hi, I am trying to rsync a very large filesystem which is about 3TB, but naturally I want to exclude a lot of things. However, I am really struggling with excluding directories. SRC=/dasd/december/2008 #Notice there is no trailing slash TARGET=/backup/december/2008 #Notice there is no trailing slash I want to exclude /dasd/december/2008/Data /dasd/december/2008/Logs /dasd/december/2008/Catalogs #NOTICE: I added a trailing slash for $SRC but nothing for $TARGET rsync --exclude Da...

The rules file, 51-by-id.rules contains details for the both of them, but the by-id do not get detected, at least the logs don't indicate so. The current contents of the rules file is as follows: KERNEL="dasd*[!0-9]", PROGRAM="/sbin/dasd_id", SYMLINK="disk/by-id/ccw-%c" KERNEL="dasd*[0-9]", PROGRAM="/sbin/dasd_id", SYMLINK="disk/by-id/ccw-%c-part%n" SYMLINK="disk/by-id/scsi-%c" SYMLINK="disk/by-id/scsi-%c-part%n" KERNEL="sd*...

As by the time, I've learned that Linux works by caching apps by using a lot of RAM and then it reallocates the new stuff by cleaning the old cached pages from memory as compared to other OSs. With 2 gigs of RAM often I see the free memory only as 100-400MB. Using TOP or PS, it doesn't look like any program or process is using excessive memory (the highest process is seen with 1-2% total

...n with vfio-pci, or also to plug in a faster device and use it instead of an already attached paravirtualized device? What about migration of vfio devices that are not easily replaced by a paravirtualized device? I'm thinking of vfio-ccw, where our main (and currently only) supported device is dasd (disks) -- which can do a lot of specialized things that virtio-blk does not support (and should not or even cannot support). Would it be more helpful to focus on generic migration support for vfio instead of going about it device by device? This network device approach already seems far along, so...

I found this forum posting but no responses http://www.centos.org/modules/newbb/viewtopic.php?topic_id=8714&forum=45 I am looking to perform a large migration of about 500 workstations from various Suse and Red Hat versions to CentOS to standardize some what.

Sir, How to run the rsync server in the remote machine. I want to mirror the set of directories from one machine to another machine which are in the network. I used the following command : /usr/sbin/rsync -vv --delete --recursive --times --perms --update source directory destinationmachine:destination directory. I got the error: Permission denied. How to tackle this error ? thanks laks
