Question
I have resized the LUN for my Data Store which is using ISCSI, so how do I make OnApp reflect this?
Environment
All OnApp Versions
LVM Datastore
Answer
First, run the following ISCSI rescan on one HV:
iscsiadm -m node -R
Find the name of your SAN device and compare its size with the size of your LUN:
fdisk -l
Followed by the pvresize for the correct disk that has been resized:
(if you use multipath, you should reload (or restart) it before pvresize)
pvresize -v /dev/xxx
pvscan
Then, log into all other HVs and run:
iscsiadm -m node -R
pvscan
You will also need to edit the data store in OnApp to show the new size:
(Settings > Data Stores > Edit)
