jsteck Posted June 11, 2023 Share Posted June 11, 2023 (edited) Good evening, everyone! I don't know what I did but my cache doesn't work anymore! In the Share tab I have my folders with the cache activate! The cache runs slowly! speed and as fast as array (=180mo/sec) whereas before it could go up to 900mo/sec. How can I test my 2 nvme.m2 If anyone has an idea ! thank you in advance. Edited June 11, 2023 by jsteck Quote Link to comment

JorgeB Posted June 12, 2023 Share Posted June 12, 2023 Tell us the name of the share you are using and grab new diags in the middle of a large file transfer. Quote Link to comment
jsteck Posted June 12, 2023 Author Share Posted June 12, 2023 I move from my PC the Rain Man files to the folder Media / Videos/ (_films 4k_)Thanks again tower-diagnostics-20230612-1513.zip Quote Link to comment
JorgeB Posted June 12, 2023 Share Posted June 12, 2023 Looks like the transfer is going to the array, at least there's no pool activity and there is for the array, change that share temporarily to cache=only, do another transfer, is it the same or not? Quote Link to comment
jsteck Posted June 12, 2023 Author Share Posted June 12, 2023 (edited) so I cached only and the speed of transfer between Windows and unraid has not changed .but there is an amazing thing transfers it on unraid remains at zero for a few seconds and goes up to 1.4gb for 2 seconds then goes down to zero five or six seconds and starts to go up quickly again very little time, I suspect the cache is dead. tower-diagnostics-20230612-2035.zip I change pc always in 10gbs it is a little faster I go up to 360mo / sec but there is always this funny phenomenon or the cache is not at constant speed on a unraid.

jsteck Posted June 13, 2023 Author Share Posted June 13, 2023 I tried the 2 NVMe in my PC so formatting and it goes up between 1GB/sec and 2GB/sec so it is not dead... There may have been a problem because once (I had started emptying the user0) I am new in unraid and I had thought that the user0 was a hacker (I was hacked a month and a half ago.... Biensure I stopped because I thought it was going to empty the whole array the error may come from here after put hacked I reset everything except the array Quote Link to comment
