Situation:
My current storage needs are approximately 1.5 TB annually. This will
increase to about 3.5 TB annually over the next 5 years (rough est.). This
box will just be a data archive and once it is full it will only be used very
infrequently if not used at all. Files are small up to 10 MB but numerous.
CentOS:
Upgrading to the newer CentOS flavors. I will not have the ability to
archive this data to tape and I am concerned about loosing the data when
upgrading the OS. How best to handle this?
You have to be careful, but it's quite easy to leave partitions (and thus
their data) alone when you are updating/reinstalling the OS.
Storage limitation. It is my understanding that there is a 2 TB storage
limitation with Linux (and windows) in general particularly for stability. I
see that ReiserFS can go up to 16 TB. Is any one using this? If so, how has
it been for you?
You cannot boot from a device larger than 2TiB, but that's the only
limitation at that size. I run several multi-TB servers (including over
8TB) on CentOS-5 with no issues (using ext3).
You do not want to use ReiserFS. It's not supported under CentOS, and
it's future is far less than certain (and I do not want to restart *that*
OT conversation). ext3 is the default FS under CentOS and works pretty
well.
