Growing an online TrueNAS filesystem requires iSCSI Refresh support

I am trying to grow a TrueNAS storage filesystem volume.

$ incus storage volume set slownas s3 size 1536GB
Error: Growing an online TrueNAS filesystem requires iSCSI Refresh support. Please update the TrueNAS tool: In use

How to interpret this message? How to grow it safely?

  • TrueNAS version: 25.10.1 - Goldeye
  • Incus 6.21
  • truenas_incus_ctl version 0.7.4

Looks like the code requires 0.7.5 or higher for this feature to be supported.

I see, so I resolved it by switching off the container and extending the filesystem when the container was offline. All went good. Thanks!
