can we merge two separate filesystems,
stored for example on /dev/hda1 and /dev/hda2, and we want to combine
the data in the two filesystems into a single filesystem /dev/hda3, or
combining the contents of /dev/hda2 so that it is also in /dev/hda1.which could be highly efficient for administrator managing several file systems
So is there any mechanism exist to do so either online or offline.If not can any one suggest something.
thank you
combine
how do you want it combined? mount, unionfs, symlinks, raid, cow snapshot? does it have to be distinct partitions or can you live with single filesystem features?
Merge
What I wanted was to somehow merge the two File systems.I was thinking of manipulating the information of superblock and then merging the data blocks of inode for ext2 but i not too sure about my design.
secondly i thought to incorporate LVM but still stuck .
Plz help !
thank you
there is no such feature in any filesystem I know
How about resolving conflicts, i.e., files with the same name, different content? What about ownership conflicts? Not to say what happens when one filesystem becomes corrupted for one or another reason...
The best you can do is to just copy files from one filesystem to another; or, symlink files from one filesystem to another, depending on what you need.
