Hi,
I had tried to compile the kernel with # ./configure --with-kpvfsd. and
Nothing went wrong till 4.4 Installing and configuring clients, I entered #
mknod /dev/pvfsd c 60 0, it return:
mknod: 'dev/pvfsd': File exists
so I continued entered # ls -l /dev/pvfsd, it return
crw--------------- 1 root root 253, 0 Oct 28 1:49 /dev/pvfsd
# chmod 644 /etc/pvfstab
# ls -al /etc/pvfstab
--rw-r--r-- 1 root root 57 Oct 28 10:47 /etc/pvfstab
# cat /etc/pvfstab
frontend-0.local:/pvfs-meta /mnt/pvfs pvfs port=3000 0 0
and i skip the rest and continue to step 5.1(Starting PVFS servers)
i had enter # usr/local/sbin/mgr, # ls -l /tmp, return:
total 60
-rwxr -xr-x 1 root root 0 Oct 28 12:07 mgrlog.jgRInW, mgrlog.SSYgGQ, mgrlod.

...
..
...
# usr/local/sbin/iod, #ls -l /tmp, return <==== at frontend and compute node
total 64
-rwxr-xr-r 1 root root 335 Oct 28 13:29 iolog.KnuVtv
..
...
.
# insmod pvfs.o
insmod: pvfs.o: no such file or directory
# lsmod, return a lot of things but no pvfs can be found within them.
# /usr/local/sbin/pvfsd
bash: /usr/local/sbin/pvfsd: no such file or directory
# ls -l /tmp, i can see pvfsdlog.3WHYFP, pvfsdlog.D0twHS, pvfsdlog.XNtfHS
Then i try to mount the pvfs, but cannot be done.
Thanks for the reply.
