this?

Harald,
I can only give you my recommendations, I suppose.
I would have my root file system be ext3. Any file systems that are being
shared read-only, I would make ext2. (If it's not mounted read-write,
there's no need for journaling.)
Based on a performance presentation at SHARE, there is a

Moloko,
you may want to check /proc/subchannels, whether the DASD
has really been attached to your system, and whether there is
a path available (boolean AND of PIM/PAM/POM). If so, a
'echo set 7240 on /proc/dasd/devices' may make the DASD
visible to the DASD driver.

or RAID. RAID if you don't anticipate having to add/remove a particular

Pretty much. There are other file systems that could/should be broken out
from root, such as /tmp, /var, but in the particular case you asked about,
yes.

Jim,
I don't think those two statements are either necessarily correct, or
incorrect. I would say that the trick is that the first cylinder to be
dumped to tape (and restored to disk at real cylinder 0) needs to be what
the Linux/390 system thinks is cylinder 0. That's where the IPL record
Jim,
What would you like, specifically? From what I gather, you could:
1) Create a 3390-9 or -27 for the /usr partition. The problems are (a)
possible I/O queueing to the physical device, (b) not have a correspondingly
sized volume for D.R. purposes.
1a) True. But I think this is also true of

Well then, how would you recommend this be done? I have no decent facility
at disaster recovery to IPL a recovery CD and mount the disk images to

I've noticed that when the dasdfmt program formats a cdl volume, there
is one thing missing. DS1LSTAR is not set.
Is this by design or just because it was too much of a bother to put it in
there?
The only thing that this would get me would be the ability to use ftp on
MVS to send the entire

These assume you don't care about the value, just want a steady stream of
