While I'm sure it's appreciated, I'd like to save the thanks until this is actually solved... It makes it easier for someone like me, who has to trawl through hundreds of pages of forum posts to find an answer.
Once again, Yvon, it sure would be nice of you to help a little on this current question. Having intimate knowledge of how your machine works, this is a question you should be able to answer rather easily. And it doesn't make any difference to me that it's "out of specification"... I imagine if this can be solved, Thecus will only benefit from having a more robust product. SO you should help!!!
Anyway...
So the question is, WHY can't /raid unmount. The system thinks it's being used for some reason.
Did a little checking... Found a debian forum where it is suggested that perhaps umount is failing due to running processes (daemonized, in their case).
Code:
N2100:/app/etc# umount -r /raid
umount: /dev/md0 busy - remounted read-only
N2100:/app/etc#
But as far as I can tell, this is not the case here:
Code:
Mem: 180364K used, 336344K free, 0K shrd, 57656K buff, 54448K cached
Load average: 0.01, 0.03, 0.00 (State: S=sleeping R=running, W=waiting)

Yes, there are plenty of priocesses running, but none of them should be running from /raid... Yet it is "busy" for some reason.
I also wanted to see what IS mounted as separate filesystems:
Code:
N2100:/app/etc# mount
rootfs on / type rootfs (rw)
/dev/root on / type ext2 (rw)
tmpfs on /var type tmpfs (rw)
devpts on /dev/pts type devpts (rw)
proc on /proc type proc (rw,nodiratime)
/dev/cloop0 on /usr/lib type ext2 (ro)
/dev/cloop2 on /opt type ext2 (ro)
/dev/mtdblock3 on /app type jffs2 (rw,noatime)
/dev/md0 on /raid type ext3 (rw,noatime,nodiratime)
N2100:/app/etc#
Finally, I wanted to see exactly what IS SUPPOSED to be mounted:
Code:
N2100:/app/etc# vi fstab
tmpfs /var tmpfs defaults 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
proc /proc proc defaults 0 0
none /sys sysfs defaults 0 0

Unfortunately, I'm not quite sure what to make of it.
There seem to be no processes running that would access /raid, and according to fstab, well I'm not sure... I expected to see a lot more there, based on how many things are mounted. At a loss for the moment. :-/
