Can someone give a short tutorial of how mounting works in vsta. I
either don't understand it correctly, or I've got some misconceptions.
First, I was under the impression that it was possible to mount a
filesystem on top of a directory and still be able to see the existing
directory (stackable or translucent filesystems). I haven't been able
to figure out how to do this.
Second, I've created a large file in the / directory on a dos
filesystem with the mkfs_vfs program, and then run a vstafs server
using it as the datastore. This works fine and I can mount it and
use it (way cool!). I mounted it as /v and copied /vsta to /v.
Then I tried mounting the vstafs filesystem on /vsta. That worked.
So then I removed everything from the /vsta directory on the dos
partition that wasn't needed for booting, and changed the inittab
and fstab files to automatically start the vstafs and mount it on
/vsta.
After rebooting, things seemed okay, except that some things quit
working properly. ps started giving weird results in the USR/SYS
column, and vi and less started complaining about the terminal type
not being found. Basically, it appered that for certain operations,
the /vsta directory on the dos filesystem was being searched, and not
the /vsta filesystem being served by the vstafs server.
Any help in clearing up my understanding of this would be greatly
appreciated.
Thanks.
