What distro? What > kernel? What disk controller? What disks? Both of my data-points are several years old so most of the details are lost in the fog-of-lost-memories... Both were on desktop class hardware with onboard IDE or SATA. If I remember correctly one was on CentOS(4?) and one was on either an old Ubuntu or a classic debian (atleast we're talking 2.6 kernels). My main point was that, nope, linux-md is not the holy grail either. The only storage products that I've not had fail me tend to be either: 1) Those that are too new (give them time) 2) Those that I havn't tried (in scale) yet (which always gives a strong "the grass is greener on the other side feeling") /Peter > I'm interested in this because I have never seen Linux software MD RAID1 > failures like this, but some people keep telling they happen frequently.. > > I'm just wondering why I'm not seeing these failures, or if I've just > been lucky so far.. > > -- Pasi
