Depends if the driver does 32-bit block numbers with signed or unsigned values. The absolute maximum supported by 2.4 kernels is 2TB devices.

Beta 7 has the PE alignment bug, so you should upgrade the tools even if you can't upgrade the kernel. > Here is the current filesystem and size: > > /dev/exp300_2/exp300_lv2 924160464 891307744 32852720 97% /files1 > Q: Why are my logical volumes limited to 256 GB in size? > A: This is NO absolute limit but it depends on the physical extent size > you configured at volume group creation time. Check what "pvdata -P /dev/whatever" tells you about the PE size. If it is 16386kB, then you are limited to 1TB in size. If it is larger than that, you _may_ be able to go past 1TB, but you may not, depending on whether your drivers and kernel work properly or not.
