Description

Hi ,

We have lustre 2.0 at our setup with 2 mds servers and 6 oss servers.

Facing an issue where "lfs check servers" output varies from node to node.

Please find below the outputs of two different clients took at the same time.

Request your help in solving this issue.

Also find attached var log messags of the node having this error.

[root <at> cn367 ~]# lfs check servers

scratch-OST0011-osc-ffff810c01a9c000 active.

[root <at> mgmt00 ~]# lfs check servers

error: check 'scratch-OST0011-osc-ffff810c056c4000' Resource temporarily unavailable

Thanks & Regards,
N.Chakravarthy.
