Your package installation is broken. The package 'ownCloud; is installed in /i-data/5c72062c/.PKG/ownCloud/, and the subdirectory zypkg_conf/info/ should contain a file ownCloud.control and some other files, which are extracted from control.tar.gz in the zypkg file.

This control file is used to read the version of the package, to decide if a newer one is available. When it lacks apparently the install status is 'unknown'.

The infomation in the control file is redundant, the data can also be found in /etc/zyxel/pkg_conf/status which is stored on a flash partition.

I *think* your /i-data/5c72062c/.PKG/ directory (which is on harddisk) is damaged.

so i can opy this info over from /etc/zyxel... and it should work again?
what puzzles me is that i cannot even install apps that have never been installed, or were uninstalled

now thats crazy /i-data/sysvol/.PKG is not a directory cat shows its a php script ?!?

I don't think so. As your log shows more lacking control files, I doubt that this are the only lacking files. Just the only ones that are checked/logged by the package manager.

Do you have a log from that?

ok, i backed up .PKG file (which was part of phpmyadmin) and created a directory named .PKG instead, now i was able to install NFS, thats great, even if its unconfigured now, but it still shows me phpmyadmin and owncloud as broken (obviously) 
can i somehow restore their state and  would i loose my owncloud data if I uninstall it? 
I knew there would be some corruption in my data as I had 2 disks broken and only could put a copy made using ddrescue back in to get it working (somehow) again. I'm still on a degraded array as the second replacement disk (and another spare disk)  hasn't arrived yet.

I think the config of owncloud should be in .../.PKG/ownCloud/etc/. When you lost that directory the config is lost, else you could try to install ownCloud, and copy over the contents of .../etc/ (while ownCloud is not running).

AFAIK the owncloud data is on the shares. But parts of it could also be in .../.PKG/ownCloud/var/, or something like that.

Luckily I had moved over the owncloud storage into one of my shares and had set a symlink to its original path,  so I only lost the symlink (hadn't remembered that)  so everything is fine,  MySQL and owncloud are up and running again,  MySQL is restoring from backups right now,  I will catch the owncloud content on a client via nfs and sync it back to the new instance on the weekend. 
Anyway,  thanks for your useful hints,  would have a few more grey hairs now otherwise.
