Modify Size failed #289

Hello,

today I tried to extend the volume size from 10GB to 20GB.

So I used:

gluster-block modify rdxarchive_2020/block-volume size 20GiB

Which failed, as you can also see here:

On all other nodes, tcmu-runner will not start since the modification:

Jul 08 22:33:04 fra1-glusterfs-m02 tcmu-runner[3446]: tcmu_glfs_open:519 glfs/block-volume: device size and backing size disagree: device 10737418240 backing 21474836480

Any idea why this happend and what I can do?

A reload and run the command again does not help. Also restarting the nodes not work.

Thanks!

Fixed by updating tcmu-runner to version 1.5.4.3 and rerun the modify command.
