Recover preallocated space after a crash?

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

 



Hi list,
it is my understanding that XFS can preallocate some "extra" space via speculative EOF preallocation and speculative COW preallocation.

During normal system operation, that extra space is recovered after some time. But what if system crashes? Can it be even recovered? If so, it is done at mount time or via a (more invasive) fsck?

Thanks.
