RAID storage for archive data storage solutions RAID is n 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 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." Sprawdź listę zgodności produktów Synology, aby zobaczyć, które dyski są zgodne z urządzeniem Synology. Kalkulator RAID Synology zapewnia szacunkowe zużycie pamięci masowej dla konfiguracjami dysków mieszanych i RAID. Systemy Synology wymagają około 10 GB miejsca do wykorzystania w konfiguracjach RAID 1. 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? 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 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. 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. Just go to the Configuration, and change the RAID Resync Speed Limits to "Run RAID resync faster". So, what it does is… it raised the Min speed limit from 10MB/s to 300MB/s. And I can see the speed actually much faster once I did this. G6MGntD.
