From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.1) Gecko/20021003 Description of problem: After creating and mounting a RAM disk you can store files on it. After unmounting and then mounting the RAM disk again these files are gone. This used to work in other distributions and kernel versions. Note: the fact that this does not work in itself is not a problem since you should not use RAM disks for this but use shmfs instead. But I've got the feeling that this a more fundamental bug somewhere in the filesystem code, instead of a RAM disk bug. Hence the report. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: mkdir /mnt/ramdisk dd if=/dev/zero of=/dev/ram0 bs=1024k count=4 mke2fs /dev/ram0 (Note - the RAM disk is now 16 MB instead of 4 MB. Strange...) mount /dev/ram0 /mnt/ramdisk df (confirms that the FS size is 16 MB) cp /etc/passwd /mnt/ramdisk/passwd cat /mnt/ramdisk/passwd (no problem) umount /mnt/ramdisk mount /dev/ram0 /mnt/ramdisk (no problem so the filesystem info is still there!) cat /mnt/ramdisk/passwd (no such file or directory!) umount /mnt/ramdisk Actual Results: 1. Filesystem is 16 MB 2. /mnt/ramdisk/passwd: no such file or directory Expected Results: 1. Filesystem size should have been the size of the ramdisk - 4 MB 2. File should be there and viewable Additional info: This has always worked on 2.4 kernels and earlier. Does not work under the default FC2 kernel, and the problem has been confirmed under vanilla 2.6.6 as well.
Should not use the "back" button on my browser - this creates multiple bug reports... :-( *** This bug has been marked as a duplicate of 124904 ***
