I got a bunch of new disks on one of our systems and wanted to transfer an existing pool over to them so what I did was this:
zfs snapshot -r old-pool@replicaton zfs send -R old-pool@replication | mbuffer -m 1G | zfs receive -F -d new-pool
but then halfway through the operation, I got a warning from
zfs send, complaining
that the snapshot
old-pool/some/fileset@replication would not exist ...
when I went to investigate, I found indeed that
zfs snapshot -r had
neglected to create a snapshot on
old-pool/some/fileset. So I
zfs list -r -o name old-pool | \ xargs -n1 perl -e 'system "zfs","list",$ARGV."\@replication"'
and found that there were about 10% of the filesets which were lacking this snapshot ...
I then proceeded to create the missing snapshot individually, and it worked fine.
I have since repeated the experiment and found the same problem again ...
Any idea how this can be?
