[Lustre-discuss] lustre error about ldlm process

[huangql]

Hi,

Thank you for your advice!
I wonder that the lustre error is a bug for version 1.6.6 or not. We plan to upgrade the server to 1.8.1.1, Does the  bug fix? And I still don't know why so many ldlm processes exsit in server, is it normal? Can someone give me more details about this? Thanks a lot!

Thanks,
Sarea

We experienced the same with 1.8.1 servers and 1.8.0.1 clients.
Two weeks ago we upgraded the servers (2 MDS, 5 OSS) to 1.8.1.1 and
haven't seen this behaviour since.
