Subject: Recover preallocated space after a crash?
Date: Sat, 07 Nov 2020 20:55:50 +0100	[thread overview]
Message-ID: <274ec62926defe526850a4253d2b96a8@assyoma.it> (raw)

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.
