While not strictly a ZFS issue as such I thought I'd post here as this and the

Has anyone seen soft corruption in NTFS iSCSI ZVOLs after a power loss?
I mean, there is no guarantee writes will be executed in order, so in theory,
one could corrupt it's NTFS file system.
Would best practice be to rollback the last snapshot before making those iSCSI
available again?
