Please tell more about your hardware and software. 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.
But it does have the advantage of not adding _extra_ things to break. If your CPU/RAM/disk controller fail you are pretty much dead anyway, and with md you can move the disks/array to a new system without having to match the exact controller. With md raid1 you can access any single disk directly if that's all that still works.
The only storage products that I've not had fail me tend to be either:
- Those that are too new (give them time)
- Those that I havn't tried (in scale) yet (which always gives a strong "the
grass is greener on the other side feeling")
Everything breaks eventually (or has fire/flood/earthquake damage). Backups and redundancy are the only solution to that.
