ukkeman Posted January 15, 2022 Author Share Posted January 15, 2022 Speed to windows vms is at full. Write speed to cache array is at 500mb/s Quote Link to comment
ukkeman Posted January 15, 2022 Author Share Posted January 15, 2022 I can see it's writing on to the cache but the way it's writing is odd in the dashboard. The speed is shown as zero then for a brief moment goes to 300mb/s and then drops to zero again. Quote Link to comment
Squid Posted January 15, 2022 Share Posted January 15, 2022 If you've made changes to the use cache setting use Dec 8, then they won't take effect until a stop / start of the array (known issue on RC2) Quote Link to comment
ukkeman Posted January 16, 2022 Author Share Posted January 16, 2022 No I did not the settings are there since a very long time and since I restarted the machine and the array several times. So I don't think this is an issue. I also can see that smb transfer writes to the cache disks when I look at the dashboard and directly on the mounted disks. I also can not see any significant things like maxed out CPU or oom in tools like netdata. This drives me a bit crazy. There is no encryption of the disks but if that'd be the bottle neck I would also see a higher CPU load Quote Link to comment
ukkeman Posted January 20, 2022 Author Share Posted January 20, 2022 I tried to create a new share with cache only. Restarted the array. Got the same speed around 30MB/s Quote Link to comment
ukkeman Posted January 24, 2022 Author Share Posted January 24, 2022 Tested it with GBIT Lan now: SMB: 45 MB/s SCP: 110 MB/s to the same share. Used in both cases the mnt/User path and not any direct disk share path. Quote Link to comment
