I did mean glusterFS. Now I have a questions about the file system flags. Suppose a VServer that has four physical disks. /mnt/disk1 formatted ext3 /dev/hda1 /mnt/disk2 formatted ext3 /dev/hda2 /mnt/disk3 formatted ext3 /dev/hda3 /mnt/disk4 formatted ext3 /dev/hda4 If i built a vserver named test with a rootdirectory of /mnt/disk4, it would get installed to /mnt/disk4/test. The 'quota' would be the fact that test could fill up disk4. Question 1: The guest test is locked inside /mnt/disk4 The guest has no access to disk1, disk2, disk3. True or False? Question 2: If test2 was also installed to /mnt/disk4/test2 could that guest affect test1?
