[mythtv-users] Logical Volume (LVM) - question

[Ali Asad Lotia]

thats heavily dependent on what kernel you have. i don't know if the
kernel has jfs support by default. perhaps you need to pass it a boot
time argument to enable jfs support. also did you try just fsck on the
volume using the fsck.jfs? perhaps there is some corruption that needs
to be corrected before the fs will mount.
