I would suspect that some of the source files are "sparse." Ie. there are "holes" in the middle of them where space hasn't been allocated in the source directory. Some applications that use random file access will create sparse files. A simple copy operation that doesn't look for sparse files will fill in the holes, causing the copy to take up more space than the original. I haven't tried it (at least not recently), but rsync appears to have a "--sparse" (-S) option. Try using that in addition to -av and see if that changes the results. GNU tar has a similar option. -dpm -----Original Message----- From: Michael Mansour [mailto:micoots@xxxxxxxxx] Sent: Tuesday, May 25, 2004 11:45 PM To: fedora-list@xxxxxxxxxx Subject: rsyncing 79gb of data to 250gb drive Hi, I have an issue which I can't seem to figure out. I bought a 250Gb Maxtor Maxline Plus ATA133 drive, plugged it into a server, formatted it using: # e2fsck -m 0 -j -b 1024 /dev/hdc1 I made the partition a Linux partition id 82. After format, 241Gb free space is recognised. I have 80Gb of data on another drive in the system that I wish to backup onto this drive. So after rsyncing the drives contents from the 79Gb (which is on a stripe) to the maxtor 250Gb drive, the following is the result: /dev/md6 85419328 79573952 1506236 99% /data01 /dev/hdc1 241201359 123508888 117692471 52% /data02 123Gb used??? this is what is confusing me, why? I first formatted this drive using 4096 block size and got the result above, then I thought I'll reformat it and change it to 1024 byte block size to try and get back some space, the same result above. I've also made sure (with tune2fs) that the "sparse" option is turned on for the large filesystem. I thought maybe the rsync was following symlinks (which I'm sure there are none), but by default the command: rsync -av won't do that. I checked for pipe and socket files using find, and also couldn't see anything suspicious. I'm at a loss to figure this one out and thought I'd email here for some help. Thanks. Michael.
