Re: [Users] SAN storage expansion
Hi,
LUNs size are being updated using the multipath mechanism. In order to update storage
domain size, you'll need to update the physical volume size using LVM on you
hypervisors.
Please do the following:
1) Put the storage domain to maintenance
2) Execute on your hosts:
'pvresize --setphysicalvolumesize' with the new physical volume size (150G)
3) Activate the storage domain

Subject: [Users] SAN storage expansion
Hi all,
I'm happily continuing my experiments with oVirt and I need a
suggestion regarding storage management.
I'm using an iSCSI based Storage Domain and I'm trying to understand
which is the correct way to extend it's size some time after it's
creation.
Please consider the following steps:
1) Using storage specific tools create a new volume on iSCSI storage
(e.g. 130.0 GiB)
2) in oVirt webadmin: Storage -> New Domain , select the previously
created storage (130 GB), OK, after some time it's online:
Size: 129 GB ; Available: 125 GB ; Used: 4 GB
3) Use according to your needs (even noop is OK)
4) Using storage specific tools expand the new volume (e.g. 20.0 GiB
more, now it says 150.0GiB)
5) in webadmin: Storage, click on the domain, Edit. Looking at
Luns>Targets , now it correctly sees 150GB
BUT
on the Storage tab it continues to be seen with
Size: 129 GB ; Available: 125 GB ; Used: 4 GB
Do you think it is possible to make oVirt aware of the new available
storage space? Am I missing something obvious?
My setup is oVirt 3.4.0 RC2 with fully patched CentOS 6.5 hosts.
Best regards,
Giorgio.
