| Post subject: | CF based SBE |
I have been trying to configure a silent frontend for the living room. To keep the noise down I am trying til install to a 2 gig CF card as /dev/hda1. Unfortunately i can't get the auto-install to run properly. It seems like it wants no less that 5 gig as the primary root parttion on the box. I tried just to say yes to partitionning of the CF but in the end it comes out with an error: Mounting of /dev/hda1 Failed. It creates partitions ok and I can create partitions manually and format them. If I try to do a manual install I can't get passed the Partitioning menu. My question is. Is it nessecary to have at least 5 gig disk to install knoppmyth. My Master backend uses only 1.5 gig of disk on the root partition. I have the MBe's /myth partition NFS'ed to the network and my plan was to have the SBE use this volume together with the MBE. If I swap a ordinary 10gig Harddisk in for the CF setup everything installs ok. I shall note that the CF is seen as /dev/hda. The reason I am using SBE instead of Frontend is that the frontend setup can only deliver NSTC output on my PVR350 tv-out. If the living room pc is run as a SBE I ´can get PAL tv-out from the PVR350 My frontend setup is a 1Ghz PIII IBM 6568-m4k with 256 meg ram, onboard sound and ethernet. TV-out is a PVR350. KM is version R5F27 but I have also tried R5D1 and R5F1. the error is the same. /jk |

Never tried it myself, but I have read about it here. |

What I have done along this line is to install to a regular disk, then take the working filesystem and create a cloop image of it to place it upon a 1GB CF. Really it becomes another "remaster" then. |

Late last night i installled R5F27 on a harddisk in the box. I got it to work as a frontend only system with PAL out on my PVR350. A setup that didnt work on R5D1. It uses the MBE through NFS for the /myth dir. It fills 1.8 gigs presently. If I uninstall the backend part and MySQL it fills even less. This evening I will try to copy the partition to a 2 gig Cf card and try that as a disk. I might even try to move /var to the MBE to have the Cf only serve disc reads. I will post my progress. /jk |

Have you thought about netbooting I know of a few people on the board here have had that work successfully. Might be a little less work or maybe not, I haven't tried it personally. |

I tried the netbooting aka the diskless frontend. I could get it to work but again couldn't get it to use the PVR350 in PAL output mode. Everytime I got the fundamentals to work as a frontend only, PVR350 output turned to NTSC. With the netboot setup it was very difficult to edit configurationfiles etc. that's why I thought of a CF based setup to begin with. I have it working now R5F27 with a CF disk, PVR350 outputting PAL to my tv. /myth and /var/log redirected via NFS to the MBE. Great thanks to the team for the R5F27. I am not sure how many packages I can remove to cut down demands for disk size on /. Right now i have removed MySql, Xmltv and Samba. DF -h shows i curently utilize 1,6 gigs of disk space on he 2 gig CF card. I have reserved 100Megs for swap on the CF so I have little space left. I guess the next step would be to convert it into a diskless FE PXE booting of the MBE. /jens |

Realize that linux will constantly write to its root partition -- that kills CF drives in pretty short order as the number of writes is very limited on flash media. I've done this with firewall appliances and the CF media lasts weeks to months. The micro-disk style of CF cards made by Hitachi and Seagate do not have the same write limitations as the flash-based media. |
