Hello, all is fine with my containers running in Proxmox, but I have some OpenVZ HostNodes installed directly in CentOS 6, the bwlimit option don't take effect.

I run allways in snapshot mode.

Code:
vzdump --dumpdir /sata/vzdump --tmpdir /sata/vzdump --snapshot --compress --bwlimit [b]5120[/b] 100

Code:
vzdump --dumpdir /sata/vzdump --tmpdir /sata/vzdump --snapshot --compress --bwlimit [b]51200[/b] 100

In both, the result is the same: Total bytes written: 1659156480 (1.6GiB, 17MiB/s)
In the first, don't take care about the 5MB/s limit
In the second, don't get the performance specified.

Allways is around 15 MB/s

I can ensure that is not a issue on disk IO performance.

I've tested with many versions of vzdump (the vzdump 1.2-4, provided in OpenVZ repo and the one provided on the SolusVM repo), and same result with all.

Looking on the documentation, the vzdump is developed by @Dietmar, so, maybe you can help me to find the issue.

Thanks!!!
 
this is the support forum for Proxmox VE only. older vzdump releases are not maintained and if they are used on other distribution, its better to ask there for help.
