• Reporter: Andreas Dilger

Description

It would be useful to improve the {{/proc/fs/lustre/

{osc,mdc}

/*/import}} file to also print the struct obd_connect_data data fields (as connect_data:) in addition to the connect_flags: field. Something like:

    connect_data:
       flags: 0x12349501
       target_version: 2.4.0
       initial_grant: 2097152
       target_index: 3
       max_brw_size: 4194304
       ibits_known: 0xf
       grant_block_size: 4096
       grant_inode_size: 0
       grant_extent_overhead: 1
       first_transno: 0x5500001234
       cksum_types: 0x3
       max_easize: 4096
       max_object_bytes: 17592186044415
