When testing 512 block size xfs, xfs/074 fails as
QA output created by 074
+fallocate: No space left on device
Silence is golden
That's because
40051712*512=20G < 30G.
And quote from Dave:
That was sized to give AGs of a specific size, which originally
contributed to the problem being exposed. You should change the block
count specification to a size specification so the filesysetm being
made on 4k block size filesystems remains unchanged.
size =
40051712b
=
40051712 * 4096
= 164,051,812,352
= 156452m
So set the filesystem size to 156452m explicitly.
