Is --reflink on XFS atomic? In particular for a VM file that's being used, that's possibly quite a lot of metadata on disk and in-flight in the host and in the guest. I ask because I'm not certain --reflink copies on Btrfs are atomic, I'll have to ask over there too. Whereas btrfs subvolume snapshots are considered atomic.
Hi, I did that question some time ago and, based on what I read here [1], it *should* be atomic.
Feel free to correct me, anyway. [1] https://www.spinics.net/lists/linux-xfs/msg15969.html -- Danti Gionatan Supporto Tecnico Assyoma S.r.l. - www.assyoma.it email: g.danti@xxxxxxxxxx - info@xxxxxxxxxx GPG public key ID: FF5F32A8
