Dear Robinhood users and developers,
I've encountered another thing: sparse files. When scanning a NFS filesystem
I've found a file reported to have 2TB size by rbh-report. It was a sparse
file though, not a real 2TB one:
[root@myhost]# stat
myfilename
File:
`myfilename'
Size: 2196003979264Blocks: 337664 IO Block: 1048576 regular file
Device: 16h/22dInode: 3735378 Links: 1
Access: (0664/-rw-rw-r--) Uid: (100101/myuser) Gid: (100101/myuser)
Access: 2014-02-19 22:06:37.128304863 -0600
Modify: 2012-10-04 16:29:00.000000000 -0500
Change: 2014-01-03 16:36:32.369687879 -0600
[root@myhost]# du -s –m myfile
myfile
165myfile
How does Robinhood report/collect the file usage data? Does it go by "Size:" in
stat, or by 512*"Blocks"? Results can be vastly different for the individual
files as this example shows. Is the overall filesystem usage counted by the
nominal sizes or used blocks? Is there any scan/report options to chose one way
over another?
Thanks!
