[lustre-discuss] mounting failover MGS and MDT

[Cory Spitz]

Ravi,

The section of the Lustre Operations Manual on configuration should be what you need: http://doc.lustre.org/lustre_manual.xhtml#configuringlustre and http://doc.lustre.org/lustre_manual.xhtml#dbdoclet.50438194_88063.  Simply skip the --mdt option when making the MGT like so: mkfs.lustre --fsname=fsname --mgs /dev/block_device.

Please refer to the documentation for more details.

Subject: [lustre-discuss] mounting failover MGS and MDT

Hi

I am trying to configure Lustre 2.8 with two nodes for MGS/MDT with failover.
I have single attached shared storage to MDS servers. My shared storage partitions are

mpathb – 100G fot MGT
mpathc – 800G for MDT

Now what is the command to create MGS and MDS from mkfs.lustre?
Should I create MGS first and later MDS? How do I specify servicenode option?

Any help is highly appreciated.

Regards
