Hi
Yet, what makes me headaches is, that gstat will only the the forces writes
status, if it was ealier set using gfix. This looks like gfix is adding
something that gstat will show besides really switching on forced writes.
Which once again might mean, that it could be possible that the real forced
write flag is modified without modifying the header that gstat shows,
leading to a situation where gstat reports forced writes while it is not
really in effect...
Besides these thoughts, I am still seeking for a way to confirm, that these
databases are in forced writes mode without modifying them in any way.
Is there no such tool? [It need to be on command line, but if it is only a
flag (read: bit) in the first block of the file, that information would
suffice...)
Regards,
Steffen
