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 2) Go to Storage Pool 1. 3) Select "Global Settings" button at the top. 4) Adjust the "RAID Resync Speed Limits". See the note: "This setting will affect the speed limit when running data scrubbing, repairing, expanding storage pools, and changing RAID types." 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. Why speed up Linux software RAID rebuilding and re-syncing?

I've been looking in the RAID resync limits section and I notice 3 options: Lower the impact on overall system performance. Run RAID resync faster. Customize. Right now I've got "Run RAID resync faster" selected, and in resource monitor I see the 3 old drives reading at 80MBps and all 4 are writing at 50MBPs. 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). 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. 3TlB.
