Hello I am currently testing PVFS version 2.8.1.
I found installation very simple and I now have a single server and a single client for testing. One of my requirements is that sparse files are handled properly. We use these for virtual machine images. I've found that the writing of sparse files is handled correctly. For example, I use the QEMU image create tool: qemu-img create test.img 5G That will create an raw image of 5G size. I have verified that the space is not being fully allocated on the PVFS server. So the writing of the file is being handled correctly. However, reads are not handled correctly on the client. For example, the "du" command can not calculate the actual disk space used. Tar does not see the sparse bit of the file either when running with the -S option. Is this a limitation of PVFS or can I configure it to handle sparse files properly. Thank you. _______________________________________________ Pvfs2-users mailing list [email protected] http://www.beowulf-underground.org/mailman/listinfo/pvfs2-users
