Hi,
I want to restart all the servers of my Lustre File System. In what order I need to reboot
the machines? The MGS and MDT are using separate disk partitions but reside on the same
machine. I have eight OSSes, each with one OST.
Could you please some suggestions?
Thanks very much.

Hi Yizheng,
I would recommend the inverse of this procedure to poweroff lustre
http://build.whamcloud.com/job/lustre-manual/lastSuccessfulBuild/artifact...
. Then restart it again.
Kind regards

The process I tend to favour, if the MDT and MGT are separate, is:
1. umount clients
2. umount MDT[s]
3. umount OSTs
4. umount MGT
...then reboot world.
