  "message": "dm thin: relax hard limit on the maximum size of a metadata device\n\nThe thin metadata format can only make use of a device that is \u003c\u003d\nTHIN_METADATA_MAX_SECTORS (currently 15.9375 GB).  Therefore, there is no\npractical benefit to using a larger device.\n\nHowever, it may be that other factors impose a certain granularity for\nthe space that is allocated to a device (E.g. lvm2 can impose a coarse\ngranularity through the use of large, \u003e\u003d 1 GB, physical extents).\n\nRather than reject a larger metadata device, during thin-pool device\nconstruction, switch to allowing it but issue a warning if a device\nlarger than THIN_METADATA_MAX_SECTORS_WARNING (16 GB) is\nprovided.  Any space over 15.9375 GB will not be used.\n\nSigned-off-by: Mike Snitzer \u003csnitzer@redhat.com\u003e\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\n",
