We have a number of storage pools that report "16.0E" for the "freeing"
property. Using "-p" to get a more precise number, we have values like
these:
18446744072282297939
18446744073709544128
18446744073709549120
or, as signed 64-bit values:
-1427253677
-7488
-2496
Have others seen this? Given that this seems to indicate that we've freed
more data than we expected to, could this be indicative of corruption?
In case it's relevant: most of the affected systems were previously
affected by spacemap corruption related to async destroy[1]. But the
system with the largest negative value was installed recently and has only
ever run bits as new as February.[2]
Thanks,
Dave
