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. 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. 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? 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.
