Nathanael hi, Please refer to Aharon suggestion. I don't know if you can extend without going to maintenance, and I don't think that updating the DB directly would be recommended. Regards, Fred ----- Original Message -----

Thank you Fred for your answer, Aharon suggests me : " The flow should be like below -
* Put the relevant domain in maintenance * Extend the lun (from storage side) * Resize the relevant PV (for example - > "pvresize --setphysicalvolumesize 125G > /dev/mapper/3600601601282300056f0075c3f81e311" * Activate the domain
Check the storage domain total size, It should have the new size. "
I have a few question to do it manually:
* Do I have to shutdown or live storage migrate to an other lun all my vms to perform the pv extend on the SPM? I know now it won't update the ovirt db but, is it a risk to do extend this in production? * My next question is : is it possible to fill manually the new lun size in the DB?
All this would prevent me from a heavy maintenance or from a very long migration (4TB) due to maintenance mode.

Hi all,
I've just expanded the lun used as master by the domain storage. fdisk on the SPM is able to see the multipath device with its new size, but engine reports the old size. How to refresh this?
