Hello friends I am SysAdmin at the Agrarian University of Havana, Cuba.
I have installed Proxmox v3.4 here a cluster of seven nodes and for some days I am having problems with a node in the cluster which only has a Container with Zimbra 8. The problem is I'm having a lot of I / O Delay and that server is very slow to the point that sometimes the service is down. The server is PowerEdge T320 Dell with Intel Xeon E5-2420 12gram with 12 cores and 1GB of disk 7200RPM 2xHDD are configured as RAID1. I have virtualizing the zimbra 8 using a template of 12.04, has 8 cores, 8G RAM, 500GHD the storage of container is local storage. Then I put the output to see the IO when you are not running the VM. Look at the BUFFERED READS that are marked are very bad. And those moments have seen IO Delay up to 50%. root@n07:~# pveperf CPU BOGOMIPS: 45601.20 REGEX/SECOND: 1025079 HD SIZE: 9.84 GB (/dev/mapper/pve-root) BUFFERED READS: 1.51 MB/sec AVERAGE SEEK TIME: 165.88 ms FSYNCS/SECOND: 0.40 DNS EXT: 206.20 ms DNS INT: 0.91 ms (unah.edu.cu) root@n07:~# pveperf CPU BOGOMIPS: 45601.20 REGEX/SECOND: 1048361 HD SIZE: 9.84 GB (/dev/mapper/pve-root) BUFFERED READS: 0.78 MB/sec AVERAGE SEEK TIME: 283.84 ms FSYNCS/SECOND: 0.50 DNS EXT: 206.13 ms DNS INT: 0.89 ms (unah.edu.cu) root@n07:~# pveperf (Este fue cuando detuve la VM) CPU BOGOMIPS: 45601.20 REGEX/SECOND: 1073712 HD SIZE: 9.84 GB (/dev/mapper/pve-root) BUFFERED READS: 113.04 MB/sec AVERAGE SEEK TIME: 13.49 ms FSYNCS/SECOND: 9.66 DNS EXT: 198.59 ms DNS INT: 0.86 ms (unah.edu.cu) root@n07:~# pveperf CPU BOGOMIPS: 45601.20 REGEX/SECOND: 1024213 HD SIZE: 9.84 GB (/dev/mapper/pve-root) BUFFERED READS: 164.30 MB/sec AVERAGE SEEK TIME: 13.61 ms FSYNCS/SECOND: 16.34 DNS EXT: 234.75 ms DNS INT: 0.94 ms (unah.edu.cu) Please help me.
