Did you install the development tools? Do a "yum groupinstall 'Development Tools'" should solve this

[Amitkumar Ghatwal]

I tried below but it failed to install

[root@pts00433-vm3 lustre-stable]# yum groupinstall 'Development Tools'
Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-manager
Maybe run: yum groups mark install (see man yum)
No packages in any requested group available to install or update

next also tried below
[root@pts00433-vm3 lustre-stable]# yum groups mark install "Development Tools"
Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-manager
Marked install: Development Tools

[root@pts00433-vm3 lustre-stable]# yum groups mark convert "Development Tools"
Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-manager
Converted old style groups to objects.

still the same errors
[root@pts00433-vm3 lustre-stable]# yum groupinstall "Development Tools"
Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-manager
Maybe run: yum groups mark install (see man yum)
No packages in any requested group available to install or update

Any pointers on above , how to get "development tools" installed.?

[Amitkumar Ghatwal]

Hi @James A Simmons ,

Thanks for your suggestion.

Just an update , i changed my machine and i was able to install "development tools" on it and it helped me with building lustre from source. So here i want to just start alustre client on this machine .As i already have MGS/MGT,MDS/MDT running on machine 1 ( centos x86_64 ) , and OSS/OST running on machine 2 ( centos x86_64 ) . In the past i had working 3 note set up wherein lustre client was deployed on centos -x86_64 machine 3 (centos -x86_64 ) .

Now i want to replace lustre client on x86_64 (machine 3 ) by setting up lustre client on ppc64le-rhel7.2 .

1. git clone git://git.hpdd.intel.com/fs/lustre-release.git
2. cd lustre-release/
3. sh ./autogen.sh
4. ./configure --disable-server
5. make
6. make install

To ensure that the lustre version showing up is now

1. ./LUSTRE-VERSION-GEN
   2.8.60
2. whereis lustre
   lustre: /usr/lib/lustre /usr/include/lustre /usr/share/lustre /usr/share/man/man7/lustre.7

So it appears to me lustre is built from source and m on track to start lustre client on this , however i am getting errors when i try to start the lustre client
Next to try to Load the lustre kernel module:

1. modprobe lustre
   modprobe: FATAL: Module lustre not found..

Has anyone faced such issues whilst setting up the lustre client ( am assuming that i have managed to build lustre from source sucessfully ) . Let me know if i am missing any step in configuring this machine to act as lustre client.

Regards,
Amit

Try running "depmod -a" after you install the lustre modules.

[Amitkumar Ghatwal]

Yes , that is what i did yesterday and got it working, but replying it here now
Next below commands was how i managed to install lustre client

1. depmod -a
2. modprobe -v lustre

Installed at power up
[root@pts00433-vm5 ~]# cat /etc/sysconfig/modules/lustre.module
#!/bin/sh

/sbin/lsmod | /bin/grep lustre 1>/dev/null 2>&1
if [ ! $? ] ; then
/sbin/modprobe lustre >/dev/null 2>&1
fi

connect to MGS/OSS

1. mkdir /mnt/first_mount
2. mount -t lustre 10.51.225.95@tcp0:/whatevs /mnt/first_mount

Confirming that the client is configured correctly
#[root@pts00433-vm5 ~]# lfs df -h
UUID bytes Used Available Use% Mounted on
whatevs-MDT0000_UUID 28.4G 58.9M 26.3G 0% /mnt/first_mount[MDT:0]
whatevs-OST0000_UUID 39.5G 57.0M 37.3G 0% /mnt/first_mount[OST:0]

filesystem summary: 39.5G 57.0M 37.3G 0% /mnt/first_mount

1. [root@pts00433-vm5 ~]# df -h
   Filesystem Size Used Avail Use% Mounted on
   /dev/mapper/rhel-root 115G 88G 28G 77% /
   devtmpfs 7.5G 0 7.5G 0% /dev
   tmpfs 7.5G 0 7.5G 0% /dev/shm
   tmpfs 7.5G 137M 7.4G 2% /run
   tmpfs 7.5G 0 7.5G 0% /sys/fs/cgroup
   /dev/vda2 497M 310M 187M 63% /boot

   tmpfs 1.5G 0 1.5G 0% /run/user/0

The above tells me that machine 3 is successfully configured to be working as lustre client . Do let me know of any more check/test which i can perform on the lustre client to conform lustre file system.

[Amitkumar Ghatwal]

Hi James A Simmons,

Are there any test cases which can be run to validate the lustre client configuration/performance when build lustre from source as done above ?
