Re: [Xen-users] lvm size

[Anand <xen.mails@xxxxxxxxx>]

If i have two volumes test7 and test8. What is most efficient way to copy data from one to another ?

I did tests using cat, rsync, dd, cpio and all of them seem to be consuming almost all of my dom0 256MB ram and cpu load goes up to a max 
1.65 (athlon 2.6ghz, 1gb ram)

Infact dd takes more time to copy the data, ofcourse the reason being the way it operates and copies sector by sector. All other tools averaged time at 4.5 mins, dd took 6+mins.

The test7 volume is of 850MB and the test8 volume is of 1GB. The test7 volume is actually the template for the centos which is used for various domains.

Can anyone please share their experiences on what they use to copy data most efficiently ?
