What is the Best Synology RAID and why do I need it? RAID storage for archive data storage solutions RAID is n 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. 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 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? In my own experience with Synology and other raid controllers on Windows, it takes about 12-13 hours to rebuild a 2Tb drive and about the double for a 4Tb drive. So in your case, it would take around 2 days for the rebuild of a 8Tb drive. Seems like this how fast the hardware can work these days.

Adjust the RAID Resync Speed Limits | DSM - Synology Knowledge Center what are the max speed limits for the custom RAID Resync Speed Limits? Whats a good way to test these out? How would I notice the I have gone over the edge? 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. 1 Likes Hi everyone, I have a DS916+ running DSM 7.0. I just spend almost 24h for data scrubbing to run on the new 2x 18tb drives in Raid1 with no data on them. While this was happening the CPU was at 0% all the time and I was not doing anything else on the NAS. The process is just as slow on another identical NAS running DSM6 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 4SoUi.
