RE: RE: Re: Drop DBSpace

In Response To: RE: Re: Drop DBSpace (Marcus Haarmann)

Hi all,

I found an empty table referencing the blobdbs, but after modification
of the column (now also blob) still no luck.
I checked all dbschema for further references, oncheck -pB for all DB,
oncheck -pe shows only OVERHEAD of 98k,
no other usage.

Anybody ?

Hi John,

Does not work ...

onspaces -d blobdbs -f
Cannot drop a 'blobspace' using the -f flag.

Any other hints ?
