Well, please not too many. BTW, which tools do You consder missing except
mabe those to resize file systems?
As far as i remember, the equivalents to the AIX cli commands to amage
physical and logical volumes are all there, and file systems are, strictly
spoken, a different issue. One could easily consider running LVM on UFS or
the (hopefully) forthcoming
journaled file system SGI has just contributed to linux instead of good old

My impression is that the major companies are a bit unaware of debian and
recognize only Redhat and partly Suse (which i'm tired of), at least Oracle,
IBM, SGI and HP. But isn't this a bit off topic here?

How do You integrate with ADSM (except over NFS)? As far as i know, only the
ADSM client is supported on Linux.

Finally: i have the impression that the major arguments of the necessity of
LVM support in the stock linux kernel
have been brought up for several times now. What about summing them up and
collecting the Names of the contributors to this thread into the note to be
sent to Linus?
