| Doc Text: |
When a block storage domain exceeds a certain number of logical volumes defined in a configuration value, each action that results in the creation of a new logical volume on the domain will add an audit log warning that the number of logical volumes on that domain has exceeded the defined number. The number of logical volumes is defined in the configuration value 'AlertOnNumberOfLVs' and it's default value is 300.

Let's have a warning on creating a snapshot (or doing LSM) after 300 volumes (confuigurable) (In reply to Allon Mureinik from comment #3) > Let's have a warning on creating a snapshot (or doing LSM) after 300 volumes > (confuigurable) Hi LVs are not only snapshots but also templates and disks. in case the limit is 350 than it is for all kinds so warning only about snapshots isn't good enough Am I wrong? anyway it sounds like we should test only the limit - reach the limit to get the warning, doesn't matter how. we can set the limit to 5, create 5 LVs and check we get warning. please approve.

Every volume is an LV - this can be the first volume in a image (i.e., when you create a disk), or any other one (when you create a snapshot). A template itself is not an LV - its disks are. > in case the limit is 350 than it is for all kinds so warning only about > snapshots isn't good enough Yup, see above. > anyway it sounds like we should test only the limit - reach the limit to get > the warning, doesn't matter how. we can set the limit to 5, create 5 LVs and > check we get warning. We should test that every flow that adds an LV has this warning. This RFE is verified on rc1,though the message appears only on engine's log: 2014-08-24 12:15:23,264 WARN [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (ajp--127.0.0.1-8702-7) [79950f3d] Correlation ID: null, Call Stack: null, Custom Event ID: -1, Message: The number of LVs on the domain iscsi exceeded 30, you are approaching the limit where performance may degrade. This warning could be missed quite easily,depending on the traffic of-course. Anyway,my opinion is that UI should prompt a warning message as well. what do you think,Allon? It should appear in the alerts bar. Doesn't it? nop,it doesn't. I have set AlertOnNumberOfLVs=30 I have almost 60 lv's now,the warning appears only on engine.log Tal, can you take a look at this please? I'm moving it back to ON_QA based on Allon's comment #7,please notify me if a warning on engine.log file is satisfying for a verification of this RFE... following comment #7, reopening Ori, I've just checked and the warning does appear in the events tab, not to mention that if you saw that AuditLogDirector line in your log, it means that it persisted an event log. Please check again, make sure you open the events tab to see all late events so a newer event won't mask out the event you are looking for Guys, lets close this. Tal, Ori, please add screenshots of the system [not] showing the desired event - I'm guessing the message appears in place X while Ori was looking at place Y. Created attachment 930822 [details]
