Re: [Moosefs-users] mfs 1.6.20

[JJ <jj...@ci...>]

What I've also noticed is that the file size is NOT always 0.
It turns to 0 when the "Input/output error" message appears
on my client.

a mount command from my client shows:
mfsmaster:9421 on /mnt/mfs type fuse.mfs 
(rw,relatime,user_id=0,group_id=0,default_permissions,allow_other)

my /etc/fstab entry is:
mfsmount             /mnt/mfs             fuse       defaults 
    0 0

the /etc/mfs/mfsexports.cfg on mfsmaster for my client is
24.101.150.38/32	/ 	rw,alldirs,maproot=0

All other values in same file are commented out or appear default:

# Allow everything but "meta".
*			/	rw,alldirs,maproot=0

# Allow "meta".
*	
...

I'm going to try another popular distro of the Ubu* variety and see what 
happens from there.

Thank you for your time.
