Re: [Moosefs-users] mfs 1.6.20

Travis and Company:

Ås I have said "It all appears good"
Everything as far as I can tell is a green-light.

/etc/hosts contents all ping with expected responses.
Telnet to the (3 mfs*) hosts:9420 all work via named host or
VIP:9420 as expected.

I unREMarked BIND_HOST = * in mfschunkserver.cfg on mfsmaster and 
bounced the service.

My only issue now still seems to be the inability to store any files 
there from my client reliably.

time dd if=/dev/zero of=/mnt/mfs/100Meg bs=1024 count=102400
dd: writing `/mnt/mfs/100Meg': Input/output error
dd: closing output file `/mnt/mfs/100Meg': Input/output error

I thought CentOS by default used all available IPs when binding.
but it couldn't hurt to be specific. :)

I am now re-reading both
http://www.moosefs.org/moosefs-faq.html and
http://www.moosefs.org/reference-guide.html#using-moosefs

but I could still use a hand getting some non-zero byte file writes going.
