Slow terminal response Centos 7.7 1908
Hey! I have a strange condition in one of the servers that I don't where to start looking. I login to the server via SSH (cant doit any other way) and anything that I type is slow HTTP sessions timeout waiting for screen redraw. So, the server is acting "slow". server is bare metal. no virtual services. no alarms in the disk raid note: server was restarted because of power failure.

Understanding VDO vs ZFS
Folks I'm looking for a solution for backups because ZFS has failed on me too many times. In my environment, I have a large amount of data (around 2tb) that I periodically back up. I keep the last 5 "snapshots". I use rsync so that when I overwrite the oldest backup, most of the data is already there and the backup completes quickly, because only a small number of files have

File server as host for a Windows Server VM?
I did that kind of in the past. Now I dont because I have plenty of resoruces available. But. So far you have not provided stats on server usage (cpu,ram) over a 24hour or 7 day 8am-5pm timeframe. So I will asume you have plenty of usage/performance to spare. I suggest you to -if possible- replicate the current server setup somewhere else and then install the KVM and dependencies via yum. That way

Hi all, I would like to record user commands in terminal mode for remote supporters. I currently do that with the command "script - make typescript of terminal session".

CentOS 8 on USB disk
That happened to me several times My USB was "burned" and never displayed new data copied to it. By "burned" I mean the flash drive was faulty up to a point where it always showed a phantom image of what WAS in the pen drive.

Understanding VDO vs ZFS
My two cents: 1- Do you have an encrypted filesystem on top of VDO? If yes, you will see no benefit from dedupe. 2- can you post the stats of vdostats ?verbose /dev/mapper/xxxxx (replace with your device) you can do something like: "vdostats -verbose /dev/mapper/xxxxxxxx | grep -B6 'save percentage' On Sat, May 2, 2020 at 9:54 PM david <david at daku.org> wrote: >

Opinions on storage options such as gateways or like-systems
Hi all, I'm looking for some comments regarding options related to storage.

When the Apache/MySQL R/W data, Data storage is provided as a single NFS volume mounted across the VMs. That storage space is
