A huge response yet again.

1st must apologise for stating nfs instead of UFS. Still much of the
consensus seems to be with advfs, particularly for high capacity
systems. I accept the argument that waiting for an fsck over all the
volumes on system with even a small - by today's standards -
system would take a hell of a long time and would been a major
headache. Some see ufs as the way things were and advfs as the
way file systems will go.

Still I wouldn't write off UFS and I had a mail from someone working
on the development of UFS who states categorically that UFS is not
being phased out but quite the contrary being improved on. And
unlike advfs there is not need for an additional license to use the
really useful stuff like addvol. I am not sure what the size limits are
for UFS but I guess they will be increasing.

As for my root disk, I can leave it as it is for now. I would like addvol
and hope to get a license soon but it not critical as the external disks
have plenty of space.

I should mention Joe Flecther how pointed out my error, Jim
fitzmaurice for a very convincing pro advfs piece, Chang Song for a
ufs view point and Ettore Aldrovandi.


Thanx
Dp.

Hi Managers,
        DS10,alpha tru64 5.1 with Storageworks pedestal and 4x 35GB
                disks. Internal disk is 10GB.
Q) Do I create 3 file domains on the boot disk?
Q) If you do have a disk failure on a multiple volume domain, can
you recover any of the data from the good drive(s)?
Q) Is there any way on knowing on which disk the data is stored?
Q) Should I stick to nfs or are the real advantages to advfs.
