Why speed up Linux software RAID rebuilding and re-syncing? Recently, I build a small NAS server running Linux for one my client with 5 x 2TB disks in RAID 6 configuration for all in one backup server for Linux, Mac OS X, and Windows XP/Vista/7/10 client computers. BakeCityWay • 3 yr. ago Impact is referring to your overall NAS performance. Everything will b slow when you run the resync faster or you can choose to have a slower rebuild but better performance while you use the NAS. r/synology News, discussion, and community support for Synology devices A community to discuss Synology NAS and networking devices Synology Knowledge Center offers comprehensive support, providing answers to frequently asked questions, troubleshooting steps, software tutorials, and all the technical documentation you may need. Adjust the RAID Resync Speed Limits | DSM - Synology Knowledge Center Nov 16, 2010 hi synology, is there something on the roadmap, that its possible to set the maximal rsync bandwith to use for network backup? this will be a nice features, if limited bandwiths are available and no QoS functions can be used. i need the feature in the GUI to set this : --bwlimit=500 To set the RAID resync speeds back to the default (recommended) speed via SSH as root: echo 10000 > /proc/sys/dev/raid/speed_limit_min. echo 600000 > /proc/sys/dev/raid/speed_limit_max Bei dem Speedlimit, könnte man auch fast schon eine Neuinstallation ins Auge fassen. sysctl -w dev.raid.speed_limit_min=100000 sysctl -w dev.raid.speed_limit_max=2000000 Mit diesen Befehlen hebt ihr das Min und Max Limit an und kommt nun auf eine viel größere Rebuild Geschwindigkeit. .
