[LU-2992] conf-sanity 58: `/mnt/mds/OBJECTS': No such file or directory

• Type: Bug

• Priority: Minor
• Affects Version/s: Lustre 2.4.0
• Severity: 3
• Assignee: WC Triage

Description

conf-sanity 58 is not working at all, in the sense that it can't find or destroy the OSP logs:

CMD: client-26vm7 find /mnt/mds/OBJECTS -type f -delete
client-26vm7: find: `/mnt/mds/OBJECTS': No such file or directory

Fixed via patch http://review.whamcloud.com/9675 "LU-2524 tests: enable conf-sanity/58 on ZFS"

Normally, tests use "/mnt/mds1" as the mount point and feed "mds1" to facet_mntpt(); it is not impossible that "/mnt/mds" does not exist.

Anyway, the test output I posted is a bad example. What I wanted to point out is actually "OBJECTS" no longer exists, even if the test can mount the device successfully.

[Andreas Dilger]

The mountpoint should be the same one that the MDS is originally mounted on:

        local MNTDIR=$(facet_mntpt mds)
        # remove all files from the OBJECTS dir
        do_facet mds "mount -t ldiskfs $MDSDEV $MNTDIR"

I'm not sure how that could be missing. However, in 2.x there are no logs under OBJECTS. It makes more sense to change the test to create the mountpoint, and also delete logs under O/1/d*:

        local MNTDIR=$(facet_mntpt mds)
        # remove all files from the OBJECTS dir
        do_facet mds "mkdir -p $MNTDIR; mount -t ldiskfs $MDSDEV $MNTDIR"
        do_facet mds "find $MNTDIR/OBJECTS $MNTDIR/O/1/d* -type f -delete"

kind of strange that MNTDIR does not exist, I guess we can try to create it before first access?
this is even before knowing if we should fixthe rest of this test or not

It didn't mount the device. It does not matter what file you are looking for it won't be there.

CMD: client-26vm7 mount -t ldiskfs /dev/lvm-MDS/P1 /mnt/mds
client-26vm7: mount: mount point /mnt/mds does not exist
CMD: client-26vm7 find /mnt/mds/OBJECTS -type f -delete
client-26vm7: find: `/mnt/mds/OBJECTS': No such file or directory
CMD: client-26vm7 umount /mnt/mds
client-26vm7: umount: /mnt/mds: not found

Are you sure you configuration / setup is correct?

The logs no longer exist in "OBJECTS". They should be found under "O/1/d[0-9]+". There is no guarantee that all logs there are OSP logs, however. Hence, the test might need to read and parse "CATALOGS".
