Oscar,
thanks. since I've started this thread, I actually now installed RH8 in place of RH7.3 .... (hoping to gain jfs that way...)
but, it didn't help much:
during RH8 install process, it *does* recognize the /dev/sdb as 'jfs', BUT, after RH8 completes install, again, no jfs support loaded.
I guess this means that jfs support is loaded during install ?
Yes, it does.
so, I'll re-do the queries below with the current RH8:
# pwd /lib/modules # find . -print | grep jfs ./2.4.18-14/kernel/fs/jfs ./2.4.18-14/kernel/fs/jfs/jfs.o
# modinfo jfs filename: /lib/modules/2.4.18-14/kernel/fs/jfs/jfs.o description: "The Journaled Filesystem (JFS)" author: "Steve Best/Dave Kleikamp/Barry Arndt, IBM" license: "GPL" parm: jfsloglevel int, description "Specify JFS loglevel (0, 1 or 2)"
# pwd /lib/modules/2.4.18-14/kernel/fs/jfs # ls -l total 208 -rw-r--r-- 1 root root 208505 Sep 5 2002 jfs.o
# grep CONFIG_JFS /boot/config* CONFIG_JFS_FS=m CONFIG_JFS_DEBUG=y # CONFIG_JFS_STATISTICS is not set
All these indicate that JFS is definitely supported. For you to mount your JFS formatted partition, 'jfs.o' must be loaded in the running kernel.
As root try this, to load 'jfs.o'
# modprobe jfs (or # insmod /lib/modules/2.4.18-14/kernel/fs/jfs/jfs.o}
# lsmod | grep jfs (this is to see that jfs was loaded)
# dmesg | more (this is another way to see that jfs was loaded)
# cat /proc/filesystems (this is another way to see that jfs was loaded)
If all these indicate JFS is loaded, then proceed and mount your JFS partition.
