in the archives, i see some discussion of jfs issues at install time for FC2, but none for FC4... i just attempted to install w/jfs on an IBM X330, which failed. i then went through the exact same install using ext3 instead of jfs, and it worked perfectly. the root problem appears to be that the filesystems aren't being formatted/built properly; i see the dialogs showing ext3 partitions being formatted when i do that install, but i don't see dialogs for jfs partitions, it seems to skip that and try and install rpms directly. more details follow the next question... additionally, does anyone have any direct experience with jfs on FC4? comments on stability? i'm not interested in conventional wisdom, but in opinions of those with experience. i know of people running postgresql in production on jfs, with no problems and a nice performance boost, so i'm thinking that conventional wisdom that it's not ready for prime time may be obsolete. now for the details... the setup is a conventional LVM on top of Software RAID, with a small RAID-1 partition for /boot at the start of the two drives, one swap partition on each drive, and a large RAID-1 partition for a logical volume for the usual suspects, er, partitions. when i make these jfs in disk druid, it claims things went fine and then fails to install the very first RPM, with a vague message that amounts to "bad media or hardware problem or maybe something else". this is reliably repeatable. when i went through the same install with Disk Druid, setting file systems to ext3, everything went fine. should i try the "format with Knoppix, then install" trick? thanks, richard -- Richard Welty richard.welty@xxxxxxxxxxxxxxxxx 518-626-3023
