Hi,
my hardware is:
- HP ProLiant DL370 G6 with 24x 2,5" hot swap bays (3 backplanes)
- these backplanes are connected to an HP SAS Expander Card
- the Expander Card is connected to an Avago SAS 9211-8i HBA
- 22x HP SAS HDDs (300 GB, 10k rpm)
- these HDDs are organized as a raid10 via mdadm: /dev/md1
- /dev/md1 is configured as a physical volume and a volume group (vg1) inside - which Proxmox uses for storing vm disk images
For testing purposes I created a logical volume called pveperftest, formatted it as ext4 and mounted it to /mnt.
Finally I ran pveperf:
BUFFERED READS looks good, but FSYNCS/SECONDS looks bad, doesn't it?
What can I do to improve this?
My Proxmox ist up to date from the subscription repository:
The initial setup I did with a Debian installation, not with the Proxmox-ISO.
Thank you very much and greets
Stephan
