Hi,
do you also use a clustered-LVM in your storage system.
i mean, two storages mirrored in a cluster (cmirror ?).
kind regards

Hi,
I'm the system administrator of PADICAT (http://www.padi.cat). It
collects Catalan (http://en.wikipedia.org/wiki/Catalonia) web sites to
provide permanent access to them (http://www.padi.cat/en/quees.php).
It's equivalent to Internet Archive (http://www.archive.org) but for a
particular culture.
Our software developers require us to have one large file system,
actually a single directory, with all this historically-classified web
sites on a gziped file.
I'm currently studying lustre and other HPC-related file systems to get
this large file system, but by now I have ext3 as our file system. Next
Monday I'm planning to extend it to 3TB o 4TB, so I'm currently
researching for restrictions because during next month I'll have between
3TB to 4TB more to add: so, it will become a 8TB file system.
Last time I fsck my 2'1TB file system I spend about 2 hours. Anyway, I'm
also curious about the maximums :P
Thanks,
Jordi

Hi all,
I found on a webpage this two sentences:
- The combination of 32-bit CPU and Linux kernel version 2.6.x, the
limit of logical volume size is maximized at 16TB.
- For Linux kernel 2.6.x running on 64-bit CPU, the maximum LV size is
8EB (extremely terrible big storage for this time being!)
Are they right?
Ok. But it's really impractical to have large multi-terabyte
single filesystem today. What are you wanting to do? Ever fsck a
2TB filesystem? Consider yourself warned.
Or... were you just curious about the maximums?
