Hello, Junjiro and list, I do not know if it is a problem of aufs, but it can be and I expose the problem in this list
I am using the new kernel sidux-amd64 2.6.29-0.slh.1 in a Live system, This kernel has aufs2 integrated (non-module) and squasfs 4.0 (module), the file system mounting is as follows: # mount tmpfs on /lib/init/rw type tmpfs (rw,nosuid,mode=0755) proc on /proc type proc (rw,noexec,nosuid,nodev) sysfs on /sys type sysfs (rw,noexec,nosuid,nodev) procbususb on /proc/bus/usb type usbfs (rw) udev on /dev type tmpfs (rw,mode=0755) tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev) devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=620) rootfs on / type rootfs (rw) /dev/sda1 on /lnet/image type ext3 (ro,noatime,errors=continue,data=ordered) tmpfs on /lnet/cow type tmpfs (rw,noatime,size=2061756k) tmpfs on /lnet/xino type tmpfs (rw) tmpfs on /lnet/uloop type tmpfs (rw,size=2061756k) /dev/loop0 on /lnet/00filesystem.squashfs type squashfs (ro,noatime) /dev/loop1 on /lnet/10tws.squashfs type squashfs (ro,noatime) /dev/loop2 on /lnet/90pcjordi.squashfs type squashfs (ro,noatime) /dev/sda6 on /home type reiserfs (rw,noatime) /dev/sda2 on /media/winxp type ntfs (ro,noexec,nosuid,nodev,dmask=0022,fmask=0133,nls=utf8) /dev/sda5 on /media/windows type vfat (rw,noexec,nosuid,nodev,iocharset=cp850,utf8,quiet,umask=000,shortname=lower) /home/JPLive/cacheapt-amd64 on /var/cache/apt type none (rw,bind) /home/JPLive/libapt-amd64 on /var/lib/apt type none (rw,bind) /dev on /tmp/live-net-remaster-prohO3/chroot/dev type none (rw,bind) /dev/pts on /tmp/live-net-remaster-prohO3/chroot/dev/pts type none (rw,bind) when executing the remount command in the mount point, the system answers: # mount -o remount,rw /lnet/image Killed. can see a dump in / var/log/messages, that is attached and when executing the remount in the device, it works: # mount -v -o remount,rw /dev/sda1 /dev/sda1 on /lnet/image type ext3 (rw,noatime,errors=continue,data=ordered) to verify, issue a mount command: # mount /dev/sda1 on /lnet/image type ext3 (rw,noatime,errors=continue,data=ordered) Can you say an opinion about where the problem can be, Thanks in advance, Jordi Pujol
