I'm running such a setup since about 4 month without any problem so far, on 
Cisco UCS Blades.

Is it a viable solution? there is somewhere some tuto about tuning ovirt on

Re: [ovirt-users] ovirt on sdcard?

2017-07-20 Thread FERNANDO FREDIANI
The proposed seems to be something interesting but is manual and 
susceptible to errors. I would much rather if this would come out of the 
box as it is VMware ESXi.


A 'squashfs' type of image boots up and runs completely in memory. Any 
logging is written and rotated also in memory which keeps only a certain 
recent period of logs necessary for quick trobleshooting. Whoever wants 
more than that can easily set a rsyslog server to collect and keep the 
logs for a longer period. With this, only the modified Node 
configuration is written in the SD Card/USB Stick when it changes which 
is not often which makes it a reliable solution.


I personally have a Linux + libvirt solution installed and running in a 
USB Stick that does exactlly this (writes up all the logs in memory) and 
it has been running for 3+ years without any issues.

Perhaps provide some more details about your plans?

The local disk is normally used only for standard OS-level stuff -
mostly logging. If you put /var/log on NFS/iSCSI/whatever, I think
you should not expect much other local writing.
Didn't test this myself.

People are doing many other things, including putting all of the
root filesystem on remote storage. There are many options, depending
on your hardware, your existing infrastructure, etc.

Best,


Thanks

[ovirt-users] ovirt on sdcard?
