Will the new sda1 partition be large enough, or is 60GB too big?<br>

<div>What's it for? The OS/DB? If so, drop it and put the OS/DB on a
different drive. An old IDE drive will work fine, SSD if you really
want performance. I used an old 40GB IDE drive from an old TiVo, it
worked great. With 12 tuners you might want something a little more
speedy for the DB though. </div>

<div>Sharing the OS and DB with the recordings is a recipe for lots
of seeks, hosing your I/O speed. Put your swap on the OS drive as well.
For the size of the system you're talking about, the disks holding
recordings should hold ONLY recordings. I'd partition them into a
single partition with XFS. Don't share spindles, it's not worth it. Why
the live TV partition? Just let Myth balance the I/O by putting the
whole-drives in the same storage group. If you find your I/O system
can't keep up, add more disks to the storage group. For this reason,
unless you need huge space, I'd buy 500G or smaller drives and just use
more of them. If you can't fit more disks in there, time to set up a
dedicated backend box. </div>

<div>EXT4 does pretty well with large files, but I still like XFS for
recordings. Set the pre-allocation size up around 500M and you will
keep fragmentation low. Again, keeps seeking down. </div>

<div>It will work, but be more fragile. Back up the data somewhere

<div>My backend has 2GB and rarely uses any swap. It's also running
other processes. So you might be able to get away without swap, I
generally put it in anyway though. If a process needs to use it, it
generally doesn't just it long. </div>

Travis,<br>
<br>
Great points! This is exactly the kind of advice I was seeking... <br>
<br>
The answer to the question of why I have a LiveTV partion is, 'I don't
know, It seemed like a good idea at the time'... IIRC, I think I was
trying to grasp the 'storage groups' concept at the time-
<a class="moz-txt-link-freetext" href="http://www.mythtv.org/wiki/MythVideo_.22_Transition_Guide">http://www.mythtv.org/wiki/MythVideo_.22_Transition_Guide</a><br>

I do have
a 320GB IDE drive in a computer in storage that I can use for the OS,
DB, SWAP, and Multimedia, that is on the USB disk now. I don't know why
this didn't occur to me before... (I seem to be racking up the "DUH"
moments lately...)<br>
<br>
Using this drive would allow me to use both of the SATA drives
for recordings only, and provides enough extra space that I could use
my USB drive as a portable again, which eliminates my need for shared
data directory.<br>
<br>
Doing it this way, my new configuration would look like this:<br>
<br>
/dev/hda (IDE internal disk) - 320GB IDE (298GB formatted)<br>
<br>
hda1, 96GB, mount point /, Ext3<br>
hda2, 200GB, mount point /multimedia, XFS (for videos, music, and
pictures)<br>
hda4, 2GB, SWAP<br>
<br>
/dev/sda (first SATA internal disk) - 500.1GB SATA (460GB formatted)<br>
<br>
sda1, 460GB, mount point /recordings1, XFS
<br>
<br>
/dev/sdb (second internal disk) - 500.1GB SATA (460GB formatted)<br>
<br>
sdb1, 400GB, mount point /recordings2, XFS
<br>
<br>
<br>
Which strikes me as a very simple way to get the most out of my
existing drives...<br>
<br>
So, this is the route I think I want to take, unless there is a
compelling reason not to do it this way.<br>
<br>
Thank you!<br>
