I noticed an issue with my rsync speeds to my RAIDZ2 pool. I typically would've gotten 50MB/s but now I can barely write more than single MBps. My pool is nearly 100% capacity so I expected some performance degradation but I still have 150GBs of free space and not for my performance to fall into KBps territory. Logs have not shown me anything. Is there anything else I should check? I suspected a faulty HBA or some bad disks but I've not seen any issues anywhere.
