[Peter Jones]

Hongchao, could you please push a patch to try this out? Thanks!

[Andreas Dilger]

Jian, it is OK to wait_update() in init_facet_vars() for the label to be updated.

[Jian Yu]

Hi Andreas,

In wait_recovery_complete():

                local var_svc=${facet}_svc
                local param="*.${!var_svc}.recovery_status"

And ${facet}_svc was defined in mount_facet():

        label=$(devicelabel ${facet} ${!dev})
        [ -z "$label" ] && echo no label for ${!dev} && exit 1
        eval export ${facet}_svc=${label}
        echo Started ${label}

So, we can not specify the label like $FSNAME.OST0000 directly.

[Andreas Dilger]

What about using $FSNAME.OST0000 ("." instead of "-") for get_param so that it always matches? Or won't it work properly if the MDS isn't fully configured?

[Jian Yu]

onyx-40vm7: error: get_param: */lustre:MDT0000/recovery_status: Found no match

The server target device label was wrong. "lustre:MDT0000" should be "lustre-MDT0000".

In mount_facet() in test-framework.sh, maybe we need wait for the label on device to be changed from "lustre:MDT0000" to "lustre-MDT0000", and then run e2label?

There is a similar way in init_facet_vars() to check whether label contains ffff or not and wait for it becoming initialized.

this should be the same problem as LU-6890, LU-1875, LU-2415
