Yeechang and everyone else who has been so helpful,
I must admit I am quite fascinated by the Raid and NAS discussions, but given that I ran into the same problem of being unable to record two programs at once on my software RAID, I am grateful for Yeechang to try and help steer things back towards my original question. Quick summary: When on a software RAID two programs cannot be recorded when they start at the same time. The second program (always starting 0.3 seconds after the first) does not record and ends up as a 0 byte file. This only happens when the video/recordings is on my software raid. (this is key. i can switch over to another non raided hard drive and have no problems doing the exact same thing!) I an running linux kernel 2.6, 512mb, celeron (fairly fast but a celeron nonetheless). I am using 2 drives in Raid 1 (had same trouble with Raid 5 though) and am using a Sata IDE extender to add sata ports (but this is probably irrelevant as I had the problem before I installed this.) Some people have suggested that the celeron might be the problem, but is this possible? No errors on dmesg, and no errors on mythbackend.log until I try and see the recorded programs on mythweb. Memory is full (as always... is this normal?) but the Swap is empty (only 1%). Top doesnt show Mythbackend anywhere near the top. Here is what my log shows: 2006-01-12 20:59:02.889 Started recording "けものみち" on channel: 4 on cardid: 1, sourceid 1 2006-01-12 20:59:03.029 New DB connection, total: 4 2006-01-12 20:59:03.033 New DB connection, total: 5 2006-01-12 20:59:03.043 scheduler: Last message repeated 7 times 2006-01-12 20:59:03.060 scheduler: Schedule Change 2006-01-12 20:59:03.078 Started recording "白夜行" on channel: 6 on cardid: 2, s ourceid 1 QMetaObjectCleanUp::setMetaObject: Double use of QMetaObjectCleanUp! 2006-01-12 20:59:03.875 Changing from None to RecordingOnly 2006-01-12 20:59:03.877 Changing from None to RecordingOnly 2006-01-12 22:09:00.037 Finished recording けものみち on channel: 4 the 2nd program's video file is 0 byte file size. (and the 2nd program always does not seem to work.) Suggestions so far: celeron cant handle it (cache issues) --- a possibility? memory -- not sure myself drive spinning - maybe the drives are spinning down. this is also possible but as they are sata i cant seem to change them with hdparm. So much frustration!! arg,.... any ideas? raid caching or the likes? (<-- i made that up!) thank you kindly david ps. yeechan -> i am quite excited to hear how your ReadyNAS handles!
