RE: [Zope-dev] ANNOUNCE: Zope 2.4.0 alpha 1 released
My impression is that FileStorage implements a 32-bit id-type-thingy somewhere (look at ZODB docs, I think there is something about this somewhere), which limits it (in addition to the Linux kernel ext2 fs limit), to < 2GB. With 7.5 GB, I'd use a more advanced storage like the new - well, not quite released ;) - Berkeley (libdb3 based) storages, though I haven't tried anything like that myself... Does anyone have any comments on the reliability of PartitionedFileStorage in this regard as a temporary solution? Is anyone using PartitionedFileStorage in a production environment?

Now comes a tricky question: Suppose we are running a Linux Kernel 2.4.x and using the latest Python 2.x distribution. And supposing we can recompile all code if neccessary: How large can a Data.fs grow until it breaks ? We need to be able to store about 7.5 GBytes (note: Gigabytes) in the ZODB. I would rather use the ZODB than a LocalFS .... Thanks in advance - Holger Am Donnerstag, 31. Mai 2001 22:55 schrieb Brian Lloyd:

FileStorage does *not* have a 2GB limit. The only 2GB limit is the old Linux filesystem limit. I know this, because I've had >2GB Data.fs files on FreeBSD. --RDM
As one more example, Zope.org is currently at 4.8 Gb on FileStorage. --Paul "R. David Murray" wrote:

Berkeley is a good recommendation.
Does anyone have any comments on the reliability of PartitionedFileStorage in this regard as a temporary solution? Is anyone using PartitionedFileStorage in a production environment?
AFAIK no. Its functionality has already been superceded. Shane
