Hi,
I found my aufs mount behaves not as expected.
According to the example from manpage, aufs mount behaves like this:
# mount -v -t aufs br:/day0:/base none /u
none on /u type aufs (rw,xino=/day0/.aufs.xino,br:/day0=rw:/
base=ro)
# mount -v -o remount,\
prepend:/day1,\
xino=/day1/xino,\
mod:/day0=ro,\
del:/day0 \
/u
none on /u type aufs (rw,xino=/day1/xino,br:/day1=rw:/base=ro)
But mine like this:
$ mount -v -t aufs -o br:/day0:/base none /u
none on /u type aufs (rw,br:/day0:/base)
$ mount -v -o remount,prepend:/day1,mod:/day0=ro,del:/day0 /u
none on /u type aufs (rw,br:/day0:/base,prepend:/day1,mod:/day0=ro,del:/
day0)
See, /day0 show up 3 times in mtab. But according to the manpage, it
should be removed from aufs mount table.
Anybody knows why (and fix)?
PS. My kernel and aufs are all 2.6.23
$ dpkg -l | grep 2.6.23
ii aufs-modules-2 0+20071211-1+g aufs modules for Linux (kernel 2.6.23-grml).
ii kqemu-modules- 1.3.0~pre11-7+ kqemu modules for Linux (kernel 2.6.23-grml)
ii linux-image-2. grml.06 Linux kernel binary image for version 2.6.23
$ uname -rm
2.6.23-grml i686
thanks
