[PATCH] nvme/012 & 013: avoid extremely slow xfs IO

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



It is observed that nvme/012 may take ~17 minutes to complete on aarch64,
even worse it may trigger IO timeout on nvme-loop.

Eric and Dave replied that it is because of too small log size on small
disk.

So pass '-l size=32m' to avoid the issue.

With this patch, nvme/012 can be completed in one minute.
