Hi,
I have a SLES 15SP3 running 5.3.18-150300.59.60-default. I have a nvme devices provisioned from DELL EMC Powerstore. I’m using native nvme multipathing in my host. I have released space through fstrim cmd. Though the command running fine, but I dont see space getting released on array end. I waited for hrs, no luck.
In the logs, I noticed this:
blk_update_request: operation not supported error, dev nvme0c1n1, sector 1056768 op 0x3:(DISCARD) flags 0x2000800

Is there any nvme-cli cmd to release space?
