[OpenAFS] volume size
Fri, 14 Jan 2011 11:43:50 -0500
I'm wondering what is a reasonable size for large AFS volumes. I
understand that the maximum size of a volume is about 2 TB (assuming
that the partition is at least that size). From a practical standpoint,
is it reasonable to have a 2 TB volume? Should I expect any problems
doing operations like bos salvage or vos move on large volumes?
For example, I'm wondering if bos salvage has a "harder" time with a few
large volumes than with several smaller volumes. I figure that, with
smaller volumes, internal inconsistencies that bos salvage fixes would
be more isolated than with large volumes, and that that would be
beneficial. But I don't really know.
Currently we mount 25 GB volumes in users' home directories for their
image data, which grows a lot during data processing. Some users are
starting to feel limited by 25 GB volumes, so I'm considering going to
100 GB volumes. I would appreciate any advice. Should large volumes be
salvaged more often than small volumes?
We're running openafs 1.4.11 on centos 5.3.
