We seem to have performance problem with freenas to the point were it is causing data corruption.
Anyone already encountered those kind of problems.
iSCSI has its own dedicated 10Gb network and we have only 2 backup servers using it. Backup servers are doing a good amount of random iops because of deduplication in the backup solutions but mostly sequential writes. The backup servers are both running Windows Server 2016. Jumbo frame is already configured and we can reach nearly 900MB/s on reads but writes are really slow.
Freenas server config;
{Delayed Write Failed} Windows was unable to save all the data for the file <path>; the data has been lost. This error was returned by the server on which the file exists. Please try to save this file elsewhere.
