We sometimes lose directory entries -- 'ls' or 'find' will not show every file present. The interesting thing is that if we reference the file directly, it can be opened. The missing files seem to share a common prefix with other files present, but that may be coincidental.
We were able to work around this problem by forcing a copyup of all directories -- by basically creating (then erasing) a file in each directory on the unionfs: for x in `find / -type d |grep -v ^/sys |grep -v ^/proc |grep -v ^/dev `; \ do touch $x/.unionfsfix ; rm $x/.unionfsfix ; done After this, all directory entries are visible and the system operates fine. As I haven't been able to find any reference to this problem in the unionfs archives... any ideas? (I realize 2.6.21.7 is old, but rebasing to a newer kernel will take a fair amount of work that we'd rather not underdake at the moment) # mount rootfs on / type rootfs (rw) /dev/root on / type squashfs (ro) tmpfs on /dev/shm type tmpfs (rw) /dev/root on /dev/shm/.rootfs type squashfs (ro) /dev/mtdblock5 on /dev/shm/.featfs type squashfs (ro) unionfs on / type unionfs (rw,dirs=/dev/shm/.overlay=rw:/dev/shm/.featfs=ro:/dev /shm/.rootfs=ro) tmpfs on /tmp type tmpfs (rw) procdev on /proc type proc (rw) ptsdev on /dev/pts type devpts (rw) /sys on /sys type sysfs (rw) - Solomon -- Solomon Peachy [EMAIL PROTECTED] AbsoluteValue Systems http://www.linux-wlan.com 721-D North Drive +1 (321) 259-0737 (office) Melbourne, FL 32934 +1 (321) 259-0286 (fax)
