Run RAID resync faster. /proc/sys/dev/raid/speed_limit_max= 600000. /proc/sys/dev/raid/speed_limit_min= 300000. As for /sys/block/md2/md/stripe_cache_size(also used to speed up resync) I just checked for all three options and they all come back as 1024(same value as when I check on DSM 6.1.6).
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
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 Please follow the steps below to adjust the Resync speed: Go to the Storage page and click Global Settings. In the RAID Resync Speed Limits section, select one of the following speed limit options: Lower the impact on overall system performance (recommended): Select this option to lower the

When you go to Global Settings in Storage Manager, on Raid Resync Speed Limits, which option is selected? If "Lower the impact" it makes it much more variable. If you go for "Run RAID resync faster" it will mostly run as fast as possible, with a more noticeable impact on other processes.

This looks as though it only lets you change the speed_limit_min and speed_limit_max values, but not the stripe_cache_size variable. Still, it'll be nice to be able to set this in DSM and not worry so much about it anymore. Is there any data on what the "Run RAID resync faster" radio button actually changes?
Sep 2022. Hi There! Just wondering why the speed to change RAID Types is so slow I'm currently changing from SHR to SHR-2 on my RS2421+ and I have about 29GB of data. My CPU is usually around 1% utilization as per Performance Monitor and my DSM Desktop Read / Write is between 20MB - 30MB in Task Manager.
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 Sprawdź listę zgodności produktów Synology, aby zobaczyć, które dyski są zgodne z urządzeniem Synology.
