Are you doing a file or full array rebalance? Are there a few large files that are not balancing? Are there snapshots? What is the output of the following commands? isi job reports list --job-type=autobalance
When was the last time a collect job or multiscan had run on this cluster? One node can pick up larger amount of capacity if it had gone to a readonly or offline state in past and if collect or MultiScan has not run. I ll start with collect. Mind you , its a job that takes time. Cheers,
I can finally confirm that the problem is solved. Took some time to find the root cause, but now it seems to be fine and cluster is slowly balancing.
Apparently that particular node worked ~2 years with just a single 40gbit external interface up. The other one was down due to issue with the DAC fiber cable. I believe this caused the node not balance and just fill up slowly over time.
After fixing that I ran Multiscan and Autobalance, but the cluster started actually balancing after starting the AutobalanceLin job. Now the node is at 78% and decreasing. Also the disks inside that node are quite busy at 99% while the job is Running.

Hi,
Thanks for your question.
Are you doing a file or full array rebalance? Are there a few large files that are not balancing? Are there snapshots? What is the output of the following commands? isi job reports list --job-type=autobalance
isi job reports list --job-type=autobalancelin
Let us know if you have any additional questions.

Alright. Thank guys.
I can finally confirm that the problem is solved. Took some time to find the root cause, but now it seems to be fine and cluster is slowly balancing.
