Feature request - alternative method of activating nested replication #164

Open Peter2121 opened 3 years ago

Peter2121 commented 3 years ago

It would be nice to see a command-line argument that can replace ZREP_R environment variable, mainly for incremental replication. Starting such replication from cron, it is much more simple to add a command-line argument than setting an environment variable.

Funny thing.. it already does support it :)

underdocumented feature, mentioned in the comments around the variable:

If you want to recursively create/send snapshots, set this to -R # (or

use the -R option to BOTH zrep init and zrep sync #ZREP_R=-R

Sorry,

zstorage-1# zrep -i -R zdata/NFSROOT zstorage-2 zdata/NFSROOT
cannot open '-R': dataset does not exist
zstorage-1# zrep -R -i zdata/NFSROOT zstorage-2 zdata/NFSROOT
ERROR: unrecognized zrep subcommand -R

Hmm. odd.

in theory, the proper syntax should be

zrep -i -R ...

I shall look into it

Hi, I can confirm it does not work. I also tried various positions zrep -R -S pool/fs, zrep -S -R pool/fs and zre -S pool/fs -R.
