We use Linux (openSuse 13.1, Kernel: 3.11.10 atm) Today I do some testing on the drive and it seems, that blocksizes up to 512k working fine so far. But going to 1M can lead to ebusy errors.
For productive use I am fine with lower blocksizes (even with the default of 64k). In our setup its just a "nice to have" but not essential. Maybe there are differences in the LTO generations and / or tapedrives.
