This issue was created by maloo for Andreas Dilger <adilger@whamcloud.com>

This issue relates to the following test suite run: https://testing.whamcloud.com/test_sets/e0c5003a-4327-11ea-bffa-52540065bddc

test_112 failed with the following error in the test logs:

lfs setstripe: setstripe error for '/mnt/lustre/f112.conf-sanity.0': Numerical result out of range
problem creating f112.conf-sanity.0 on OST0000

It appears that the MDT0000-OST0000 connection has not completed in time, so creating the new file on OST0000 immediately after mounting the filesystem can intermittently fail. The MDS0 debug log reports:

and the client debug log:

when in fact MDT0000 doesn't finish connecting to OST0000 and precreating objects until afterward:
