 |
|
Hi guys.
Well, I'm playing with diskless stations and would ask this question. Is that possible to combine (or merge) 2 filesystems? Let say I have:
hda1:
| Code: | /
-/dir0
-/dir1
-/dir2
-/dir3 |
hdb1:
| Code: | /
-/dir1
-/dir2
-/dir3
-/dir4 |
As you see these 2 drives has some directories (dir1, dir2, dir3) which has same names. Only names, not the content. So, is that possible to mount them somehow to SAME directory, so I just have
| Code: | /
-/dir0
-/dir1
-/dir2
-/dir3
-/dir4
|
but the content of dir1, dir2 and dir3 is combined using content of these directories on both hda1 and hdb1 partitions? There could be a problem, if let say hda1:/dir1 and hdb1:/dir1 has 2 files with same name, content one of them should be used (lets say that depends on hda1 and hdb1 mount order).
I'm wondered does LVM2 could do this sort of things? |
