Hi Ryan.
## Try stopping portmap and xinetd service and then unexporting the export files for that particular IP and then restart your server and then start the service ie portmap and xinetd.Check logs then.
## Please check the following file also /etc/fstab on both server and client.
Best of Luck.

Hi,
I've got a DAS DELL MD1000 with a bunch of SATA drives in RAID 5 configuration
with total space of 5.4TB. This box is attached to a CentOS5 system (kernel
2.6.18-53.1.6.el5).
Any idea how to make this space usable?
Is there a limit how big a partition can be? What is the work around?
Is there a limit how big a file system ca be?
I've tried to partition it but no matter how bug partition I create fdisk
spits out these messages on the console:
---
sdb: very big device. try to use READ CAPACITY(16).
SCSI device sdb: 10248519680 512-byte hdwr sectors (5247242 MB)
sdb: Write Protect is off
---
I decided to not partition the drive and use LVM but the physical volume
stopped at 2TB.
So, right now I can't use LVM because of this 2TB limit and I'm not sure if I
partition the drive how good these partitions are because of the the message
from fdisk.
Any help or idea is highly appreciated.
Thank you
Peter

I have a server (RHEL 5) that makes 2 directories available to a bunch
of clients via NFS. I keep seeing this particular message in the
servers log:
Feb 8 15:02:12 sapphire kernel: portmap: server 192.168.101.164 not
responding, timed out
The machine, 192.168.101.164 is a client machine that isn't even up at
the moment. I remove the entry from /etc/exports for that machine and
re-ran "exportfs -rv". I still see this message.
The server isn't mounting any file system or anything from the client
machine. Why would I see this message on the servers logs?

You could change the sizing of the 5.4TB logical partition into smaller
logical partitions
Of 2TB in size, make each of these a physical volume and add them to a
volume group, then create a logical volume from that volume group.
I don't know if this 2TB limit will affect this procedure though.
