RN31400 iSCSI Sync Writes
Hi... I've refreshed the ReadyNAS disks and upgraded firmware (Factory reset to 6.7.4). I use the ReadyNAS to store active SQL and mail databases, images and disk based backups via iSCSI. I have plenty of disk space 13 TB free and 1TB free on the iSCSI LUN where data transmits over a 10g pipe. Backups, Shapshots and large archive transfers (40Gb to 500Gb) were running great before firmware 6.7.4 when you were allowed to disable sync writes and have access to iSCSI disk. Not so much with 6.7.4. What options do I have ot overcome the backup, shapshot and file transfer failure. - Increase MTU to 3000 or even 5000? - Is there an override to allow desabling sync writes and have access to iSCSI (current running is Microsoft 2.08)? - Reduce the busy disk time with sync writes? The Volume throughput was never this busys with 6.6.x Data reads LAST: 961.3m AVG: 36.1 MAX: 109.7, MIN: 0.0 Data writes LAST 433.7, AVG: 171.2, MAX 447.2, MION: 0.0 - Upgrade to 6.7.5 Thanks, AdrianSolved5.4KViews0likes5Comments
