Description

sanity-quota test_3 fails with 'write success, but expect EDQUOT', but looking at the client test_log we see

Total allocated inode limit: 0, total allocated block limit: 0
pid 1000 is using default file quota setting
Files for project (1000):
lfs: failed for '/mnt/lustre': Too many levels of symbolic links
 sanity-quota test_3: @@@@@@ FAIL: write success, but expect EDQUOT 
  Trace dump:
  = /usr/lib64/lustre/tests/test-framework.sh:6115:error()
  = /usr/lib64/lustre/tests/sanity-quota.sh:152:quota_error()
  = /usr/lib64/lustre/tests/sanity-quota.sh:771:test_block_soft()
  = /usr/lib64/lustre/tests/sanity-quota.sh:827:test_3()

There is no additional errors or indication of a problem in any of the console logs.

We’ve only seen sanity-quota test 3 fail with this error and with the lfs error:
https://testing.whamcloud.com/test_sets/7a25bb86-d6ed-11e9-a2b6-52540065bddc

We've seen sanity-quota test 3 fail with the same "write success, but expect EDQUOT " error, but the test_log does not have the lfs error. The logs have a different failure:

Total allocated inode limit: 0, total allocated block limit: 0
Some errors happened when getting quota info. Some devices may be not working or deactivated. The data in "[]" is inaccurate.
