Acronis Disk Image cannot clone to the same storage SSD

I wanted to clone my computer.
My computer is using 450gb SSD.

I used Acronis disk image to clone the SDD to another new SSD (with same storage 450gb) but the new SSD cannot show in Acronis disk image software. (New SSD has already formatted)

I tried to use bigger storage HDD that is 1tb. This time, it successfully clone.
Why it cannot clone to the same storage SSD?

mysql – slow disk with InnoDB page compression

I have a write-intensive MariaDB with both NVMe SSD and HDD disks. I recently enabled page compression (innodb_compression_default=ON). I encountered two problems:

  1. The database gets slow after a while. INSERTs get noticeably slower after one day. When restarting the machine or MariaDB, it gets backs to normal speed.

  2. It takes a long time to shutdown MariaDB (~30 min). During this time, the SSDs have heavy disk activity (as checked by iostat). Note that it is not flushing the data into the disk. Before shutting down, the number of dirty pages is zero, and there is absolutely no activity in show engine innodb status G.

I think it might be due to the rearrangement of data on the SSD drives (about 50% full). Some sort of activity like SSD TRIM.

How can I diagnose the underlying causes?

nfs – Google Cloud Filestore, How to limit the disk usage of each user directory?

I’m currently using Google Cloud Filestore to store user data. Each user has a separate directory, in which they can store any data they want.

However, as the users grow, the capacity cannot handle all the uploaded files. Therefore, I want to set the usage limit of each directory (for example, /my_filestore/alex can only store up to 10GB).

At first, I plan to use quota utility tool, but this tool cannot work with NFS mounting, as NFS.mount does not allow usrquota option.

Is there any other alternative to do implement this restriction? Thanks so much.

OpenVPN Disk I/O – Server Fault

I’ve asked on the bona fide OpenVPN forum but no response. Whenever I connect to an OpenVPN server using OpenVPN client on Microsoft Windows, it immediately starts writing to disk at about 300k/s sustained throughout my session judging by the Microsoft Performance Monitor. It seems that it is recording my session. Is this to be expected and can it be turned off ?

windows – Is there a reliable way, via powershell, to detect if a user has been logged on with a temporary User Profile Disk?

I am migrating my users from a Server 2012 R2 farm using Roaming Profiles to a Server 2019 RDS deployment using User Profile Disks. I have created a script that will copy the “important” folders from the UNC where the roaming profile is stored into the user’s new UPD, and have deployed that script via GPO as an immediate schedule task that only is created if a particular “Profile migrated” flag is non-existent (which the script obviously creates).

It is works very well under “normal” circumstances.

But, if a user happens to log on and their UPD is locked (an admin user primarily, who has the rights to log into multiple session host servers at once, and knows that this might happen under those conditions) and they get assigned a temporary profile/UPD, I want to detect that and NOT run the script.

I have not found a reliable way that I can check to see if the current session is using a temporary profile that I can use in “Item Level Targeting” to further filter and prevent this scheduled task from being created if the user is running under said condition.

Any suggestions? Registry settings seem to be the most likely candidate, but I haven’t found one that works yet.

performance – Monitor disk activity by process and by file in linux like windows ressource monitor

I have multiple disks in my system sometimes I have a heavy read usage on my root partition. I know that there are some processes reading a lot of data, but from all disks. How can I find out which process is accessing which file?

I’ve tried htop, dstat or iotop. However these seem not to be able to show activity by process and file. In windows ressource monitor does this job perfect:

enter image description here

I can’t imagine that there isn’t a similar console tool for linux.

big sur – How to setup Disk Quotas on macOS Big Sur?

You would need to install quota-tools from Homebrew and then use that to configure your disk quotas.

Install Homebrew (if you haven’t done so already)

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Then install quota-tools.

brew install quota-tools

Afterwards edit your /etc/fstab to enable disk quotas for the file sytem

/dev/rdisk0 /home apfs defaults,usrquota 0 2

Then run edquota to add disk quotas for the individual users:

sudo edquota -p user1 user2

After that restart the system to have the disk remounted and disk quota to take effect.
