[LU-2431] llmount.sh fails with FSTYPE=zfs

Tue, 11 Dec 2012 13:08:17 +0000

After 682f3e19 running llmount.sh with FSTYPE=zfs fails while trying to create the MGS:

# FSTYPE=zfs ./lustre/tests/llmount.sh

mkfs.lustre FATAL: Unable to create filesystem lustre-mgs/mgs (256)

mkfs.lustre FATAL: mkfs failed 256

Is this a "supported" usage of llmount.sh? If not then whet is the recommended way of setting up a small zfs instance for test purposes?

I got it back to the combined MDT/MGS case by default using the following patch. But there would still seem to be some issues with the non-combined case.
