[Users] iscsi discovery issue
by Alex Leonhardt 25 Feb '13

25 Feb '13

Hi All, I've successfully discovered a ISCSI target, however, when I tried to add it as storage to the engine, it complained of being too small, so I resized the file and restarted tgtd on the server. The problem is that the engine doesnt seem to bother re-discoverying the target ? How can I remove its cache / current entries ? It never added it as a storage domain, so it is safe to remove that entry I suppose ? Why would the engine not try to re-read the device stats when "adding a storage domain" ? Thanks Alex -- | RHCE | Senior Systems Engineer | www.vcore.co | www.vsearchcloud.com |

Hello, I'm available to translate the portals in Italian if it is only a matter of documentation writing and no programming involved... Let me know if it can be of any help for others. No problem if the effort merges in RHEVM portals too.. Gianluca

[Users] USB Filter editor
by René Koch 24 Feb '13

24 Feb '13

Hi, RHEV provides a tool called USB Filter editor, which is a windows utility for creating an USB pass trough policy. I haven't seen this tool available with the oVirt project. Are there any plans to release this tool with oVirt, too? As there are many guys from Red Hat on this list - can you give me some information about the use of the SQlite database used by the USB filter editor (license)? Can I create an UI plugin to have the USB filter editor available in oVirt admin portal and use the SQlite database of the Red Hat tool as a data source for the USB devices and manufacturers or is this (for historical reasons) under some proprietary license? Thanks a lot for your answers, René

[Users] Ovirt & iSCSI

Hi All, I was wondering if there is a document that describes in detail how ovirt is working with iscsi and how it creates the disks, etc. etc. on the SAN / iSCSI storage ? I checked the online documentation however cant see it going into much detail. I'd also be prepared to write something up for the documenation section, but I need to get it to work and understand first ;) FWIW, this is a part 2 of a project I'm working on, now moving away from NFS and onto iSCSI (a cheap san solution). Your help would be greatly appreciated. Thanks! Alex -- | RHCE | Senior Systems Engineer | www.vcore.co | www.vsearchcloud.com |
