Whats the correct way to resize iscsi gfs2 datastores?

[BMuellerDSR]

Hi to all,

whats the correct way to resize an shared iscsi gfs2 datastore?

What I did:

Resized the iscsi volume at the storage system

Rescan iscsi targets on one host (after Resize)

iscsiadm -m node -R

sudo systemctl restart multipathd

gfs2_grow /mnt/7e2728f1-47de-4832-8893-2ac90e7c9451

On all other Hosts

iscsiadm -m node -R

sudo systemctl restart multipathd

After that all hosts now show the volume with the right new size via LSBLK

(I grew the gfs2 volume from 60GB to 90GB)

But on the webif of vmemgr it shows complete nonsense, Two hours it showed a datastore size of 2.1MB!

After Restart of the vmemgr and all three hosts it is showing a new size of 67GiB (more than 60GiB but much less than 90GiB) how to get the system to show the right size? And whats the right way to grow gfs2 datastores?

Thank You.
