Thanks to the ever-helpful Dr. Tom Blinn for replying to my message
about vrestore and quotas.
Reminder: if you run vrestore into an advanced file system then by
default it will silently change the size of the fileset to that of the
fileset you dumped.
Tom suggested I make a support call and report it as a high priority
problem, stressing that I consider it a file system corrupter, that is
it makes the file system metadata inconsistent, and does so without
any warning or opportunity to avert the action.
I will do this; the reason I haven't done so yet is that I am
attempting to register for online services and haven't succeeded
yet. If necessary I'll use the cumbersome traditional method and yet
again recite over the phone my e-mail address and phone number and
explain the problem to a non-specialist.
I've thought a bit more about what vrestore should do. I don't know
precisely what happens when it updates quota information, but I would
like to see:
(a) '-o ask' should always be the default. The situations you don't
want it are very rare.
(b) vrestore should never explicitly change disc usage information,
this should be left to the normal kernel mechanisms.
(c) it should not change user quota information without permission.
(d) it should not change fileset quota without information. The
question should be separate from that for (c).
Regards,
Bob
