High disk write

[Marius22]

Hello,

so i am having a issue with my VMs that die on on me and kills the processes the users are running, when there is a high disk write. so by time to time ( several times a day - times are random ) there will be a high disk write \ read on the disk and I am not sure how to identify the process all the VMs using that specific disk report something like this

1.



2.



So basically i am running a windows server and a NAS. And i cant figure out what process or vm is causing this and how can i avoid it.

Anyone can advice?

Thanks,

You could try atop or iotop to check what process is causing the IO.

does not help since it does not show from history and the data is crazy in iotop so many stuff writes in the same time and jumps up and down cant figure anything from there
