This log message is very critical for the quota monitoring feature in RHSC. So, i have marked the bug as a development blocker and also put the severity at High. Quoting from Varun's e-mail on this BZ. ====================================================== In the meantime to not to block the testing and development of the dependency features you can use the below two options of Quota. gluster volume quota <volname> hard-timeout 0 gluster volume quota <volname> soft-timeout 0 gluster volume quota <volname> alert-time 0 <or-a-very-minimal-value-in-the-order-of-seconds> Upon setting these configurations, quota never skips the logging. ====================================================== Do setting these values have any performance impact? Yes, these settings may reduce the performance a bit. But this is the only way to ensure the logging in all the cases. Setting flags required to add BZs to RHS 3.0 Errata The logging is done after the check for the soft limit cross on every write. Without the quota size updation from all the bricks, quota doesn't know whether the soft limit has crossed. This is a problem of trade off between correctness vs performance. As suggested in the comment #3 for the accurate logging one should tune the soft timeout and hard timeout to zero. Hi Varun, Please review the edited doc text for technical accuracy and sign off. based on the steps provided in comment#3 of this BZ, the alert messages are seen even after limit are reached. But there are many alert messages now. Since, this BZ is only about getting alert messages in logs after limit have reached, hence moving to verified.
