Snuups Posted August 21, 2020 Share Posted August 21, 2020 (edited) Hi All Since 2 days I have a strange Problem when working with 2 clients. I copy massively much data into unraid with one computer. When I do something with the other one often suddenly all shares disappear and are not mounted anymore. Is there an explanation to this and can I do something about it? unraid-diagnostics-20200821-1257.zip Edited August 21, 2020 by Snuups Quote Link to comment
JorgeB Posted August 21, 2020 Share Posted August 21, 2020 Please set the DHCP leasing time to a much larger value, like a day or so, or it keeps spamming the log every 5 minutes making it much harder to look for other issues: Aug 21 03:05:16 Unraid dhcpcd[2099]: eth1: leased 10.0.10.112 for 300 seconds Quote Link to comment
Snuups Posted August 21, 2020 Author Share Posted August 21, 2020 I am searching quite a bit to change that. Is there even the possibility to change that? If yes, where? I have a UDM Pro Quote Link to comment

Snuups Posted August 21, 2020 Author Share Posted August 21, 2020 So far no luck. I guess it's not possible to change the lease time. In the Search in UDM Pro I type lease and no hits. So there is noch Setting for that. Quote Link to comment

I have a UDM Pro I have a USG router and, believe it or not, there is still no way to specify a DHCP lease time in the GUI. I could do it via CLI, but, that just seems cumbersome and not worth the effort. I am not familiar with the UDM controller. I stayed away from the UDM precisely because it cannot be adopted into an existing controller and must use its own built-in controller. That controller is probably based somewhat on UniFi so I assume you also cannot set DHCP lease time in any way other than through the CLI (if that is even possible on the UDM). My solution was to set static IP addresses on my most used devices. Otherwise, I think the default DHCP lease (at least in UniFi/USG) is 1 day. To see lease expiration time I had to login into the USG directly as it does not display in the controller. If the UDM controller is anything like the UniFi controller you go to the Clients tab, select the client, select Settings, expand Network and then set a fixed IP address (basically a permanent DHCP lease) for the client.

Snuups Posted August 22, 2020 Author Share Posted August 22, 2020 Well all this does not really help that my unRAID kills the connection when I upload some TB to it. All others can't work with unRAID then. Quote Link to comment
Squid Posted August 22, 2020 Share Posted August 22, 2020 Are you doing anything with regards to spin down of the SAS drives? I keep seeing this within the logs. Aug 20 21:18:41 Unraid kernel: sdj: detected capacity change from 7999366103040 to 0 The way that I understand it is that not all of the "hacks" to spin down SAS drives here are 100% safe under all circumstances. Disable spin down of the SAS drives in Settings - Disk Settings. Quote Link to comment
Snuups Posted August 22, 2020 Author Share Posted August 22, 2020 (edited) I'll try that Nope. No difference. I copy many files and large amount onto unRAID. All other actions fail or are super slow and probably fail. Like opening a .jpg is not possible. (With another Computer) Edited August 22, 2020 by Snuups Quote Link to comment
