| Post subject: | Question about storage groups and mixed SATA PATA setup |
Hi, I'm wanting to add a another drive to my setup with the new release. Current setup is SATA 250gb for the system and videos and SATA 320gb for recordings. I have a 250gb PATA lying around that I'd like to add for more recording space. I'd like to only keep transcoded recordings on the PATA disk. For some reason full bitrate recordings on a PATA disk do not play back smoothly on my system. Does myth w/ storage groups allow you to specify where to keep a recording up so I can keep only transcoded recordings (or at least recordings that will be transcoded) on the PATA drive? Thanks! |

Thanks! The short answer is no. You can specify to record shows to spacific storage group, but it won't store full recordings on one and save the transcoded recording to another. At least not that I know of. The good news is that if you manually move the transcoded recordings from one storage group to another, you don't need to modify the DB. Myth will find it automatically.

Your PATA drive should really be able to handle the higher data rate of less compressed video. The rest of this assumes you are logged in as root and the hard drive in question is /dev/hda. Make sure your dma and read ahead is turned on with something like: Code: hdparm -A 1 -a 256 -d 1 /dev/hda You might add the options "-k 1 -K 1" to make it a little morepermanent. Make sure that you have an 80 connector cable connected to that hard drive, not a 40 pin cable. If it is connected to the same cable as your CD/DVD, try the other one. Make sure your BIOS doesn't have a setting that is forcing it to run in a slow mode. Finally, that hard drive may be on it's last legs. You might run smartctl on it when you have an hour to spare. The following commands will tell you all about the drive, including how long the "long" test will take to run: Code: apt-get install smartmontools smartctl -a /dev/hda | less This will actually test the drive: Code: smartctl -t long /dev/hda Wait how ever long smartctl -t said to, then: Code: smartctl -a /dev/hda | less again and look for anything bad sounding.
