Hi:
Excause me, I am not very good at English. We have a luster cluster with IB network .
1. mgs config like below , I think can access with tcp and o2ib
$ more /etc/modprobe.d/lustre.conf
options lnet networks=o2ib0(ib0),tcp0(ib0)
$ tunefs.lustre /dev/mapper/mdt1
checking for existing Lustre data: found CONFIGS/mountdata
Reading CONFIGS/mountdata
Read previous values:
Target: majorbio-MDT0000
Index: 0
Lustre FS: majorbio
Mount type: ldiskfs
Flags: 0x5
(MDT MGS )
Persistent mount opts: user_xattr,errors=remount-ro
Parameters: mdt.identity_upcall=NONE mgsnode=192.168.10.110@o2ib,192.168.10.110@tcp
Permanent disk data:
Target: majorbio-MDT0000
Index: 0
Lustre FS: majorbio
Mount type: ldiskfs
Flags: 0x5
(MDT MGS )
Persistent mount opts: user_xattr,errors=remount-ro
Parameters: mdt.identity_upcall=NONE mgsnode=192.168.10.110@o2ib,192.168.10.110@tcp
exiting before disk write.
when a client with IB network can run the command " mount -t lustre
192.168.10.110@tcp:/majorbio /mnt/lustre " successful .
then, I config the IB network with vmware ESXI as this article
http://www.bussink.ch/?p=1306 ,vmware ESXI can display the IB network as eth
equipment.
On the virtual machine (centos 6.6 ) , I install module lustre, lnet ,
$ lctl ping 192.168.10.110@o2ib
failed to ping 192.168.10.110@o2ib: Input/output error
$ lctl ping 192.168.10.110@tcp
12345-0@lo
192.168.10.110@o2ib
192.168.10.110@tcp
the problem is , when I mount the lustre file system
$ mount.lustre 192.168.10.110@tcp:/majorbio /mnt/lustre/
mount.lustre: mount 192.168.10.110@tcp:/majorbio at /mnt/lustre failed: No such file or
directory
Is the MGS specification correct?
Is the filesystem name correct?
If upgrading, is the copied client log valid? (see upgrade docs)
