I have a HP Microserver Gen 8 with 8 Gb RAM running OMV 2 Stone Burner for years. I planned to upgrade to OMV5 during christmas's holiday with a new fresh installation, temporary removing data disks.
Now I have OMV installed on SSD in ODD port, booting from an old USB stick installed on internal port but I want to change this config due to difficult and unstandard boot mode. To use the large part of 128Gb SSD as Data Disk (to run VM and Docker in the future) I have used GParted to split into 2 partition.
To avoid USB boot and installation on different disk, i initially think to activate HW Raid on ODD port (on Bios) to make boot from SSD avaible. With this config I have to manually resize partition yet, and this is not good for future update.
So I think to change all the config:
- remove old internal USB stick
- buy 16 GB USB 3.0 and mount it on rear USB 3.0 port
- install OMV in the USB
- install flash memory plugin (Is it still avaible on OMV5?)
- leave the SSD as data disk, to use with Docker container
Is it ok? With this config I think that upgrade will be easier (no unstandard boot mode and no losses of SSD Data in new installation ...)
Is it better to use USB2.0? I've read problems booting from USB3 ...
Is there performance's problems running on USB3? Is it evident slower than actual config? And on USB2?
Thanks in advice ...
