Cannot use --features=compressed even if both SRC and DST are compressed (invalid option 'c') #481

Closed gabviv73 closed 3 years ago

gabviv73 commented 4 years ago

I would like to transfer compressed streams over a slow WAN link, so I've setup --features=compressed

This is my dataset in znapzend:

# znapzendzetup export DATA/mysql

dst_quantum=root@10.0.254.100:DISKB/znapzend/emip/DATA/mysql
dst_quantum_plan=7days=>1hours,30days=>2hours,90days=>1days,1years=>1weeks,10years=>1months
dst_znapzend=root@znapzend.rvmgroup.local:BACKUP/znapzend/emip/DATA/mysql
dst_znapzend_plan=7days=>1hours,30days=>2hours,90days=>1days,1years=>1weeks,10years=>1months
enabled=on
mbuffer=off
mbuffer_size=1G
post_znap_cmd=off
pre_znap_cmd=off
recursive=off
src=DATA/mysql
src_plan=1days=>1hours,3days=>2hours,14days=>990minutes
tsformat=%Y-%m-%d-%H%M%S
zend_delay=0

SRC and DST have compression turned on

# zfs get all DATA/mysql | grep -w compression DATA/mysql compression on inherited from DATA

# zfs get all DISKB/znapzend/emip/DATA/mysql | grep -w compression DISKB/znapzend/emip/DATA/mysql compression on inherited from DISKB

But when the job is run, I got these errors:

OS details:

Suggestions ?

crabique commented 4 years ago

modinfo zfs? ZFS ≤0.6 doesn't support compressed send/recv.

gabviv73 commented 4 years ago

On SRC: # modinfo zfs | grep ^version: version: 0.6.5.9-5

On DST: # modinfo zfs | grep ^version: version: 0.7.12-2+deb10u1

So I need to upgrade packages on SRC ?

crabique commented 4 years ago

Yes.
