Same with 2.6.17-1.2187_FC5 So does 2.6.9... [root@aluminium ~]# mount /dev/hda7 /mnt/test [root@aluminium ~]# mount /dev/hda7 /mnt/test2 [root@aluminium ~]# uname -a Linux aluminium.msp.redhat.com 2.6.9-42.EL #1 Wed Jul 12 23:16:43 EDT 2006 i686 i686 i386 GNU/Linux [root@aluminium ~]# mount | grep hda7 /dev/hda7 on /mnt/test type ext3 (rw) /dev/hda7 on /mnt/test2 type ext3 (rw) And it can be done with any other fileystem too. but there's nothing wrong with that... why do you think this is a bug? Sorry, you're right. I've to refresh my old knowledge of linux. It's possible since 2.4. The mount(2) man page: Since Linux 2.4 a single filesystem can be visible at multiple mount points, and multiple mounts can be stacked on the same mount point. |
Description of problem: With a current FC-development machine, I can mount a ext3 filesystem read-write twice without getting any warning or error message from the kernel: mount /dev/sda1 /data1 mount /dev/sda1 /data2 Is this check up to the (l)user requesting this or should the kernel return EBUSY for this case? regards, Florian La Roche Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3.
