Hi to all
Anyone can help me?
On PVE, for Linux and Windows systems and only with KVM, I want HA-Failover without data loss with the best performance on each virtual HDD and his partitions, and if my Host/VM hang up without have configurated HA.
notes:
A- All questions are based on HA-Failover without data loss with the best performance on each virtual HDD and his partitions, and if my Host/VM hang up without have configurated HA.
B- I see on the link http://pve.proxmox.com/wiki/Performance_Tweaks that cache=none is the best performace.
C- I use the drivers of virtio-win-0.1-30.iso for Windows systems (It is the latest version for now)
D- In case of HA, I use DRBD protocol C and with tunning.
Questions:
1- For Linux with Kernel < 2.6.37, I only need to add the option "barrier=1" into fstab right?
2- About above, is the same configuration for each line of configuration into fstab? - for example for swap partition and others partitions ext3?
3- If I have Linux kernel < 2.6.37 and ext4 partition, do I need to add this option?
4- For Windows systems, what is the better configuration for the best performance without data loss? - his wiki don't said anything about it.
Please answer considering that in some cases I can have or not raid controller with cache with battery.
Best regards
Cesar
