> Excerpts from Erik Jensen's message of 2011-08-03 02:57:24 -0400:
>> The lack of any information on when btrfsck might be ready is a real
>> headache to those deciding what to do with a corrupted file system.
>>
>> I am currently sitting on a btrfs array of 10 disks that has been
>> reporting "parent transid verify failed" since last November. While
>> the data on the drive is by no means irreplaceable, it would take a
>> fair amount of effort. At the time I was told that a btrfsck would
>> almost certainly be released by the end of the year. In January, it
>> was "finally almost ready", and toward the end of May it was going to
>> be released in "a couple of days
>> (hopefully)".
>>
>> Had I known back in November 9 months would go by with no such tool, I
>> would have certainly wiped the array and started over, as it was
>> certainly not worth the wait. So here I am, several assurances of
>> imminent release later, still wondering whether it would be better to
>> wait or cut my losses.
>>
>> I understand that everyone is working hard, and I deeply appreciate
>> the effort being put into this filesystem. I'm not looking for an
>> exact date, just a rough order of magnitude on which to base
>> decisions.
