[lustre-discuss] Using lctl lfsck syntax issues

[Ms. Megan Larko]

Thanks, Andreas.   That worked.

EXAMPLE: on MDS
> lctl lfsck_query -t namespace -M meg1-MDT0000
namespace_mdts_init: 0
namespace_mdts_scanning-phase1: 0
namespace_scaning-phase2: 0
   .
   .
   .
namespace_repaired: 0

Currently the values for me are all zeroes--happy file system.

Cheers,
m
