Hello, Is it possible to detach a clone from its snapshot (and copy all its data physically)? I ran into an obscure situation where 'zfs promote' does not help.
Snapshot S has clones C1 and C2, both of which are boot environments. S has a
data error that cannot be corrected. The error affects *one* crash dump file,
so it's obviously benign. (The system crashed when a crash dump was being
transferred from the dump device to /var/crash and this happened more than
once. This is a nightly + onu system, so accidents might happen.)
If I understand it well, the original dependency graph looks like this
C1 -> S <- C2,
and I can only achieve one the following with 'zfs promote':
C1 <- S <- C2
C1 -> S -> C2
I can't get rid of S (and of the error message in zpool status) without
removing either C1 or C2. Is there a solution other than removing C1 or C2?
