There is one known bug with XFS. Apparently Mandrake grabbed one of the public XFS patches at precisely the wrong time when there was a bug in it. It is only present when running the enterprise kernel with XFS partitions that I know of. If you're using the regular or smp or secure kernels, it probably will work just fine. Blue skies...

Re: [expert] Mount problem on XFS partition
I think I certainly need some more help here. 1. You're not actually copying to the xfs filesystem, only to the directory /mnt/backup. Does this mean that there is some other step to be done after formatting an XFS partition? What does it mean writeing to a directory without copying to a filesystem ? 2. My /etc/fstab looks this way /dev/hda5 /mnt/backup xfs defaults 1 2 3. The disk is formatted but no filesystem is created. I've not played much with XFS, but on most other filesystems the formatting and creation of the actual filesystem are separate steps. How would I create a filesystem on the XFS formatted partition? 4. Your kernel does not support XFS or the module is not loaded. This would be unusual unless you've modified your kernel. I did not modify my kernel. I am running MDK 8.2 standard (download edition) 5. Thanks a lot for your help.

Look at the other programs in xfsprogs. You should also install these packages: xfsdump acl (this last one to manage ACLs, but keep in mind that other utilities --fileutils, tar--, aren't patched to support ACLs).

Re: [expert] Mount problem on XFS partition
On Wed, 20 Nov 2002, Stefano Pogliani wrote: What does it mean writeing to a directory without copying to a filesystem ? I see that Luca has answered your questions -- just elaborating a little here: A mount point is nothing more than an empty directory created by mkdir. When you mount a filesystem, whether on a HD, floppy, or CD, its hierarchy shows up under the mount point. Copying files to this mount point then copies files to the disk. If you unmount the filesystem then the directory is still there. For example, if you have a system setup in this way: / hda1 /home hda2 swap hda4 /home and /export are mounted filesystems under /. If you do an ls of /home, you'd see somethng like: drwx--6 klowelocal 401 Oct 7 21:51 klowe drwx--6 robert remote299 Feb 3 2001 robert drwx--6 wperez remote299 Feb 3 2001 wperez If you were then to unmount /home, ls would return nothing, *unless* you happen to have copied files there when the hda2 partition was unmounted. E.g.: $ mkdir /nothing $ touch /nothing/emptyfile $ ls /nothing emptyfile $ umount /home $ mount -t ext2 /dev/hda2 /nothing $ ls /nothing drwx--6 klowelocal 401 Oct 7 21:51 klowe drwx--6 robert remote299 Feb 3 2001 robert drwx--6 wperez remote299 Feb 3 2001 wperez In this example, emptyfile was create on the hda1 partition. The mount points do not need to be on the root filesystem. You can create mount points almost anywhere that has a real filesystem (i.e., probably not /proc -- though I admit I've never tried). So you could create a /home/external that's mounted on a separate disk. The mount point is created on hda2 in this example, but the mounted filesystem could be anywhere. This is what allows rescue disks to work. They boot up, create their own /, /usr, /lib, etc.., but then mount the damaged filesystems somewhere on their hierarchy.

[expert] Mount problem on XFS partition
I just tried today to create an XFS partition on a new hard drive. It was the first time I was playing with Journalized partitions, so I may have done something strange.
