sanity test_802 - set mdt quota type failed

Hongchao

Could you please investigate?

Thanks

Comment by Andreas Dilger [ 02/May/18 ]

This failure seems start showing on 2.11.50.51, b3738 on April 9, 2018

It probably makes sense to see which quota-related patches landed just before then.

Comment by James Nunez (Inactive) [ 28/Jul/18 ]

sanity test 802 fails when we run the ‘full’ test group, but passes for all other testing; review-ldiskfs, review-dne, etc. On difference between full and all other testing is, for ‘full’ testing, we enable quotas for all test suites and for all other testing, we don’t enable quotas.

For sanity test 802, we stop all servers and then mount the servers as read only. When we bring up the server, in read only mode, we try and reset quotas in setup_quota() and the following call to conf_param on the mgs fails

2119         do_facet mgs $LCTL conf_param $FSNAME.quota.mdt=$QUOTA_TYPE ||
2120                 error "set mdt quota type failed"
2121         do_facet mgs $LCTL conf_param $FSNAME.quota.ost=$QUOTA_TYPE ||
2122                 error "set ost quota type failed"

One question is, is Lustre behaving properly and not allowing calls to conf_param when a server is read-only or, more specifically, should we be able to set quotas by calling conf_param on a read only server?

Comment by Andreas Dilger [ 28/Jul/18 ]

Since enabling quota requires changes to the filesystem on the targets, it doesn't make sense to enable it on a read-only filesystem.
