After some great help in another thread, I've decided to give CentOS 5.3 +<br>
JFS a try for my new system which is my main server and of course,<br>
mythbackend. My question is how would you guys recommend setting up the<br>
RAIDs? I have 4 SATA 500GB, 1 PATA 500GB, and 4 SATA 1.5TB drives. I'm<br>
debating the following options, with the requirements of:</blockquote><div><snip> <br></div></div><br>Ben, <br><br> I used to run a 6-disk software Raid5 for my video partition, but after having a dual-drive failure (yeah a freak thing), I switched to individual disks with storage groups. <br>
<br> I run a Raid-1 for my OS & Database (Mirrored 200GB Sata-II Disks) and 6x500GB Sata-II drives as individual disks. That way if I lose any drives, yeah, I lose some of my programming, but if by chance I lose more than one drive, I don't lose the whole thing (which is what happened to me last time. - 2.4TB of recordings went bye-bye...) <br>
<br> I've also found that the software raid5 was noticably slower on my setup (even with an Athlon 64 X2 4800+ and 2GB DDR2 800 DC ram) - perhaps that's because I have 5 tuners and have very little 'idle' time -- sometimes even all 5 tuners recording at once. (and probably contributing to the dual hardware failures due to high write utilization) -- For example, since I re-built my system 8 months ago - the MythWeb "Recording Statistics" page shows a "Percent of time spent recording" of 93% !!<br>
<br> Even the remote frontends seem much more responsive since I switched to storage groups. <br><br> Anyways, that's just my 2 cents... It's only TV after all!!! ;-) <br><br> J-e-f-f-A<br>
