thing would be to submit RFE's to the LVM2 development team, based on the most popular features, especially taking into account the professional uses of Linux. |
