Comments

[John Hammond]

Probably so. But could you be more specific about where?

[Alexey Lyashkov]

John,

that is just run from lustre checkout directory where developing new patch for LU-3276.
sources ~two days ago.
patch don't touch something in tests.

[John Hammond]

Yes but the test passed and to me the output looks correct for a pass. Do you suspect issues because of the error messages or because of some other aspect?

Note that many of the operations performed above are not intended to succeed but are performed just to torture the special case code backing .lustre/fid. Several of them caused LBUGs or oopses in the past. It it distracting to have the errors printed. Probably we should redirect stderr to /dev/null for the operations we expect to fail.

[Alexey Lyashkov]

I worry about "touch /mnt/lustre/.lustre/fid/f.sanity.154a"
that looks like to typo with accessing to wrong patch.

[John Hammond]

No, that's intentional. From the test:

    echo "touch $MOUNT/.lustre/fid/$tfile"
    touch $MOUNT/.lustre/fid/$tfile && \
        error "touch $MOUNT/.lustre/fid/$tfile should fail."

[John Hammond]

Alexey, based on the discussion I'm closing this as not a bug, please reopen or comment here if you disagree.
