Re: [Jfs-discussion] maximum filesystem size limit

Can someone please tell me if I can use JFS to create a single 12TB
filesystem under Linux?

Afaik, you have a problem here concerning the Linux 2.4 maximum block device 
size of 2TB.

Anyone that knows if there's a workaround for this using LVM or something?

why reply if you are only guessing?

status of 2.5 64-bit sector_t patches looks promising, will likely end
up on 2.5 soonish.

No, not Linus 2.5.  It is in Andrew Morton's -mm tree though.  That should
mean that after some heavy pounding on the code (what else would you expect
from akpm?) it will probably be in 2.5-linus soon...
