[Lustre-discuss] Experienced New User needing help

[Iain Grant]

Sorry please Ignore me, I have now done a 

 

mount -t lustre 143.234.96.46 at tcp0:/testfs /mnt/test

 

and can write to the /mnt/test area.

I thought I would be able to write to the OST area, apologies

 

Iain

Sorry folks I'm still not getting any life from this. 

I've followed the manual and the following steps 

 

Module options for networking should first be set up in
/etc/modprobe.conf, e.g. 

  # Networking options, see /sys/module/lnet/parameters
  options lnet networks=tcp
  # end Lustre modules

Making and starting a filesystem 


combo MDT/MGS on my single node' 

mkfs.lustre --fsname=testfs --mdt --mgs /dev/sda1
mkdir -p /mnt/test/mdt
mount -t lustre /dev/sda1 /mnt/test/mdt
cat /proc/fs/lustre/devices
   0 UP mgs MGS MGS 5
  1 UP mgc MGC143.234.96.46 at tcp 303242f4-5aa3-5377-4895-90a397d56153 5
  2 UP mdt MDS MDS_uuid 3
  3 UP lov testfs-mdtlov testfs-mdtlov_UUID 4
  4 UP mds testfs-MDT0000 testfs-MDT0000_UUID 3

Then I configured OST on the same node 

mkfs.lustre --fsname=testfs --ost --mgsnode=143.234.96.46 at tcp0 /dev/sda2
mkdir -p /mnt/test/ost0
mount -t lustre /dev/sda2 /mnt/test/ost0

 

when I cd to /mnt/test/ost0 I get

 

Not a directory messages ???

 

If  I do a df I can see the filesystems mounted.

 

When I look at /var/log/messages I can see
