[lustre-discuss] lfs_migrate transfer question

[Jérôme BECOT]

Hello,

As we had a inode usage issue, we did as Andreas advised :

- add a new ost with much more inodes
- disable the first ost
- use lfs_migrate to move files to the new ost

We have about 16M files on this OST (7.5TB). Our OSS are connected via 
10Gbps Ethernet, though the lfs_migrate command has been launched on a 
1Gbps connected client.

It's running for 5 days and is at about 50% now. It's pretty slow.

Since the command has been launched on a client, does the data transit 
through it ? Is there any way to improve performances ? (we will have to 
move data from the 2nd ost back once the first one will get more inodes, 
then reformat it, then rebalance)

Thank you
