Hi there,
I have just started a new position with a company that has a nice 20 node cluster. This cluster is a nice setup, except they have not got any shared storage setup, they did have NFS configured but the read times they were getting for processing data was slowing the cluster down considerably. After looking around I have found lustre and thought I would configure it on a spare node and see what kind of results I can get from it. So I have a system running Redhat Enterprise V 4 and have downloaded the the pre built RPM's from the following area on clusterfs.com http://www.clusterfs.com/downloads/public/Lustre/v1.6/Production/latest/ rhel-2.6-i686/ I've installed the new kernel and modified the grub.conf file so it is being booted up. Also I have installed Kernel-lustre-source Lustre-1.6.3-... Lustre-debuginfo Lustre-ldiskfs Lustre-modules Lustre source Now at the moment I have a second 70Gb sata drive on the system I would like to use as the lustre drive, so following the instructions I have used the following command Mkfs.lustre -mdt -mgs /dev/sdb Which shows up all the right messages and is successful, I then mount the drive Mount -t lustre /dev/sdb /test_share which successfully mounts and I can look at "cat /proc/fs/lustre/devices" and can see all the right information. Now the thing is if I try and write to this filesystem I get an error Not a directory ???? So I'm kinda lost. What am I doing wrong ??????? If I mount the filesystem with a standard command Mount /dev/sdb /test_share I can see the following files and directories listed [EMAIL PROTECTED] /]# ls /test_share CONFIGS last_rcvd lost+found OBJECTS ROOT health_check LOGS lov_objid PENDING Help. _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ SCRI, Invergowrie, Dundee, DD2 5DA.
