@sumsum

I got the battery, must I wait the charging or can I activate the cache right now ?

When batteries are fully charged your cache should be enabled.

Btw. your cache ratio seems weird. You have 0% Read / 100% Write I would expect something like 50% < Read < 75%

OK, I made a quick and dirty testscript...


Code:
#!/bin/bash


rm -rf tune-hp-server.txt


for i in $(seq 5 10 100)
do
        k=`expr 100 - $i`

        hpacucli ctrl slot=0 modify cacheratio=$i/$k >> tune-hp-server.txt

        echo "--------------------------------------------------------------------------------------------" >> tune-hp-server.txt

        hpacucli ctrl all show detail >> tune-hp-server.txt

        echo "--------------------------------------------------------------------------------------------" >> tune-hp-server.txt

        pveperf  >> tune-hp-server.txt

        echo "--------------------------------------------------------------------------------------------" >> tune-hp-server.txt
        echo "--------------------------------------------------------------------------------------------" >> tune-hp-server.txt

done


exit 0




Please take a look on it and give me a hint, I like to use two win7 clients with ms-sql-db and one linux fileserver (sme8).

your fsync is much improved so now we can look at other issues.

1) What file system is on /var/lib/vz?
2) What are the mount options on /var/lib/vz?

Yes, I made a 2nd Guest with only 500GB hdd, this works just normal but the 1TB Guest is still not working ???

I think I should build a 3rd with 1TB and test the qmrestore again ?
