Hi,
I need some help for the decision what caching option is the best for us.
Very important is, that data loose is not possible.
After read https://pve.proxmox.com/wiki/Performance_Tweaks
the most secure way is to use cache=writethrough. Isn't it?
Our setup is:
LSI 9211-i8 in IT mode (no Cache)
Samsung 840 Pro for OSD's formatted with XFS and mounted with rw,noatime,attr2,discard,inode64,logbufs=8,logbsize=256k,noquota
VM Harddisk Type: SCSI (VIRTIO) with discard option
At the moment we use cache=writeback. But is it safe??
Thank you for help.
Regards
