I'm looking to use ZFS to export ISCSI volumes to a Windows/Linux client.
Essentially, I'm looking to create two storage ZFS machines that I will export
ISCSI targets from. Then from the client side, I will enable mirrorings. The
two ZFS machines will be independent of each other. I had question about
snapshoting of ISCSI zvols.
If I do a snapshot of ISCSI volume, it snapshots the blocks. I know the
sending the blocks will allow from some from of replication. However, if I
send the snapshot to a file, will I be able to recover the ISCSI volume from
the file(s)?
e.g.
zfs send tank/t...@1 | gzip -c> zfs.tank.test.gz
Can I recover this ISCSI volume from zfs.tank.test.gz by sending it directly to
another ZFS machine?
Yes. The send data stream is just that, a stream of data. If you want
to archive the file, do a test receive first to make sure there isn't
any data corruption.
Will I then be able to mount the ZFS volume created from this file and have my
filesystem be the way it was?
Yes.
